You can easily view a matrix as an array and vice versa using -the MatrixBase::array() and ArrayBase::matrix() functions respectively. Here is an example: -\code -Vector4f a, b, c; -c = a.array() * b.array(); -\endcode -Note that the .array() function is not at all a synonym of the deprecated .cwise() prefix. -While the .cwise() prefix changed the behavior of the following operator, the array() function performs -a permanent conversion to the array world. Therefore, for binary operations such as the coefficient wise product, -both sides must be converted to an \em array as in the above example. On the other hand, when you -concatenate multiple coefficient wise operations you only have to do the conversion once, e.g.: -\code -Vector4f a, b, c; -c = a.array().abs().pow(3) * b.array().abs().sin(); -\endcode -With Eigen2 you would have written: -\code -c = (a.cwise().abs().cwise().pow(3)).cwise() * (b.cwise().abs().cwise().sin()); -\endcode - -\section PartAndExtract Triangular and self-adjoint matrices - -In Eigen 2 you had to play with the part, extract, and marked functions to deal with triangular and selfadjoint matrices.

In Eigen 3, it takes a new \a Mode template parameter, which indicates whether it's \a Projective or \a Affine transform. There is no default value. - -The Transform3f (etc) typedefs are no more.

- - -\section LazyVsNoalias Lazy evaluation and noalias - -In Eigen all operations are performed in a lazy fashion except the matrix products which are always evaluated into a temporary by default. -In Eigen2, lazy evaluation could be enforced by tagging a product using the .lazy() function. However, in complex expressions it was not -easy to determine where to put the lazy() function. In Eigen3, the lazy() feature has been superseded by the MatrixBase::noalias() function -which can be used on the left hand side of an assignment when no aliasing can occur. Here is an example: -\code -MatrixXf a, b, c; -... -c.noalias() += 2 * a.transpose() * b; -\endcode -However, the noalias mechanism does not cover all the features of the old .lazy(). Indeed, in some extremely rare cases, -it might be useful to explicit request for a lay product, i.e., for a product which will be evaluated one coefficient at once, on request, -just like any other expressions. To this end you can use the MatrixBase::lazyProduct() function, however we strongly discourage you to -use it unless you are sure of what you are doing, i.e., you have rigourosly measured a speed improvement. - -\section AlignMacros Alignment-related macros - -The EIGEN_ALIGN_128 macro has been renamed to EIGEN_ALIGN16. Don't be surprised, it's just that we switched to counting in bytes ;-) - -The EIGEN_DONT_ALIGN option still exists in Eigen 3, but it has a new cousin: EIGEN_DONT_ALIGN_STATICALLY. It allows to get rid of all static alignment issues while keeping alignment of dynamic-size heap-allocated arrays, thus keeping vectorization for dynamic-size objects. - -\section AlignedMap Aligned Map objects - -A common issue with Eigen 2 was that when mapping an array with Map, there was no way to tell Eigen that your array was aligned. There was a ForceAligned option but it didn't mean that; it was just confusing and has been removed. - -New in Eigen3 is the #Aligned option. See the documentation of class Map.

This happens when the same identifier is used in Eigen 2 and in Eigen 3 with different meanings. To help migrate projects that rely on such API, we provide a staged migration path allowing to perform the migration \em incrementally. - -It goes as follows: -\li Step 0: start with a project using Eigen 2. -\li Step 1: build your project against Eigen 3 with \ref Stage10 "Eigen 2 support stage 10". This mode enables maximum compatibility with the Eigen 2 API, with just a few exceptions. -\li Step 2: build your project against Eigen 3 with \ref Stage20 "Eigen 2 support stage 20". This mode forces you to add eigen2_ prefixes to the Eigen2 identifiers that conflict with Eigen 3 API. -\li Step 3: build your project against Eigen 3 with \ref Stage30 "Eigen 2 support stage 30". This mode enables the full Eigen 3 API. -\li Step 4: build your project against Eigen 3 with \ref Stage40 "Eigen 2 support stage 40". This mode enables the full Eigen 3 strictness on matters, such as const-correctness, where Eigen 2 was looser. -\li Step 5: build your project against Eigen 3 without any Eigen 2 support mode. - -\section Stage10 Stage 10: define EIGEN2_SUPPORT_STAGE10_FULL_EIGEN2_API - -Enable this mode by defining the EIGEN2_SUPPORT_STAGE10_FULL_EIGEN2_API preprocessor macro before including any Eigen 3 header. - -This mode maximizes support for the Eigen 2 API. As a result, it does not offer the full Eigen 3 API. Also, it doesn't offer quite 100% of the Eigen 2 API. - -The part of the Eigen 3 API that is not present in this mode, is Eigen 3's Geometry module. Indeed, this mode completely replaces it by a copy of Eigen 2's Geometry module. - -The parts of the API that are still not 100% Eigen 2 compatible in this mode are: -\li Dot products over complex numbers. Eigen 2's dot product was linear in the first variable. Eigen 3's dot product is linear in the second variable. In other words, the Eigen 2 code \code x.dot(y) \endcode is equivalent to the Eigen 3 code \code y.dot(x) \endcode In yet other words, dot products are complex-conjugated in Eigen 3 compared to Eigen 2. The switch to the new convention was commanded by common usage, especially with the notation \f$ x^Ty \f$ for dot products of column-vectors. -\li The Sparse module. -\li Certain fine details of linear algebraic decompositions. For example, LDLT decomposition is now pivoting in Eigen 3 whereas it wasn't in Eigen 2, so code that was relying on its underlying matrix structure will break. -\li Usage of Eigen types in STL containers, \ref Eigen2ToEigen3 "as explained on this page". - -\section Stage20 Stage 20: define EIGEN2_SUPPORT_STAGE20_RESOLVE_API_CONFLICTS - -Enable this mode by defining the EIGEN2_SUPPORT_STAGE10_FULL_EIGEN2_API preprocessor macro before including any Eigen 3 header. - -This mode removes the Eigen 2 API that is directly conflicting with Eigen 3 API. Instead, these bits of Eigen 2 API remain available with eigen2_ prefixes. The main examples of such API are: -\li the whole Geometry module. For example, replace \c Quaternion by \c eigen2_Quaternion, replace \c Transform3f by \c eigen2_Transform3f, etc. -\li the lu() method to obtain a LU decomposition. Replace by eigen2_lu(). - -There is also one more eigen2_-prefixed identifier that you should know about, even though its use is not checked at compile time by this mode: the dot() method. As was discussed above, over complex numbers, its meaning is different between Eigen 2 and Eigen 3. You can use eigen2_dot() to get the Eigen 2 behavior. - -\section Stage30 Stage 30: define EIGEN2_SUPPORT_STAGE30_FULL_EIGEN3_API - -Enable this mode by defining the EIGEN2_SUPPORT_STAGE30_FULL_EIGEN3_API preprocessor macro before including any Eigen 3 header. Also, this mode is what you get by default when you just define EIGEN2_SUPPORT. - -This mode gives you the full unaltered Eigen 3 API, while still keeping as much support as possible for the Eigen 2 API. - -The eigen2_-prefixed identifiers are still available, but at this stage you should now replace them by Eigen 3 identifiers. Have a look at our page on \ref Eigen2ToEigen3 "API changes" between Eigen 2 and Eigen 3. - -\section Stage40 Stage 40: define EIGEN2_SUPPORT_STAGE40_FULL_EIGEN3_STRICTNESS - -Enable this mode by defining the EIGEN2_SUPPORT_STAGE40_FULL_EIGEN3_STRICTNESS preprocessor macro before including any Eigen 3 header. - -This mode tightens the last bits of strictness, especially const-correctness, that had to be loosened to support what Eigen 2 allowed. For example, this code compiled in Eigen 2: -\code -const float array[4]; -x = Map(array); -\endcode -That allowed to circumvent constness. This is no longer allowed in Eigen 3. If you have to map const data in Eigen 3, map it as a const-qualified type. However, rather than explictly constructing Map objects, we strongly encourage you to use the static Map methods instead, as they take care of all of this for you: -\code -const float array[4]; -x = Vector4f::Map(array); -\endcode -This lets Eigen do the right thing for you and works equally well in Eigen 2 and in Eigen 3. - -\section FinallyDropAllEigen2Support Finally drop all Eigen 2 support - -Stage 40 is the first where it's "comfortable" to stay for a little longer period, since it preserves 100% Eigen 3 compatibility. However, we still encourage you to complete your migration as quickly as possible. While we do run the Eigen 2 test suite against Eigen 3's stage 10 support mode, we can't guarantee the same level of support and quality assurance for Eigen 2 support as we do for Eigen 3 itself, especially not in the long term. \ref Eigen2ToEigen3 "This page" describes a large part of the changes that you may need to perform. - -\section ABICompatibility What about ABI compatibility? - -It goes as follows: -\li Stage 10 already is ABI compatible with Eigen 3 for the basic (Matrix, Array, SparseMatrix...) types. However, since this stage uses a copy of Eigen 2's Geometry module instead of Eigen 3's own Geometry module, the ABI in the Geometry module is not Eigen 3 compatible. -\li Stage 20 removes the Eigen 3-incompatible Eigen 2 Geometry module (it remains available with eigen2_ prefix). So at this stage, all the identifiers that exist in Eigen 3 have the Eigen 3 ABI (and API). -\li Stage 30 introduces the remaining Eigen 3 identifiers. So at this stage, you have the full Eigen 3 ABI. -\li Stage 40 is no different than Stage 30 in these matters. - - -*/ - -} diff --git a/testbed/nanogui/ext/eigen/doc/AsciiQuickReference.txt b/testbed/nanogui/ext/eigen/doc/AsciiQuickReference.txt deleted file mode 100644 index b9f497f8..00000000 --- a/testbed/nanogui/ext/eigen/doc/AsciiQuickReference.txt +++ /dev/null @@ -1,207 +0,0 @@ -// A simple quickref for Eigen.

For example, the \link DenseBase::block() block(...) \endlink - methods are in \c %DenseBase. - -\section TopicClassHierarchyBaseClasses Base classes - -These classes serve as base classes for the five core classes mentioned above. They are more internal and so -less interesting for users of the Eigen library. - - - PlainObjectBase means dense (matrix or array) plain object, i.e. something that stores its own dense - array of coefficients. This is where, for instance, the \link PlainObjectBase::resize() resize() \endlink - methods go. \c %PlainObjectBase is inherited by \c %Matrix and by \c %Array. But above, we said that - \c %Matrix inherits \c %MatrixBase and \c %Array inherits \c %ArrayBase. So does that mean multiple - inheritance? No, because \c %PlainObjectBase \e itself inherits \c %MatrixBase or \c %ArrayBase depending - on whether we are in the matrix or array case. When we said above that \c %Matrix inherited - \c %MatrixBase, we omitted to say it does so indirectly via \c %PlainObjectBase. Same for \c %Array. - - DenseCoeffsBase means something that has dense coefficient accessors. It is a base class for - \c %DenseBase. The reason for \c %DenseCoeffsBase to exist is that the set of available coefficient - accessors is very different depending on whether a dense expression has direct memory access or not (the - \c DirectAccessBit flag). For example, if \c x is a plain matrix, then \c x has direct access, and - \c x.transpose() and \c x.block(...) also have direct access, because their coefficients can be read right - off memory, but for example, \c x+x does not have direct memory access, because obtaining any of its - coefficients requires a computation (an addition), it can't be just read off memory. - - EigenBase means anything that can be evaluated into a plain dense matrix or array (even if that would - be a bad idea). \c %EigenBase is really the absolute base class for anything that remotely looks like a - matrix or array. It is a base class for \c %DenseCoeffsBase, so it sits below all our dense class - hierarchy, but it is not limited to dense expressions. For example, \c %EigenBase is also inherited by - diagonal matrices, sparse matrices, etc... - - -\section TopicClassHierarchyInheritanceDiagrams Inheritance diagrams - -The inheritance diagram for Matrix looks as follows: - -

- %DenseBase Example

-Prints a sub-block of the dense expression. Accepts any dense matrix or array expression, but no sparse objects and no special matrix classes such as DiagonalMatrix. -\code -template -void print_block(const DenseBase& b, int x, int y, int r, int c) -{ - std::cout << "block: " << b.block(x,y,r,c) << std::endl; -} -\endcode - %ArrayBase Example

-Calculate the Euclidean distance between two points. -\code -template -typename DerivedA::Scalar squaredist(const MatrixBase& p1,const MatrixBase& p2) -{ - return (p1-p2).squaredNorm(); -} -\endcode -Notice that we used two template parameters, one per argument. This permits the function to handle inputs of different types, e.g., -\code -squaredist(v1,2*v2) -\endcode -where the first argument \c v1 is a vector and the second argument \c 2*v2 is an expression. -

- -These examples are just intended to give the reader a first impression of how functions can be written which take a plain and constant Matrix or Array argument. They are also intended to give the reader an idea about the most common base classes being the optimal candidates for functions. In the next section we will look in more detail at an example and the different ways it can be implemented, while discussing each implementation's problems and advantages. For the discussion below, Matrix and Array as well as MatrixBase and ArrayBase can be exchanged and all arguments still hold. - - -\section TopicUsingRefClass How to write generic, but non-templated function? - -In all the previous examples, the functions had to be template functions. This approach allows to write very generic code, but it is often desirable to write non templated function and still keep some level of genericity to avoid stupid copies of the arguments. The typical example is to write functions accepting both a MatrixXf or a block of a MatrixXf. This exactly the purpose of the Ref class. Here is a simple example: - - - - -
Example:Output:
-\include function_taking_ref.cpp - -\verbinclude function_taking_ref.out -
-In the first two calls to inv_cond, no copy occur because the memory layout of the arguments matches the memory layout accepted by Ref. However, in the last call, we have a generic expression that will be automatically evaluated into a temporary MatrixXf by the Ref<> object. - -A Ref object can also be writable. Here is an example of a function computing the covariance matrix of two input matrices where each row is an observation: -\code -void cov(const Ref x, const Ref y, Ref C) -{ - const float num_observations = static_cast(x.rows()); - const RowVectorXf x_mean = x.colwise().sum() / num_observations; - const RowVectorXf y_mean = y.colwise().sum() / num_observations; - C = (x.rowwise() - x_mean).transpose() * (y.rowwise() - y_mean) / num_observations; -} -\endcode -and here are two examples calling cov without any copy: -\code -MatrixXf m1, m2, m3 -cov(m1, m2, m3); -cov(m1.leftCols<3>(), m2.leftCols<3>(), m3.topLeftCorner<3,3>()); -\endcode -The Ref<> class has two other optional template arguments allowing to control the kind of memory layout that can be accepted without any copy. See the class Ref documentation for the details. - -\section TopicPlainFunctionsWorking In which cases do functions taking plain Matrix or Array arguments work? - -Without using template functions, and without the Ref class, a naive implementation of the previous cov function might look like this -\code -MatrixXf cov(const MatrixXf& x, const MatrixXf& y) -{ - const float num_observations = static_cast(x.rows()); - const RowVectorXf x_mean = x.colwise().sum() / num_observations; - const RowVectorXf y_mean = y.colwise().sum() / num_observations; - return (x.rowwise() - x_mean).transpose() * (y.rowwise() - y_mean) / num_observations; -} -\endcode -and contrary to what one might think at first, this implementation is fine unless you require a generic implementation that works with double matrices too and unless you do not care about temporary objects. Why is that the case? Where are temporaries involved? How can code as given below compile? -\code -MatrixXf x,y,z; -MatrixXf C = cov(x,y+z); -\endcode -In this special case, the example is fine and will be working because both parameters are declared as \e const references. The compiler creates a temporary and evaluates the expression x+z into this temporary. Once the function is processed, the temporary is released and the result is assigned to C. - -\b Note: Functions taking \e const references to Matrix (or Array) can process expressions at the cost of temporaries. - - -\section TopicPlainFunctionsFailing In which cases do functions taking a plain Matrix or Array argument fail? - -Here, we consider a slightly modified version of the function given above. This time, we do not want to return the result but pass an additional non-const paramter which allows us to store the result. A first naive implementation might look as follows. -\code -// Note: This code is flawed! -void cov(const MatrixXf& x, const MatrixXf& y, MatrixXf& C) -{ - const float num_observations = static_cast(x.rows()); - const RowVectorXf x_mean = x.colwise().sum() / num_observations; - const RowVectorXf y_mean = y.colwise().sum() / num_observations; - C = (x.rowwise() - x_mean).transpose() * (y.rowwise() - y_mean) / num_observations; -} -\endcode -When trying to execute the following code -\code -MatrixXf C = MatrixXf::Zero(3,6); -cov(x,y, C.block(0,0,3,3)); -\endcode -the compiler will fail, because it is not possible to convert the expression returned by \c MatrixXf::block() into a non-const \c MatrixXf&. This is the case because the compiler wants to protect you from writing your result to a temporary object. In this special case this protection is not intended -- we want to write to a temporary object. So how can we overcome this problem? - -The solution which is preferred at the moment is based on a little \em hack.

\code -m1.noalias() += s1 * (m2 * m3); \endcodeThis is a special feature of Eigen. Here the product between a scalar - and a matrix product does not evaluate the matrix product but instead it - returns a matrix product expression tracking the scalar scaling factor.
- Without this optimization, the matrix product would be evaluated into a - temporary as in the next example.

So before starting, let us explain what is nontrivial in compiling it correctly -- that is, producing optimized code -- so that the complexity of Eigen, that we'll explain here, is really useful. - -Look at the line of code -\code - u = v + w; // (*) -\endcode - -The first important thing about compiling it, is that the arrays should be traversed only once, like -\code - for(int i = 0; i < size; i++) u[i] = v[i] + w[i]; -\endcode -The problem is that if we make a naive C++ library where the VectorXf class has an operator+ returning a VectorXf, then the line of code (*) will amount to: -\code - VectorXf tmp = v + w; - VectorXf u = tmp; -\endcode -Obviously, the introduction of the temporary \a tmp here is useless. It has a very bad effect on performance, first because the creation of \a tmp requires a dynamic memory allocation in this context, and second as there are now two for loops: -\code - for(int i = 0; i < size; i++) tmp[i] = v[i] + w[i]; - for(int i = 0; i < size; i++) u[i] = tmp[i]; -\endcode -Traversing the arrays twice instead of once is terrible for performance, as it means that we do many redundant memory accesses. - -The second important thing about compiling the above program, is to make correct use of SSE2 instructions. Notice that Eigen also supports AltiVec and that all the discussion that we make here applies also to AltiVec. - -SSE2, like AltiVec, is a set of instructions allowing to perform computations on packets of 128 bits at once. Since a float is 32 bits, this means that SSE2 instructions can handle 4 floats at once. This means that, if correctly used, they can make our computation go up to 4x faster. - -However, in the above program, we have chosen size=50, so our vectors consist of 50 float's, and 50 is not a multiple of 4. This means that we cannot hope to do all of that computation using SSE2 instructions. The second best thing, to which we should aim, is to handle the 48 first coefficients with SSE2 instructions, since 48 is the biggest multiple of 4 below 50, and then handle separately, without SSE2, the 49th and 50th coefficients. Something like this: - -\code - for(int i = 0; i < 4*(size/4); i+=4) u.packet(i) = v.packet(i) + w.packet(i); - for(int i = 4*(size/4); i < size; i++) u[i] = v[i] + w[i]; -\endcode - -So let us look line by line at our example program, and let's follow Eigen as it compiles it. - -\section ConstructingVectors Constructing vectors - -Let's analyze the first line: - -\code - Eigen::VectorXf u(size), v(size), w(size); -\endcode - -First of all, VectorXf is the following typedef: -\code - typedef Matrix VectorXf; -\endcode - -The class template Matrix is declared in src/Core/util/ForwardDeclarations.h with 6 template parameters, but the last 3 are automatically determined by the first 3. So you don't need to worry about them for now. Here, Matrix\ means a matrix of floats, with a dynamic number of rows and 1 column. - -The Matrix class inherits a base class, MatrixBase. Don't worry about it, for now it suffices to say that MatrixBase is what unifies matrices/vectors and all the expressions types -- more on that below. - -When we do -\code - Eigen::VectorXf u(size); -\endcode -the constructor that is called is Matrix::Matrix(int), in src/Core/Matrix.h. Besides some assertions, all it does is to construct the \a m_storage member, which is of type DenseStorage\. - -You may wonder, isn't it overengineering to have the storage in a separate class? The reason is that the Matrix class template covers all kinds of matrices and vector: both fixed-size and dynamic-size. The storage method is not the same in these two cases. For fixed-size, the matrix coefficients are stored as a plain member array. For dynamic-size, the coefficients will be stored as a pointer to a dynamically-allocated array. Because of this, we need to abstract storage away from the Matrix class. That's DenseStorage. - -Let's look at this constructor, in src/Core/DenseStorage.h. You can see that there are many partial template specializations of DenseStorages here, treating separately the cases where dimensions are Dynamic or fixed at compile-time. The partial specialization that we are looking at is: -\code -template class DenseStorage -\endcode - -Here, the constructor called is DenseStorage::DenseStorage(int size, int rows, int columns) -with size=50, rows=50, columns=1. - -Here is this constructor: -\code -inline DenseStorage(int size, int rows, int) : m_data(internal::aligned_new(size)), m_rows(rows) {} -\endcode - -Here, the \a m_data member is the actual array of coefficients of the matrix. As you see, it is dynamically allocated. Rather than calling new[] or malloc(), as you can see, we have our own internal::aligned_new defined in src/Core/util/Memory.h. What it does is that if vectorization is enabled, then it uses a platform-specific call to allocate a 128-bit-aligned array, as that is very useful for vectorization with both SSE2 and AltiVec. If vectorization is disabled, it amounts to the standard new[]. - -As you can see, the constructor also sets the \a m_rows member to \a size. Notice that there is no \a m_columns member: indeed, in this partial specialization of DenseStorage, we know the number of columns at compile-time, since the _Cols template parameter is different from Dynamic. Namely, in our case, _Cols is 1, which is to say that our vector is just a matrix with 1 column. Hence, there is no need to store the number of columns as a runtime variable. - -When you call VectorXf::data() to get the pointer to the array of coefficients, it returns DenseStorage::data() which returns the \a m_data member. - -When you call VectorXf::size() to get the size of the vector, this is actually a method in the base class MatrixBase. It determines that the vector is a column-vector, since ColsAtCompileTime==1 (this comes from the template parameters in the typedef VectorXf). It deduces that the size is the number of rows, so it returns VectorXf::rows(), which returns DenseStorage::rows(), which returns the \a m_rows member, which was set to \a size by the constructor. - -\section ConstructionOfSumXpr Construction of the sum expression - -Now that our vectors are constructed, let's move on to the next line: - -\code -u = v + w; -\endcode - -The executive summary is that operator+ returns a "sum of vectors" expression, but doesn't actually perform the computation. It is the operator=, whose call occurs thereafter, that does the computation. - -Let us now see what Eigen does when it sees this: - -\code -v + w -\endcode - -Here, v and w are of type VectorXf, which is a typedef for a specialization of Matrix (as we explained above), which is a subclass of MatrixBase. So what is being called is - -\code -MatrixBase::operator+(const MatrixBase&) -\endcode - -The return type of this operator is -\code -CwiseBinaryOp, VectorXf, VectorXf> -\endcode -The CwiseBinaryOp class is our first encounter with an expression template. As we said, the operator+ doesn't by itself perform any computation, it just returns an abstract "sum of vectors" expression. Since there are also "difference of vectors" and "coefficient-wise product of vectors" expressions, we unify them all as "coefficient-wise binary operations", which we abbreviate as "CwiseBinaryOp". "Coefficient-wise" means that the operations is performed coefficient by coefficient. "binary" means that there are two operands -- we are adding two vectors with one another. - -Now you might ask, what if we did something like - -\code -v + w + u; -\endcode - -The first v + w would return a CwiseBinaryOp as above, so in order for this to compile, we'd need to define an operator+ also in the class CwiseBinaryOp... at this point it starts looking like a nightmare: are we going to have to define all operators in each of the expression classes (as you guessed, CwiseBinaryOp is only one of many) ? This looks like a dead end! - -The solution is that CwiseBinaryOp itself, as well as Matrix and all the other expression types, is a subclass of MatrixBase. So it is enough to define once and for all the operators in class MatrixBase. - -Since MatrixBase is the common base class of different subclasses, the aspects that depend on the subclass must be abstracted from MatrixBase. This is called polymorphism. - -The classical approach to polymorphism in C++ is by means of virtual functions. This is dynamic polymorphism. Here we don't want dynamic polymorphism because the whole design of Eigen is based around the assumption that all the complexity, all the abstraction, gets resolved at compile-time. This is crucial: if the abstraction can't get resolved at compile-time, Eigen's compile-time optimization mechanisms become useless, not to mention that if that abstraction has to be resolved at runtime it'll incur an overhead by itself. - -Here, what we want is to have a single class MatrixBase as the base of many subclasses, in such a way that each MatrixBase object (be it a matrix, or vector, or any kind of expression) knows at compile-time (as opposed to run-time) of which particular subclass it is an object (i.e. whether it is a matrix, or an expression, and what kind of expression). - -The solution is the Curiously Recurring Template Pattern. Let's do the break now. Hopefully you can read this wikipedia page during the break if needed, but it won't be allowed during the exam. - -In short, MatrixBase takes a template parameter \a Derived. Whenever we define a subclass Subclass, we actually make Subclass inherit MatrixBase\. The point is that different subclasses inherit different MatrixBase types. Thanks to this, whenever we have an object of a subclass, and we call on it some MatrixBase method, we still remember even from inside the MatrixBase method which particular subclass we're talking about. - -This means that we can put almost all the methods and operators in the base class MatrixBase, and have only the bare minimum in the subclasses. If you look at the subclasses in Eigen, like for instance the CwiseBinaryOp class, they have very few methods. There are coeff() and sometimes coeffRef() methods for access to the coefficients, there are rows() and cols() methods returning the number of rows and columns, but there isn't much more than that. All the meat is in MatrixBase, so it only needs to be coded once for all kinds of expressions, matrices, and vectors. - -So let's end this digression and come back to the piece of code from our example program that we were currently analyzing, - -\code -v + w -\endcode - -Now that MatrixBase is a good friend, let's write fully the prototype of the operator+ that gets called here (this code is from src/Core/MatrixBase.h): - -\code -template -class MatrixBase -{ - // ... - - template - const CwiseBinaryOp::Scalar>, Derived, OtherDerived> - operator+(const MatrixBase &other) const; - - // ... -}; -\endcode - -Here of course, \a Derived and \a OtherDerived are VectorXf. - -As we said, CwiseBinaryOp is also used for other operations such as substration, so it takes another template parameter determining the operation that will be applied to coefficients. This template parameter is a functor, that is, a class in which we have an operator() so it behaves like a function. Here, the functor used is internal::scalar_sum_op. It is defined in src/Core/Functors.h. - -Let us now explain the internal::traits here. The internal::scalar_sum_op class takes one template parameter: the type of the numbers to handle. Here of course we want to pass the scalar type (a.k.a. numeric type) of VectorXf, which is \c float. How do we determine which is the scalar type of \a Derived ? Throughout Eigen, all matrix and expression types define a typedef \a Scalar which gives its scalar type. For example, VectorXf::Scalar is a typedef for \c float. So here, if life was easy, we could find the numeric type of \a Derived as just -\code -typename Derived::Scalar -\endcode -Unfortunately, we can't do that here, as the compiler would complain that the type Derived hasn't yet been defined. So we use a workaround: in src/Core/util/ForwardDeclarations.h, we declared (not defined!) all our subclasses, like Matrix, and we also declared the following class template: -\code -template struct internal::traits; -\endcode -In src/Core/Matrix.h, right \em before the definition of class Matrix, we define a partial specialization of internal::traits for T=Matrix\. In this specialization of internal::traits, we define the Scalar typedef. So when we actually define Matrix, it is legal to refer to "typename internal::traits\::Scalar". - -Anyway, we have declared our operator+. In our case, where \a Derived and \a OtherDerived are VectorXf, the above declaration amounts to: -\code -class MatrixBase -{ - // ... - - const CwiseBinaryOp, VectorXf, VectorXf> - operator+(const MatrixBase &other) const; - - // ... -}; -\endcode - -Let's now jump to src/Core/CwiseBinaryOp.h to see how it is defined. As you can see there, all it does is to return a CwiseBinaryOp object, and this object is just storing references to the left-hand-side and right-hand-side expressions -- here, these are the vectors \a v and \a w. Well, the CwiseBinaryOp object is also storing an instance of the (empty) functor class, but you shouldn't worry about it as that is a minor implementation detail. - -Thus, the operator+ hasn't performed any actual computation. To summarize, the operation \a v + \a w just returned an object of type CwiseBinaryOp which did nothing else than just storing references to \a v and \a w. - -\section Assignment The assignment - -At this point, the expression \a v + \a w has finished evaluating, so, in the process of compiling the line of code -\code -u = v + w; -\endcode -we now enter the operator=. - -What operator= is being called here? The vector u is an object of class VectorXf, i.e. Matrix. In src/Core/Matrix.h, inside the definition of class Matrix, we see this: -\code - template - inline Matrix& operator=(const MatrixBase& other) - { - eigen_assert(m_storage.data()!=0 && "you cannot use operator= with a non initialized matrix (instead use set()"); - return Base::operator=(other.derived()); - } -\endcode -Here, Base is a typedef for MatrixBase\. So, what is being called is the operator= of MatrixBase. Let's see its prototype in src/Core/MatrixBase.h: -\code - template - Derived& operator=(const MatrixBase& other); -\endcode -Here, \a Derived is VectorXf (since u is a VectorXf) and \a OtherDerived is CwiseBinaryOp. More specifically, as explained in the previous section, \a OtherDerived is: -\code -CwiseBinaryOp, VectorXf, VectorXf> -\endcode -So the full prototype of the operator= being called is: -\code -VectorXf& MatrixBase::operator=(const MatrixBase, VectorXf, VectorXf> > & other); -\endcode -This operator= literally reads "copying a sum of two VectorXf's into another VectorXf". - -Let's now look at the implementation of this operator=. It resides in the file src/Core/Assign.h. - -What we can see there is: -\code -template -template -inline Derived& MatrixBase - ::operator=(const MatrixBase& other) -{ - return internal::assign_selector::run(derived(), other.derived()); -} -\endcode - -OK so our next task is to understand internal::assign_selector :) - -Here is its declaration (all that is still in the same file src/Core/Assign.h) -\code -template -struct internal::assign_selector; -\endcode - -So internal::assign_selector takes 4 template parameters, but the 2 last ones are automatically determined by the 2 first ones. - -EvalBeforeAssigning is here to enforce the EvalBeforeAssigningBit. As explained here, certain expressions have this flag which makes them automatically evaluate into temporaries before assigning them to another expression. This is the case of the Product expression, in order to avoid strange aliasing effects when doing "m = m * m;" However, of course here our CwiseBinaryOp expression doesn't have the EvalBeforeAssigningBit: we said since the beginning that we didn't want a temporary to be introduced here. So if you go to src/Core/CwiseBinaryOp.h, you'll see that the Flags in internal::traits\ don't include the EvalBeforeAssigningBit. The Flags member of CwiseBinaryOp is then imported from the internal::traits by the EIGEN_GENERIC_PUBLIC_INTERFACE macro. Anyway, here the template parameter EvalBeforeAssigning has the value \c false. - -NeedToTranspose is here for the case where the user wants to copy a row-vector into a column-vector. We allow this as a special exception to the general rule that in assignments we require the dimesions to match. Anyway, here both the left-hand and right-hand sides are column vectors, in the sense that ColsAtCompileTime is equal to 1. So NeedToTranspose is \c false too. - -So, here we are in the partial specialization: -\code -internal::assign_selector -\endcode - -Here's how it is defined: -\code -template -struct internal::assign_selector { - static Derived& run(Derived& dst, const OtherDerived& other) { return dst.lazyAssign(other.derived()); } -}; -\endcode - -OK so now our next job is to understand how lazyAssign works :) - -\code -template -template -inline Derived& MatrixBase - ::lazyAssign(const MatrixBase& other) -{ - EIGEN_STATIC_ASSERT_SAME_MATRIX_SIZE(Derived,OtherDerived) - eigen_assert(rows() == other.rows() && cols() == other.cols()); - internal::assign_impl::run(derived(),other.derived()); - return derived(); -} -\endcode - -What do we see here? Some assertions, and then the only interesting line is: -\code - internal::assign_impl::run(derived(),other.derived()); -\endcode - -OK so now we want to know what is inside internal::assign_impl. - -Here is its declaration: -\code -template::Vectorization, - int Unrolling = internal::assign_traits::Unrolling> -struct internal::assign_impl; -\endcode -Again, internal::assign_selector takes 4 template parameters, but the 2 last ones are automatically determined by the 2 first ones. - -These two parameters \a Vectorization and \a Unrolling are determined by a helper class internal::assign_traits. Its job is to determine which vectorization strategy to use (that is \a Vectorization) and which unrolling strategy to use (that is \a Unrolling). - -We'll not enter into the details of how these strategies are chosen (this is in the implementation of internal::assign_traits at the top of the same file). Let's just say that here \a Vectorization has the value \a LinearVectorization, and \a Unrolling has the value \a NoUnrolling (the latter is obvious since our vectors have dynamic size so there's no way to unroll the loop at compile-time). - -So the partial specialization of internal::assign_impl that we're looking at is: -\code -internal::assign_impl -\endcode - -Here is how it's defined: -\code -template -struct internal::assign_impl -{ - static void run(Derived1 &dst, const Derived2 &src) - { - const int size = dst.size(); - const int packetSize = internal::packet_traits::size; - const int alignedStart = internal::assign_traits::DstIsAligned ? 0 - : internal::first_aligned(&dst.coeffRef(0), size); - const int alignedEnd = alignedStart + ((size-alignedStart)/packetSize)*packetSize; - - for(int index = 0; index < alignedStart; index++) - dst.copyCoeff(index, src); - - for(int index = alignedStart; index < alignedEnd; index += packetSize) - { - dst.template copyPacket::SrcAlignment>(index, src); - } - - for(int index = alignedEnd; index < size; index++) - dst.copyCoeff(index, src); - } -}; -\endcode - -Here's how it works. \a LinearVectorization means that the left-hand and right-hand side expression can be accessed linearly i.e. you can refer to their coefficients by one integer \a index, as opposed to having to refer to its coefficients by two integers \a row, \a column. - -As we said at the beginning, vectorization works with blocks of 4 floats. Here, \a PacketSize is 4. - -There are two potential problems that we need to deal with: -\li first, vectorization works much better if the packets are 128-bit-aligned. This is especially important for write access. So when writing to the coefficients of \a dst, we want to group these coefficients by packets of 4 such that each of these packets is 128-bit-aligned. In general, this requires to skip a few coefficients at the beginning of \a dst. This is the purpose of \a alignedStart. We then copy these first few coefficients one by one, not by packets. However, in our case, the \a dst expression is a VectorXf and remember that in the construction of the vectors we allocated aligned arrays. Thanks to \a DstIsAligned, Eigen remembers that without having to do any runtime check, so \a alignedStart is zero and this part is avoided altogether. -\li second, the number of coefficients to copy is not in general a multiple of \a packetSize. Here, there are 50 coefficients to copy and \a packetSize is 4. So we'll have to copy the last 2 coefficients one by one, not by packets. Here, \a alignedEnd is 48. - -Now come the actual loops. - -First, the vectorized part: the 48 first coefficients out of 50 will be copied by packets of 4: -\code - for(int index = alignedStart; index < alignedEnd; index += packetSize) - { - dst.template copyPacket::SrcAlignment>(index, src); - } -\endcode - -What is copyPacket? It is defined in src/Core/Coeffs.h: -\code -template -template -inline void MatrixBase::copyPacket(int index, const MatrixBase& other) -{ - eigen_internal_assert(index >= 0 && index < size()); - derived().template writePacket(index, - other.derived().template packet(index)); -} -\endcode - -OK, what are writePacket() and packet() here? - -First, writePacket() here is a method on the left-hand side VectorXf. So we go to src/Core/Matrix.h to look at its definition: -\code -template -inline void writePacket(int index, const PacketScalar& x) -{ - internal::pstoret(m_storage.data() + index, x); -} -\endcode -Here, \a StoreMode is \a #Aligned, indicating that we are doing a 128-bit-aligned write access, \a PacketScalar is a type representing a "SSE packet of 4 floats" and internal::pstoret is a function writing such a packet in memory. Their definitions are architecture-specific, we find them in src/Core/arch/SSE/PacketMath.h: - -The line in src/Core/arch/SSE/PacketMath.h that determines the PacketScalar type (via a typedef in Matrix.h) is: -\code -template<> struct internal::packet_traits { typedef __m128 type; enum {size=4}; }; -\endcode -Here, __m128 is a SSE-specific type. Notice that the enum \a size here is what was used to define \a packetSize above. - -And here is the implementation of internal::pstoret: -\code -template<> inline void internal::pstore(float* to, const __m128& from) { _mm_store_ps(to, from); } -\endcode -Here, __mm_store_ps is a SSE-specific intrinsic function, representing a single SSE instruction. The difference between internal::pstore and internal::pstoret is that internal::pstoret is a dispatcher handling both the aligned and unaligned cases, you find its definition in src/Core/GenericPacketMath.h: -\code -template -inline void internal::pstoret(Scalar* to, const Packet& from) -{ - if(LoadMode == Aligned) - internal::pstore(to, from); - else - internal::pstoreu(to, from); -} -\endcode - -OK, that explains how writePacket() works. Now let's look into the packet() call. Remember that we are analyzing this line of code inside copyPacket(): -\code -derived().template writePacket(index, - other.derived().template packet(index)); -\endcode - -Here, \a other is our sum expression \a v + \a w. The .derived() is just casting from MatrixBase to the subclass which here is CwiseBinaryOp. So let's go to src/Core/CwiseBinaryOp.h: -\code -class CwiseBinaryOp -{ - // ... - template - inline PacketScalar packet(int index) const - { - return m_functor.packetOp(m_lhs.template packet(index), m_rhs.template packet(index)); - } -}; -\endcode -Here, \a m_lhs is the vector \a v, and \a m_rhs is the vector \a w. So the packet() function here is Matrix::packet(). The template parameter \a LoadMode is \a #Aligned. So we're looking at -\code -class Matrix -{ - // ... - template - inline PacketScalar packet(int index) const - { - return internal::ploadt(m_storage.data() + index); - } -}; -\endcode -We let you look up the definition of internal::ploadt in GenericPacketMath.h and the internal::pload in src/Core/arch/SSE/PacketMath.h. It is very similar to the above for internal::pstore. - -Let's go back to CwiseBinaryOp::packet(). Once the packets from the vectors \a v and \a w have been returned, what does this function do? It calls m_functor.packetOp() on them. What is m_functor? Here we must remember what particular template specialization of CwiseBinaryOp we're dealing with: -\code -CwiseBinaryOp, VectorXf, VectorXf> -\endcode -So m_functor is an object of the empty class internal::scalar_sum_op. As we mentioned above, don't worry about why we constructed an object of this empty class at all -- it's an implementation detail, the point is that some other functors need to store member data. - -Anyway, internal::scalar_sum_op is defined in src/Core/Functors.h: -\code -template struct internal::scalar_sum_op EIGEN_EMPTY_STRUCT { - inline const Scalar operator() (const Scalar& a, const Scalar& b) const { return a + b; } - template - inline const PacketScalar packetOp(const PacketScalar& a, const PacketScalar& b) const - { return internal::padd(a,b); } -}; -\endcode -As you can see, all what packetOp() does is to call internal::padd on the two packets. Here is the definition of internal::padd from src/Core/arch/SSE/PacketMath.h: -\code -template<> inline __m128 internal::padd(const __m128& a, const __m128& b) { return _mm_add_ps(a,b); } -\endcode -Here, _mm_add_ps is a SSE-specific intrinsic function, representing a single SSE instruction. - -To summarize, the loop -\code - for(int index = alignedStart; index < alignedEnd; index += packetSize) - { - dst.template copyPacket::SrcAlignment>(index, src); - } -\endcode -has been compiled to the following code: for \a index going from 0 to the 11 ( = 48/4 - 1), read the i-th packet (of 4 floats) from the vector v and the i-th packet from the vector w using two __mm_load_ps SSE instructions, then add them together using a __mm_add_ps instruction, then store the result using a __mm_store_ps instruction. - -There remains the second loop handling the last few (here, the last 2) coefficients: -\code - for(int index = alignedEnd; index < size; index++) - dst.copyCoeff(index, src); -\endcode -However, it works just like the one we just explained, it is just simpler because there is no SSE vectorization involved here. copyPacket() becomes copyCoeff(), packet() becomes coeff(), writePacket() becomes coeffRef(). If you followed us this far, you can probably understand this part by yourself. - -We see that all the C++ abstraction of Eigen goes away during compilation and that we indeed are precisely controlling which assembly instructions we emit. Such is the beauty of C++! Since we have such precise control over the emitted assembly instructions, but such complex logic to choose the right instructions, we can say that Eigen really behaves like an optimizing compiler. If you prefer, you could say that Eigen behaves like a script for the compiler. In a sense, C++ template metaprogramming is scripting the compiler -- and it's been shown that this scripting language is Turing-complete.

You can also read this page as the first part of the Tutorial, which explains the library in more detail; in this case you will continue with \ref TutorialMatrixClass. - -\section GettingStartedInstallation How to "install" Eigen? - -In order to use Eigen, you just need to download and extract Eigen's source code (see the wiki for download instructions). In fact, the header files in the \c Eigen subdirectory are the only files required to compile programs using Eigen. The header files are the same for all platforms. It is not necessary to use CMake or install anything. - - -\section GettingStartedFirstProgram A simple first program - -Here is a rather simple program to get you started. - -\include QuickStart_example.cpp - -We will explain the program after telling you how to compile it. - - -\section GettingStartedCompiling Compiling and running your first program - -There is no library to link to. The only thing that you need to keep in mind when compiling the above program is that the compiler must be able to find the Eigen header files. The directory in which you placed Eigen's source code must be in the include path. With GCC you use the -I option to achieve this, so you can compile the program with a command like this: - -\code g++ -I /path/to/eigen/ my_program.cpp -o my_program \endcode - -On Linux or Mac OS X, another option is to symlink or copy the Eigen folder into /usr/local/include/. This way, you can compile the program with: - -\code g++ my_program.cpp -o my_program \endcode - -When you run the program, it produces the following output: - -\include QuickStart_example.out - - -\section GettingStartedExplanation Explanation of the first program - -The Eigen header files define many types, but for simple applications it may be enough to use only the \c MatrixXd type. This represents a matrix of arbitrary size (hence the \c X in \c MatrixXd), in which every entry is a \c double (hence the \c d in \c MatrixXd). See the \ref QuickRef_Types "quick reference guide" for an overview of the different types you can use to represent a matrix. - -The \c Eigen/Dense header file defines all member functions for the MatrixXd type and related types (see also the \ref QuickRef_Headers "table of header files"). All classes and functions defined in this header file (and other Eigen header files) are in the \c Eigen namespace. - -The first line of the \c main function declares a variable of type \c MatrixXd and specifies that it is a matrix with 2 rows and 2 columns (the entries are not initialized). The statement m(0,0) = 3 sets the entry in the top-left corner to 3. You need to use round parentheses to refer to entries in the matrix. As usual in computer science, the index of the first index is 0, as opposed to the convention in mathematics that the first index is 1. - -The following three statements sets the other three entries. The final line outputs the matrix \c m to the standard output stream. - - -\section GettingStartedExample2 Example 2: Matrices and vectors - -Here is another example, which combines matrices with vectors. Concentrate on the left-hand program for now; we will talk about the right-hand program later. - - - - -
Size set at run time:Size set at compile time:
-\include QuickStart_example2_dynamic.cpp - -\include QuickStart_example2_fixed.cpp -
- -The output is as follows: - -\include QuickStart_example2_dynamic.out - - -\section GettingStartedExplanation2 Explanation of the second example - -The second example starts by declaring a 3-by-3 matrix \c m which is initialized using the \link DenseBase::Random(Index,Index) Random() \endlink method with random values between -1 and 1. The next line applies a linear mapping such that the values are between 10 and 110. The function call \link DenseBase::Constant(Index,Index,const Scalar&) MatrixXd::Constant\endlink(3,3,1.2) returns a 3-by-3 matrix expression having all coefficients equal to 1.2. The rest is standard arithmetics. - -The next line of the \c main function introduces a new type: \c VectorXd. This represents a (column) vector of arbitrary size. Here, the vector \c v is created to contain \c 3 coefficients which are left unitialized. The one but last line uses the so-called comma-initializer, explained in \ref TutorialAdvancedInitialization, to set all coefficients of the vector \c v to be as follows: - -\f[ -v = -\begin{bmatrix} - 1 \\ - 2 \\ - 3 -\end{bmatrix}. -\f] - -The final line of the program multiplies the matrix \c m with the vector \c v and outputs the result. - -Now look back at the second example program. We presented two versions of it. In the version in the left column, the matrix is of type \c MatrixXd which represents matrices of arbitrary size. The version in the right column is similar, except that the matrix is of type \c Matrix3d, which represents matrices of a fixed size (here 3-by-3). Because the type already encodes the size of the matrix, it is not necessary to specify the size in the constructor; compare MatrixXd m(3,3) with Matrix3d m. Similarly, we have \c VectorXd on the left (arbitrary size) versus \c Vector3d on the right (fixed size). Note that here the coefficients of vector \c v are directly set in the constructor, though the same syntax of the left example could be used too. - -The use of fixed-size matrices and vectors has two advantages. The compiler emits better (faster) code because it knows the size of the matrices and vectors. Specifying the size in the type also allows for more rigorous checking at compile-time. For instance, the compiler will complain if you try to multiply a \c Matrix4d (a 4-by-4 matrix) with a \c Vector3d (a vector of size 3). However, the use of many types increases compilation time and the size of the executable. The size of the matrix may also not be known at compile-time. A rule of thumb is to use fixed-size matrices for size 4-by-4 and smaller. - - -\section GettingStartedConclusion Where to go from here? - -It's worth taking the time to read the \ref TutorialMatrixClass "long tutorial". - -However if you think you don't need it, you can directly use the classes documentation and our \ref QuickRefPage. - -\li \b Next: \ref TutorialMatrixClass - -*/ - -} - diff --git a/testbed/nanogui/ext/eigen/doc/SparseLinearSystems.dox b/testbed/nanogui/ext/eigen/doc/SparseLinearSystems.dox deleted file mode 100644 index c00be10d..00000000 --- a/testbed/nanogui/ext/eigen/doc/SparseLinearSystems.dox +++ /dev/null @@ -1,183 +0,0 @@ -namespace Eigen { -/** \eigenManualPage TopicSparseSystems Solving Sparse Linear Systems -In Eigen, there are several methods available to solve linear systems when the coefficient matrix is sparse.

The opposite triangle might either be empty or contain arbitrary values. - -In the case where multiple problems with the same sparsity pattern have to be solved, then the "compute" step can be decomposed as follow: -\code -SolverClassName > solver; -solver.analyzePattern(A); // for this step the numerical values of A are not used -solver.factorize(A); -x1 = solver.solve(b1); -x2 = solver.solve(b2); -... -A = ...; // modify the values of the nonzeros of A, the nonzeros pattern must stay unchanged -solver.factorize(A); -x1 = solver.solve(b1); -x2 = solver.solve(b2); -... -\endcode -The compute() method is equivalent to calling both analyzePattern() and factorize(). - -Finally, each solver provides some specific features, such as determinant, access to the factors, controls of the iterations, and so on. -More details are availble in the documentations of the respective classes. - -\section TheSparseCompute The Compute Step -In the compute() function, the matrix is generally factorized: LLT for self-adjoint matrices, LDLT for general hermitian matrices, LU for non hermitian matrices and QR for rectangular matrices. These are the results of using direct solvers. For this class of solvers precisely, the compute step is further subdivided into analyzePattern() and factorize(). - -The goal of analyzePattern() is to reorder the nonzero elements of the matrix, such that the factorization step creates less fill-in. This step exploits only the structure of the matrix. Hence, the results of this step can be used for other linear systems where the matrix has the same structure. Note however that sometimes, some external solvers (like SuperLU) require that the values of the matrix are set in this step, for instance to equilibrate the rows and columns of the matrix. In this situation, the results of this step should not be used with other matrices. - -Eigen provides a limited set of methods to reorder the matrix in this step, either built-in (COLAMD, AMD) or external (METIS). These methods are set in template parameter list of the solver : -\code -DirectSolverClassName, OrderingMethod > solver; -\endcode - -See the \link OrderingMethods_Module OrderingMethods module \endlink for the list of available methods and the associated options. - -In factorize(), the factors of the coefficient matrix are computed. This step should be called each time the values of the matrix change. However, the structural pattern of the matrix should not change between multiple calls. - -For iterative solvers, the compute step is used to eventually setup a preconditioner. For instance, with the ILUT preconditioner, the incomplete factors L and U are computed in this step. Remember that, basically, the goal of the preconditioner is to speedup the convergence of an iterative method by solving a modified linear system where the coefficient matrix has more clustered eigenvalues. For real problems, an iterative solver should always be used with a preconditioner. In Eigen, a preconditioner is selected by simply adding it as a template parameter to the iterative solver object. -\code -IterativeSolverClassName, PreconditionerName > solver; -\endcode -The member function preconditioner() returns a read-write reference to the preconditioner - to directly interact with it. See the \link IterativeLinearSolvers_Module Iterative solvers module \endlink and the documentation of each class for the list of available methods. - -\section TheSparseSolve The Solve step -The solve() function computes the solution of the linear systems with one or many right hand sides. -\code -X = solver.solve(B); -\endcode -Here, B can be a vector or a matrix where the columns form the different right hand sides. The solve() function can be called several times as well, for instance when all the right hand sides are not available at once. -\code -x1 = solver.solve(b1); -// Get the second right hand side b2 -x2 = solver.solve(b2); -// ... -\endcode -For direct methods, the solution are computed at the machine precision. Sometimes, the solution need not be too accurate. In this case, the iterative methods are more suitable and the desired accuracy can be set before the solve step using \b setTolerance(). For all the available functions, please, refer to the documentation of the \link IterativeLinearSolvers_Module Iterative solvers module \endlink. - -\section BenchmarkRoutine -Most of the time, all you need is to know how much time it will take to qolve your system, and hopefully, what is the most suitable solver. In Eigen, we provide a benchmark routine that can be used for this purpose. It is very easy to use. In the build directory, navigate to bench/spbench and compile the routine by typing \b make \e spbenchsolver. Run it with --help option to get the list of all available options. Basically, the matrices to test should be in MatrixMarket Coordinate format, and the routine returns the statistics from all available solvers in Eigen. - -The following table gives an example of XML statistics from several Eigen built-in and external solvers. - - -

Category Operations Notes
Constructor -\code - SparseMatrix sm1(1000,1000); - SparseMatrix,RowMajor> sm2; -\endcode - Default is ColMajor
Resize/Reserve - \code - sm1.resize(m,n); //Change sm1 to a m x n matrix. - sm1.reserve(nnz); // Allocate room for nnz nonzeros elements. - \endcode - Note that when calling reserve(), it is not required that nnz is the exact number of nonzero elements in the final matrix. However, an exact estimation will avoid multiple reallocations during the insertion phase.
Assignment -\code - SparseMatrix sm1; - // Initialize sm2 with sm1. - SparseMatrix sm2(sm1), sm3; - // Assignment and evaluations modify the storage order. - sm3 = sm1; - \endcode - The copy constructor can be used to convert from a storage order to another
Element-wise Insertion -\code -// Insert a new element; - sm1.insert(i, j) = v_ij; - -// Update the value v_ij - sm1.coeffRef(i,j) = v_ij; - sm1.coeffRef(i,j) += v_ij; - sm1.coeffRef(i,j) -= v_ij; -\endcode - insert() assumes that the element does not already exist; otherwise, use coeffRef()
Batch insertion -\code - std::vector< Eigen::Triplet > tripletList; - tripletList.reserve(estimation_of_entries); - // -- Fill tripletList with nonzero elements... - sm1.setFromTriplets(TripletList.begin(), TripletList.end()); -\endcode -A complete example is available at \link TutorialSparseFilling Triplet Insertion \endlink.
Constant or Random Insertion -\code -sm1.setZero(); -\endcode -Remove all non-zero coefficients

\code - sm1.rows(); // Number of rows - sm1.cols(); // Number of columns - sm1.nonZeros(); // Number of non zero values - sm1.outerSize(); // Number of columns (resp. rows) for a column major (resp. row major ) - sm1.innerSize(); // Number of rows (resp. columns) for a row major (resp. column major) - sm1.norm(); // Euclidian norm of the matrix - sm1.squaredNorm(); // Squared norm of the matrix - sm1.blueNorm(); - sm1.isVector(); // Check if sm1 is a sparse vector or a sparse matrix - sm1.isCompressed(); // Check if sm1 is in compressed form - ... - \endcode
- -\section SparseBasicOps Arithmetic operations -It is easy to perform arithmetic operations on sparse matrices provided that the dimensions are adequate and that the matrices have the same storage order. Note that the evaluation can always be done in a matrix with a different storage order.

As \ref TutorialMatrixClass explains, the %Matrix class template has six -template parameters, of which three are compulsory (\c Scalar, \c RowsAtCompileTime and \c ColsAtCompileTime) -and three are optional (\c Options, \c MaxRowsAtCompileTime and \c MaxColsAtCompileTime). If the \c Options -parameter is set to \c RowMajor, then the matrix or array is stored in row-major order; if it is set to -\c ColMajor, then it is stored in column-major order. This mechanism is used in the above Eigen program to -specify the storage order. - -If the storage order is not specified, then Eigen defaults to storing the entry in column-major. This is also -the case if one of the convenience typedefs (\c Matrix3f, \c ArrayXXd, etc.) is used. - -Matrices and arrays using one storage order can be assigned to matrices and arrays using the other storage -order, as happens in the above program when \c Arowmajor is initialized using \c Acolmajor. Eigen will reorder -the entries automatically. More generally, row-major and column-major matrices can be mixed in an expression -as we want. - - -\section TopicStorageOrdersWhich Which storage order to choose? - -So, which storage order should you use in your program? There is no simple answer to this question; it depends -on your application. Here are some points to keep in mind: - - - Your users may expect you to use a specific storage order. Alternatively, you may use other libraries than - Eigen, and these other libraries may expect a certain storage order. In these cases it may be easiest and - fastest to use this storage order in your whole program. - - Algorithms that traverse a matrix row by row will go faster when the matrix is stored in row-major order - because of better data locality. Similarly, column-by-column traversal is faster for column-major - matrices. It may be worthwhile to experiment a bit to find out what is faster for your particular - application. - - The default in Eigen is column-major. Naturally, most of the development and testing of the Eigen library - is thus done with column-major matrices. This means that, even though we aim to support column-major and - row-major storage orders transparently, the Eigen library may well work best with column-major matrices. - -*/ -} diff --git a/testbed/nanogui/ext/eigen/doc/StructHavingEigenMembers.dox b/testbed/nanogui/ext/eigen/doc/StructHavingEigenMembers.dox deleted file mode 100644 index 74a8d521..00000000 --- a/testbed/nanogui/ext/eigen/doc/StructHavingEigenMembers.dox +++ /dev/null @@ -1,190 +0,0 @@ -namespace Eigen { - -/** \eigenManualPage TopicStructHavingEigenMembers Structures Having Eigen Members - -\eigenAutoToc - -\section summary Executive Summary - -If you define a structure having members of \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen types", you must overload its "operator new" so that it generates 16-bytes-aligned pointers.

Which is exactly the size of a SSE packet, which makes it possible to use SSE for all sorts of operations on this vector. But SSE instructions (at least the ones that Eigen uses, which are the fast ones) require 128-bit alignment. Otherwise you get a segmentation fault. - -For this reason, Eigen takes care by itself to require 128-bit alignment for Eigen::Vector2d, by doing two things: -\li Eigen requires 128-bit alignment for the Eigen::Vector2d's array (of 2 doubles). With GCC, this is done with a __attribute__ ((aligned(16))). -\li Eigen overloads the "operator new" of Eigen::Vector2d so it will always return 128-bit aligned pointers. - -Thus, normally, you don't have to worry about anything, Eigen handles alignment for you... - -... except in one case. When you have a class Foo like above, and you dynamically allocate a new Foo as above, then, since Foo doesn't have aligned "operator new", the returned pointer foo is not necessarily 128-bit aligned. - -The alignment attribute of the member v is then relative to the start of the class, foo. If the foo pointer wasn't aligned, then foo->v won't be aligned either! - -The solution is to let class Foo have an aligned "operator new", as we showed in the previous section. - -\section movetotop Should I then put all the members of Eigen types at the beginning of my class? - -That's not required. Since Eigen takes care of declaring 128-bit alignment, all members that need it are automatically 128-bit aligned relatively to the class.

So they don't cause this issue. The issue discussed here is only with \ref TopicFixedSizeVectorizable "fixed-size vectorizable matrices and vectors". - -\section bugineigen So is this a bug in Eigen? - -No, it's not our bug. It's more like an inherent problem of the C++98 language specification, and seems to be taken care of in the upcoming language revision: see this document. - -\section conditional What if I want to do this conditionnally (depending on template parameters) ? - -For this situation, we offer the macro EIGEN_MAKE_ALIGNED_OPERATOR_NEW_IF(NeedsToAlign). It will generate aligned operators like EIGEN_MAKE_ALIGNED_OPERATOR_NEW if NeedsToAlign is true. It will generate operators with the default alignment if NeedsToAlign is false. - -Example: - -\code -template class Foo -{ - typedef Eigen::Matrix Vector; - enum { NeedsToAlign = (sizeof(Vector)%16)==0 }; - ... - Vector v; - ... -public: - EIGEN_MAKE_ALIGNED_OPERATOR_NEW_IF(NeedsToAlign) -}; - -... - -Foo<4> *foo4 = new Foo<4>; // foo4 is guaranteed to be 128bit-aligned -Foo<3> *foo3 = new Foo<3>; // foo3 has only the system default alignment guarantee -\endcode - - -\section othersolutions Other solutions - -In case putting the EIGEN_MAKE_ALIGNED_OPERATOR_NEW macro everywhere is too intrusive, there exists at least two other solutions. - -\subsection othersolutions1 Disabling alignment - -The first is to disable alignment requirement for the fixed size members: -\code -class Foo -{ - ... - Eigen::Matrix v; - ... -}; -\endcode -This has for effect to disable vectorization when using \c v. -If a function of Foo uses it several times, then it still possible to re-enable vectorization by copying it into an aligned temporary vector: -\code -void Foo::bar() -{ - Eigen::Vector2d av(v); - // use av instead of v - ... - // if av changed, then do: - v = av; -} -\endcode - -\subsection othersolutions2 Private structure - -The second consist in storing the fixed-size objects into a private struct which will be dynamically allocated at the construction time of the main object: - -\code -struct Foo_d -{ - EIGEN_MAKE_ALIGNED_OPERATOR_NEW - Vector2d v; - ... -}; - - -struct Foo { - Foo() { init_d(); } - ~Foo() { delete d; } - void bar() - { - // use d->v instead of v - ... - } -private: - void init_d() { d = new Foo_d; } - Foo_d* d; -}; -\endcode - -The clear advantage here is that the class Foo remains unchanged regarding alignment issues.

In fact, the compiler should choose the second -possibility, according to the standard. If dst.triangularPart is a member template (as in our case), -the programmer should specify this explicitly with the \c template keyword and write dst.template -triangularPart. - -The precise rules are rather complicated, but ignoring some subtleties we can summarize them as follows: -- A dependent name is name that depends (directly or indirectly) on a template parameter. In the - example, \c dst is a dependent name because it is of type MatrixBase<Derived1> which depends - on the template parameter \c Derived1. -- If the code contains either one of the contructions xxx.yyy or xxx->yyy and \c xxx is a - dependent name and \c yyy refers to a member template, then the \c template keyword must be used before - \c yyy, leading to xxx.template yyy or xxx->template yyy. -- If the code contains the contruction xxx::yyy and \c xxx is a dependent name and \c yyy refers to a - member typedef, then the \c typename keyword must be used before the whole construction, leading to - typename xxx::yyy. - -As an example where the \c typename keyword is required, consider the following code in \ref TutorialSparse -for iterating over the non-zero entries of a sparse matrix type: - -\code -SparseMatrixType mat(rows,cols); -for (int k=0; k -void iterateOverSparseMatrix(const SparseMatrix& mat; -{ - for (int k=0; k::InnerIterator it(mat,k); it; ++it) - { - /* ... */ - } -} -\endcode - - -\section TopicTemplateKeywordResources Resources for further reading - -For more information and a fuller explanation of this topic, the reader may consult the following sources: -- The book "C++ Template Metaprogramming" by David Abrahams and Aleksey Gurtovoy contains a very good - explanation in Appendix B ("The typename and template Keywords") which formed the basis for this page. -- http://pages.cs.wisc.edu/~driscoll/typename.html -- http://www.parashift.com/c++-faq-lite/templates.html#faq-35.18 -- http://www.comeaucomputing.com/techtalk/templates/#templateprefix -- http://www.comeaucomputing.com/techtalk/templates/#typename - -*/ -} diff --git a/testbed/nanogui/ext/eigen/doc/TopicAliasing.dox b/testbed/nanogui/ext/eigen/doc/TopicAliasing.dox deleted file mode 100644 index c2654aed..00000000 --- a/testbed/nanogui/ext/eigen/doc/TopicAliasing.dox +++ /dev/null @@ -1,215 +0,0 @@ -namespace Eigen { - -/** \eigenManualPage TopicAliasing Aliasing - -In %Eigen, aliasing refers to assignment statement in which the same matrix (or array or vector) appears on the -left and on the right of the assignment operators.

There are two problems with that: first, lazy evaluation is not always a good choice for performance; second, lazy evaluation can be very dangerous, for example with matrix products: doing matrix = matrix*matrix gives a wrong result if the matrix product is lazy-evaluated, because of the way matrix product works. - -For these reasons, Eigen has intelligent compile-time mechanisms to determine automatically when to use lazy evaluation, and when on the contrary it should evaluate immediately into a temporary variable. - -So in the basic example, - -\code matrix1 = matrix2 + matrix3; \endcode - -Eigen chooses lazy evaluation. Thus the arrays are traversed only once, producing optimized code. If you really want to force immediate evaluation, use \link MatrixBase::eval() eval()\endlink: - -\code matrix1 = (matrix2 + matrix3).eval(); \endcode - -Here is now a more involved example: - -\code matrix1 = -matrix2 + matrix3 + 5 * matrix4; \endcode - -Eigen chooses lazy evaluation at every stage in that example, which is clearly the correct choice. In fact, lazy evaluation is the "default choice" and Eigen will choose it except in a few circumstances. - -The first circumstance in which Eigen chooses immediate evaluation, is when it sees an assignment a = b; and the expression \c b has the evaluate-before-assigning \link flags flag\endlink. The most important example of such an expression is the \link GeneralProduct matrix product expression\endlink. For example, when you do - -\code matrix = matrix * matrix; \endcode - -Eigen first evaluates matrix * matrix into a temporary matrix, and then copies it into the original \c matrix. This guarantees a correct result as we saw above that lazy evaluation gives wrong results with matrix products. It also doesn't cost much, as the cost of the matrix product itself is much higher. - -What if you know that the result does no alias the operand of the product and want to force lazy evaluation? Then use \link MatrixBase::noalias() .noalias()\endlink instead. Here is an example: - -\code matrix1.noalias() = matrix2 * matrix2; \endcode - -Here, since we know that matrix2 is not the same matrix as matrix1, we know that lazy evaluation is not dangerous, so we may force lazy evaluation. Concretely, the effect of noalias() here is to bypass the evaluate-before-assigning \link flags flag\endlink. - -The second circumstance in which Eigen chooses immediate evaluation, is when it sees a nested expression such as a + b where \c b is already an expression having the evaluate-before-nesting \link flags flag\endlink. Again, the most important example of such an expression is the \link GeneralProduct matrix product expression\endlink. For example, when you do - -\code matrix1 = matrix2 + matrix3 * matrix4; \endcode - -the product matrix3 * matrix4 gets evaluated immediately into a temporary matrix. Indeed, experiments showed that it is often beneficial for performance to evaluate immediately matrix products when they are nested into bigger expressions. - -The third circumstance in which Eigen chooses immediate evaluation, is when its cost model shows that the total cost of an operation is reduced if a sub-expression gets evaluated into a temporary. Indeed, in certain cases, an intermediate result is sufficiently costly to compute and is reused sufficiently many times, that is worth "caching". Here is an example: - -\code matrix1 = matrix2 * (matrix3 + matrix4); \endcode - -Here, provided the matrices have at least 2 rows and 2 columns, each coefficienct of the expression matrix3 + matrix4 is going to be used several times in the matrix product. Instead of computing the sum everytime, it is much better to compute it once and store it in a temporary variable. Eigen understands this and evaluates matrix3 + matrix4 into a temporary variable before evaluating the product. - -*/ - -} diff --git a/testbed/nanogui/ext/eigen/doc/TopicLinearAlgebraDecompositions.dox b/testbed/nanogui/ext/eigen/doc/TopicLinearAlgebraDecompositions.dox deleted file mode 100644 index 8649cc27..00000000 --- a/testbed/nanogui/ext/eigen/doc/TopicLinearAlgebraDecompositions.dox +++ /dev/null @@ -1,261 +0,0 @@ -namespace Eigen { - -/** \eigenManualPage TopicLinearAlgebraDecompositions Catalogue of dense decompositions - -This page presents a catalogue of the dense matrix decompositions offered by Eigen. -For an introduction on linear solvers and decompositions, check this \link TutorialLinearAlgebra page \endlink. - -\section TopicLinAlgBigTable Catalogue of decompositions offered by Eigen - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

- -\b Notes: -
    -
  • \b 1: There exist two variants of the LDLT algorithm. Eigen's one produces a pure diagonal D matrix, and therefore it cannot handle indefinite matrices, unlike Lapack's one which produces a block diagonal D matrix.
    • -
  • \b 2: Eigenvalues, SVD and Schur decompositions rely on iterative algorithms. Their convergence speed depends on how well the eigenvalues are separated.
    • -
  • \b 3: Our JacobiSVD is two-sided, making for proven and optimal precision for square matrices. For non-square matrices, we have to use a QR preconditioner first. The default choice, ColPivHouseholderQR, is already very reliable, but if you want it to be proven, use FullPivHouseholderQR instead. -

Selfadjoint
-
For a real matrix, selfadjoint is a synonym for symmetric. For a complex matrix, selfadjoint is a synonym for \em hermitian. - More generally, a matrix \f$ A \f$ is selfadjoint if and only if it is equal to its adjoint \f$ A^* \f$. The adjoint is also called the \em conjugate \em transpose.
-
Positive/negative definite
-
A selfadjoint matrix \f$ A \f$ is positive definite if \f$ v^* A v > 0 \f$ for any non zero vector \f$ v \f$. - In the same vein, it is negative definite if \f$ v^* A v < 0 \f$ for any non zero vector \f$ v \f$
-
Positive/negative semidefinite
-
A selfadjoint matrix \f$ A \f$ is positive semi-definite if \f$ v^* A v \ge 0 \f$ for any non zero vector \f$ v \f$. - In the same vein, it is negative semi-definite if \f$ v^* A v \le 0 \f$ for any non zero vector \f$ v \f$
- -
Blocking
-
Means the algorithm can work per block, whence guaranteeing a good scaling of the performance for large matrices.
-
Implicit Multi Threading (MT)
-
Means the algorithm can take advantage of multicore processors via OpenMP. "Implicit" means the algortihm itself is not parallelized, but that it relies on parallelized matrix-matrix product rountines.
-
Explicit Multi Threading (MT)
-
Means the algorithm is explicitely parallelized to take advantage of multicore processors via OpenMP.
-
Meta-unroller
-
Means the algorithm is automatically and explicitly unrolled for very small fixed size matrices.

For small sizes, -especially for sizes smaller than (roughly) 16, using fixed sizes is hugely beneficial -to performance, as it allows Eigen to avoid dynamic memory allocation and to unroll -loops. Internally, a fixed-size Eigen matrix is just a plain array, i.e. doing -\code Matrix4f mymatrix; \endcode -really amounts to just doing -\code float mymatrix[16]; \endcode -so this really has zero runtime cost. By contrast, the array of a dynamic-size matrix -is always allocated on the heap, so doing -\code MatrixXf mymatrix(rows,columns); \endcode -amounts to doing -\code float *mymatrix = new float[rows*columns]; \endcode -and in addition to that, the MatrixXf object stores its number of rows and columns as -member variables. - -The limitation of using fixed sizes, of course, is that this is only possible -when you know the sizes at compile time. Also, for large enough sizes, say for sizes -greater than (roughly) 32, the performance benefit of using fixed sizes becomes negligible. -Worse, trying to create a very large matrix using fixed sizes inside a function could result in a -stack overflow, since Eigen will try to allocate the array automatically as a local variable, and -this is normally done on the stack. -Finally, depending on circumstances, Eigen can also be more aggressive trying to vectorize -(use SIMD instructions) when dynamic sizes are used, see \ref TopicVectorization "Vectorization". - -\section TutorialMatrixOptTemplParams Optional template parameters - -We mentioned at the beginning of this page that the Matrix class takes six template parameters, -but so far we only discussed the first three. The remaining three parameters are optional. Here is -the complete list of template parameters: -\code -Matrix -\endcode -\li \c Options is a bit field. Here, we discuss only one bit: \c RowMajor.

- -A SparseVector is a special case of a SparseMatrix where only the \c Values and \c InnerIndices arrays are stored. -There is no notion of compressed/uncompressed mode for a SparseVector. - - -\section TutorialSparseExample First example - -Before describing each individual class, let's start with the following typical example: solving the Laplace equation \f$ \nabla u = 0 \f$ on a regular 2D grid using a finite difference scheme and Dirichlet boundary conditions. -Such problem can be mathematically expressed as a linear problem of the form \f$ Ax=b \f$ where \f$ x \f$ is the vector of \c m unknowns (in our case, the values of the pixels), \f$ b \f$ is the right hand side vector resulting from the boundary conditions, and \f$ A \f$ is an \f$ m \times m \f$ matrix containing only a few non-zero elements resulting from the discretization of the Laplacian operator. - - - -

- -In this example, we start by defining a column-major sparse matrix type of double \c SparseMatrix, and a triplet list of the same scalar type \c Triplet. A triplet is a simple object representing a non-zero entry as the triplet: \c row index, \c column index, \c value. - -In the main function, we declare a list \c coefficients of triplets (as a std vector) and the right hand side vector \f$ b \f$ which are filled by the \a buildProblem function. -The raw and flat list of non-zero entries is then converted to a true SparseMatrix object \c A. -Note that the elements of the list do not have to be sorted, and possible duplicate entries will be summed up. - -The last step consists of effectively solving the assembled problem. -Since the resulting matrix \c A is symmetric by construction, we can perform a direct Cholesky factorization via the SimplicialLDLT class which behaves like its LDLT counterpart for dense objects. - -The resulting vector \c x contains the pixel values as a 1D array which is saved to a jpeg file shown on the right of the code above. - -Describing the \a buildProblem and \a save functions is out of the scope of this tutorial. They are given \ref TutorialSparse_example_details "here" for the curious and reproducibility purpose. - - - - -\section TutorialSparseSparseMatrix The SparseMatrix class - -\b %Matrix \b and \b vector \b properties \n - -The SparseMatrix and SparseVector classes take three template arguments: - * the scalar type (e.g., double) - * the storage order (ColMajor or RowMajor, the default is ColMajor) - * the inner index type (default is \c int). - -As for dense Matrix objects, constructors takes the size of the object. -Here are some examples: - -\code -SparseMatrix > mat(1000,2000); // declares a 1000x2000 column-major compressed sparse matrix of complex -SparseMatrix mat(1000,2000); // declares a 1000x2000 row-major compressed sparse matrix of double -SparseVector > vec(1000); // declares a column sparse vector of complex of size 1000 -SparseVector vec(1000); // declares a row sparse vector of double of size 1000 -\endcode - -In the rest of the tutorial, \c mat and \c vec represent any sparse-matrix and sparse-vector objects, respectively. - -The dimensions of a matrix can be queried using the following functions: - - - - - - - - - -
Standard \n dimensions\code -mat.rows() -mat.cols()\endcode\code -vec.size() \endcode
Sizes along the \n inner/outer dimensions\code -mat.innerSize() -mat.outerSize()\endcode
Number of non \n zero coefficients\code -mat.nonZeros() \endcode\code -vec.nonZeros() \endcode
- - -\b Iterating \b over \b the \b nonzero \b coefficients \n - -Random access to the elements of a sparse object can be done through the \c coeffRef(i,j) function. -However, this function involves a quite expensive binary search. -In most cases, one only wants to iterate over the non-zeros elements. This is achieved by a standard loop over the outer dimension, and then by iterating over the non-zeros of the current inner vector via an InnerIterator. Thus, the non-zero entries have to be visited in the same order than the storage order. -Here is an example: - - -
-\code -SparseMatrix mat(rows,cols); -for (int k=0; k::InnerIterator it(mat,k); it; ++it) - { - it.value(); - it.row(); // row index - it.col(); // col index (here it is equal to k) - it.index(); // inner index, here it is equal to it.row() - } -\endcode - -\code -SparseVector vec(size); -for (SparseVector::InnerIterator it(vec); it; ++it) -{ - it.value(); // == vec[ it.index() ] - it.index(); -} -\endcode -
-For a writable expression, the referenced value can be modified using the valueRef() function. -If the type of the sparse matrix or vector depends on a template parameter, then the \c typename keyword is -required to indicate that \c InnerIterator denotes a type; see \ref TopicTemplateKeyword for details. - - -\section TutorialSparseFilling Filling a sparse matrix - -Because of the special storage scheme of a SparseMatrix, special care has to be taken when adding new nonzero entries. -For instance, the cost of a single purely random insertion into a SparseMatrix is \c O(nnz), where \c nnz is the current number of non-zero coefficients. - -The simplest way to create a sparse matrix while guaranteeing good performance is thus to first build a list of so-called \em triplets, and then convert it to a SparseMatrix. - -Here is a typical usage example: -\code -typedef Eigen::Triplet T; -std::vector tripletList; -tripletList.reserve(estimation_of_entries); -for(...) -{ - // ... - tripletList.push_back(T(i,j,v_ij)); -} -SparseMatrixType mat(rows,cols); -mat.setFromTriplets(tripletList.begin(), tripletList.end()); -// mat is ready to go! -\endcode -The \c std::vector of triplets might contain the elements in arbitrary order, and might even contain duplicated elements that will be summed up by setFromTriplets(). -See the SparseMatrix::setFromTriplets() function and class Triplet for more details. - - -In some cases, however, slightly higher performance, and lower memory consumption can be reached by directly inserting the non-zeros into the destination matrix. -A typical scenario of this approach is illustrated bellow: -\code -1: SparseMatrix mat(rows,cols); // default is column major -2: mat.reserve(VectorXi::Constant(cols,6)); -3: for each i,j such that v_ij != 0 -4: mat.insert(i,j) = v_ij; // alternative: mat.coeffRef(i,j) += v_ij; -5: mat.makeCompressed(); // optional -\endcode - -- The key ingredient here is the line 2 where we reserve room for 6 non-zeros per column. In many cases, the number of non-zeros per column or row can easily be known in advance. If it varies significantly for each inner vector, then it is possible to specify a reserve size for each inner vector by providing a vector object with an operator[](int j) returning the reserve size of the \c j-th inner vector (e.g., via a VectorXi or std::vector). If only a rought estimate of the number of nonzeros per inner-vector can be obtained, it is highly recommended to overestimate it rather than the opposite. If this line is omitted, then the first insertion of a new element will reserve room for 2 elements per inner vector. -- The line 4 performs a sorted insertion. In this example, the ideal case is when the \c j-th column is not full and contains non-zeros whose inner-indices are smaller than \c i. In this case, this operation boils down to trivial O(1) operation. -- When calling insert(i,j) the element \c i \c ,j must not already exists, otherwise use the coeffRef(i,j) method that will allow to, e.g., accumulate values. This method first performs a binary search and finally calls insert(i,j) if the element does not already exist. It is more flexible than insert() but also more costly. -- The line 5 suppresses the remaining empty space and transforms the matrix into a compressed column storage. - - - -\section TutorialSparseFeatureSet Supported operators and functions - -Because of their special storage format, sparse matrices cannot offer the same level of flexibility than dense matrices. -In Eigen's sparse module we chose to expose only the subset of the dense matrix API which can be efficiently implemented. -In the following \em sm denotes a sparse matrix, \em sv a sparse vector, \em dm a dense matrix, and \em dv a dense vector. - -\subsection TutorialSparse_BasicOps Basic operations - -%Sparse expressions support most of the unary and binary coefficient wise operations: -\code -sm1.real() sm1.imag() -sm1 0.5*sm1 -sm1+sm2 sm1-sm2 sm1.cwiseProduct(sm2) -\endcode -However, a strong restriction is that the storage orders must match. For instance, in the following example: -\code -sm4 = sm1 + sm2 + sm3; -\endcode -sm1, sm2, and sm3 must all be row-major or all column major. -On the other hand, there is no restriction on the target matrix sm4. -For instance, this means that for computing \f$ A^T + A \f$, the matrix \f$ A^T \f$ must be evaluated into a temporary matrix of compatible storage order: -\code -SparseMatrix A, B; -B = SparseMatrix(A.transpose()) + A; -\endcode - -Some binary coefficient-wise operators can also mix sparse and dense expressions: -\code -sm2 = sm1.cwiseProduct(dm1); -dm1 += sm1; -\endcode - -However, it is not yet possible to add a sparse and a dense matrix as in dm2 = sm1 + dm1. -Please write this as the equivalent dm2 = dm1; dm2 += sm1 (we plan to lift this restriction -in the next release of %Eigen). - -%Sparse expressions also support transposition: -\code -sm1 = sm2.transpose(); -sm1 = sm2.adjoint(); -\endcode -However, there is no transposeInPlace() method. - - -\subsection TutorialSparse_Products Matrix products - -%Eigen supports various kind of sparse matrix products which are summarize below: - - \b sparse-dense: - \code -dv2 = sm1 * dv1; -dm2 = dm1 * sm1.adjoint(); -dm2 = 2. * sm1 * dm1; - \endcode - - \b symmetric \b sparse-dense. The product of a sparse symmetric matrix with a dense matrix (or vector) can also be optimized by specifying the symmetry with selfadjointView(): - \code -dm2 = sm1.selfadjointView<>() * dm1; // if all coefficients of A are stored -dm2 = A.selfadjointView() * dm1; // if only the upper part of A is stored -dm2 = A.selfadjointView() * dm1; // if only the lower part of A is stored - \endcode - - \b sparse-sparse. For sparse-sparse products, two different algorithms are available. The default one is conservative and preserve the explicit zeros that might appear: - \code -sm3 = sm1 * sm2; -sm3 = 4 * sm1.adjoint() * sm2; - \endcode - The second algorithm prunes on the fly the explicit zeros, or the values smaller than a given threshold. It is enabled and controlled through the prune() functions: - \code -sm3 = (sm1 * sm2).pruned(); // removes numerical zeros -sm3 = (sm1 * sm2).pruned(ref); // removes elements much smaller than ref -sm3 = (sm1 * sm2).pruned(ref,epsilon); // removes elements smaller than ref*epsilon - \endcode - - - \b permutations. Finally, permutations can be applied to sparse matrices too: - \code -PermutationMatrix P = ...; -sm2 = P * sm1; -sm2 = sm1 * P.inverse(); -sm2 = sm1.transpose() * P; - \endcode - - -\subsection TutorialSparse_TriangularSelfadjoint Triangular and selfadjoint views - -Just as with dense matrices, the triangularView() function can be used to address a triangular part of the matrix, and perform triangular solves with a dense right hand side: -\code -dm2 = sm1.triangularView(dm1); -dv2 = sm1.transpose().triangularView(dv1); -\endcode - -The selfadjointView() function permits various operations: - - optimized sparse-dense matrix products: - \code -dm2 = sm1.selfadjointView<>() * dm1; // if all coefficients of A are stored -dm2 = A.selfadjointView() * dm1; // if only the upper part of A is stored -dm2 = A.selfadjointView() * dm1; // if only the lower part of A is stored - \endcode - - copy of triangular parts: - \code -sm2 = sm1.selfadjointView(); // makes a full selfadjoint matrix from the upper triangular part -sm2.selfadjointView() = sm1.selfadjointView(); // copies the upper triangular part to the lower triangular part - \endcode - - application of symmetric permutations: - \code -PermutationMatrix P = ...; -sm2 = A.selfadjointView().twistedBy(P); // compute P S P' from the upper triangular part of A, and make it a full matrix -sm2.selfadjointView() = A.selfadjointView().twistedBy(P); // compute P S P' from the lower triangular part of A, and then only compute the lower part - \endcode - -Please, refer to the \link SparseQuickRefPage Quick Reference \endlink guide for the list of supported operations.

The extension above was created by the ARB, but there -are many different affixes, like `NV` for Nvidia and `AMD` for, well, AMD. Any -group may also use the generic `EXT` affix. Lists of extensions, together with -their specifications, can be found at the -[OpenGL Registry](http://www.opengl.org/registry/) and -[OpenGL ES Registry](https://www.khronos.org/registry/gles/). - - -@subsection context_glext_auto Loading extension with a loader library - -An extension loader library is the easiest and best way to access both OpenGL and -OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs. -They will take care of all the details of declaring and loading everything you -need. One such library is [glad](https://github.com/Dav1dde/glad) and there are -several others. - -The following example will use glad but all extension loader libraries work -similarly. - -First you need to generate the source files using the glad Python script. This -example generates a loader for any version of OpenGL, which is the default for -both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific -API versions and extension sets can be generated. The generated files are -written to the `output` directory. - -@code{.sh} -python main.py --generator c --no-loader --out-path output -@endcode - -The `--no-loader` option is added because GLFW already provides a function for -loading OpenGL and OpenGL ES function pointers and glad can call this instead of -having to implement its own. There are several other command-line options as -well. See the glad documentation for details. - -Add the generated `output/src/glad.c`, `output/include/glad/glad.h` and -`output/include/KHR/khrplatform.h` files to your build. Then you need to -include the glad header file, which will replace the OpenGL header of your -development environment. By including the glad header before the GLFW header, -it suppresses the development environment's OpenGL or OpenGL ES header. - -@code -#include -#include -@endcode - -Finally you need to initialize glad once you have a suitable current context. - -@code -window = glfwCreateWindow(640, 480, "My Window", NULL, NULL); -if (!window) -{ - ... -} - -glfwMakeContextCurrent(window); - -gladLoadGLLoader((GLADloadproc) glfwGetProcAddress); -@endcode - -Once glad has been loaded, you have access to all OpenGL core and extension -functions supported by both the context you created and the glad loader you -generated and you are ready to start rendering. - -You can specify a minimum required OpenGL or OpenGL ES version with -[context hints](@ref window_hints_ctx). If your needs are more complex, you can -check the actual OpenGL or OpenGL ES version with -[context attributes](@ref window_attribs_ctx), or you can check whether -a specific version is supported by the current context with the -`GLAD_GL_VERSION_x_x` booleans. - -@code -if (GLAD_GL_VERSION_3_2) -{ - // Call OpenGL 3.2+ specific code -} -@endcode - -To check whether a specific extension is supported, use the `GLAD_GL_xxx` -booleans. - -@code -if (GLAD_GL_ARB_debug_output) -{ - // Use GL_ARB_debug_output -} -@endcode - - -@subsection context_glext_manual Loading extensions manually - -__Do not use this technique__ unless it is absolutely necessary. An -[extension loader library](@ref context_glext_auto) will save you a ton of -tedious, repetitive, error prone work. - -To use a certain extension, you must first check whether the context supports -that extension and then, if it introduces new functions, retrieve the pointers -to those functions. GLFW provides @ref glfwExtensionSupported and @ref -glfwGetProcAddress for manual loading of extensions and new API functions. - -This section will demonstrate manual loading of OpenGL extensions. The loading -of OpenGL ES extensions is identical except for the name of the extension header. - - -@subsubsection context_glext_header The glext.h header - -The `glext.h` extension header is a continually updated file that defines the -interfaces for all OpenGL extensions. The latest version of this can always be -found at the [OpenGL Registry](http://www.opengl.org/registry/). There are also -extension headers for the various versions of OpenGL ES at the -[OpenGL ES Registry](https://www.khronos.org/registry/gles/). It it strongly -recommended that you use your own copy of the extension header, as the one -included in your development environment may be several years out of date and -may not include the extensions you wish to use. - -The header defines function pointer types for all functions of all extensions it -supports. These have names like `PFNGLGETDEBUGMESSAGELOGARBPROC` (for -`glGetDebugMessageLogARB`), i.e. the name is made uppercase and `PFN` (pointer -to function) and `PROC` (procedure) are added to the ends. - -To include the extension header, define [GLFW_INCLUDE_GLEXT](@ref build_macros) -before including the GLFW header. - -@code -#define GLFW_INCLUDE_GLEXT -#include -@endcode - - -@subsubsection context_glext_string Checking for extensions - -A given machine may not actually support the extension (it may have older -drivers or a graphics card that lacks the necessary hardware features), so it -is necessary to check at run-time whether the context supports the extension. -This is done with @ref glfwExtensionSupported. - -@code -if (glfwExtensionSupported("GL_ARB_debug_output")) -{ - // The extension is supported by the current context -} -@endcode - -The argument is a null terminated ASCII string with the extension name. If the -extension is supported, @ref glfwExtensionSupported returns `GL_TRUE`, otherwise -it returns `GL_FALSE`. - - -@subsubsection context_glext_proc Fetching function pointers - -Many extensions, though not all, require the use of new OpenGL functions. -These functions often do not have entry points in the client API libraries of -your operating system, making it necessary to fetch them at run time. You can -retrieve pointers to these functions with @ref glfwGetProcAddress. - -@code -PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog = glfwGetProcAddress("glGetDebugMessageLogARB"); -@endcode - -In general, you should avoid giving the function pointer variables the (exact) -same name as the function, as this may confuse your linker. Instead, you can -use a different prefix, like above, or some other naming scheme. - -Now that all the pieces have been introduced, here is what they might look like -when used together. - -@code -#define GLFW_INCLUDE_GLEXT -#include - -#define glGetDebugMessageLogARB pfnGetDebugMessageLog -PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog; - -// Flag indicating whether the extension is supported -int has_ARB_debug_output = 0; - -void load_extensions(void) -{ - if (glfwExtensionSupported("GL_ARB_debug_output")) - { - pfnGetDebugMessageLog = (PFNGLGETDEBUGMESSAGELOGARBPROC) glfwGetProcAddress("glGetDebugMessageLogARB"); - if (pfnGetDebugMessageLog) - { - // Both the extension name and the function pointer are present - has_ARB_debug_output = 1; - } - } -} - -void some_function(void) -{ - if (has_ARB_debug_output) - { - // Now the extension function can be called as usual - glGetDebugMessageLogARB(...); - } -} -@endcode - -*/ diff --git

While some can only be polled, like time, or -only received via callbacks, like scrolling, there are those that provide both -callbacks and polling. Where a callback is provided, that is the recommended -way to receive that kind of input. The more you can use callbacks the less time -your users' machines will need to spend polling. - -All input callbacks receive a window handle. By using the -[window user pointer](@ref window_userptr), you can access non-global structures -or objects from your callbacks. - -To get a better feel for how the various events callbacks behave, run the -`events` test program. It register every callback supported by GLFW and prints -out all arguments provided for every event, along with time and sequence -information. - - -@section events Event processing - -GLFW needs to communicate regularly with the window system both in order to -receive events and to show that the application hasn't locked up. Event -processing must be done regularly while you have visible windows and is normally -done each frame after [buffer swapping](@ref buffer_swap). - -There are two functions for processing pending events. @ref glfwPollEvents, -processes only those events that have already been received and then returns -immediately. - -@code -glfwPollEvents(); -@endcode - -This is the best choice when rendering continually, like most games do. - -If you only need to update the contents of the window when you receive new -input, @ref glfwWaitEvents is a better choice. - -@code -glfwWaitEvents(); -@endcode - -It puts the thread to sleep until at least one event has been received and then -processes all received events. This saves a great deal of CPU cycles and is -useful for, for example, editing tools. There must be at least one GLFW window -for this function to sleep. - -If the main thread is sleeping in @ref glfwWaitEvents, you can wake it from -another thread by posting an empty event to the event queue with @ref -glfwPostEmptyEvent. - -@code -glfwPostEmptyEvent(); -@endcode - -Do not assume that callbacks will _only_ be called through either of the above -functions. While it is necessary to process events in the event queue, some -window systems will send some events directly to the application, which in turn -causes callbacks to be called outside of regular event processing. - - -@section input_keyboard Keyboard input - -GLFW divides keyboard input into two categories; key events and character -events. Key events relate to actual physical keyboard keys, whereas character -events relate to the Unicode code points generated by pressing some of them. - -Keys and characters do not map 1:1. A single key press may produce several -characters, and a single character may require several keys to produce. This -may not be the case on your machine, but your users are likely not all using the -same keyboard layout, input method or even operating system as you. - - -@subsection input_key Key input - -If you wish to be notified when a physical key is pressed or released or when it -repeats, set a key callback. - -@code -glfwSetKeyCallback(window, key_callback); -@endcode - -The callback function receives the [keyboard key](@ref keys), platform-specific -scancode, key action and [modifier bits](@ref mods). - -@code -void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) -{ - if (key == GLFW_KEY_E && action == GLFW_PRESS) - activate_airship(); -} -@endcode - -The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`. The key -will be `GLFW_KEY_UNKNOWN` if GLFW lacks a key token for it. These keys still -have unique, if platform-specific scancodes. - -The scancode is unique for every key but is platform-specific, so a scancode -will map to different keys on different platforms. - -The key will be `GLFW_KEY_UNKNOWN` for special keys like _E-mail_ or _Play_ that -don't have a key token. Those keys will still have unique, if platform-specific -scancodes. - -Key states for [named keys](@ref keys) are also saved in per-window state arrays -that can be polled with @ref glfwGetKey. - -@code -int state = glfwGetKey(window, GLFW_KEY_E); -if (state == GLFW_PRESS) - activate_airship(); -@endcode - -The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. - -This function only returns cached key event state. It does not poll the -system for the current state of the key. - -Whenever you poll state, you risk missing the state change you are looking for. -If a pressed key is released again before you poll its state, you will have -missed the key press. The recommended solution for this is to use a -key callback, but there is also the `GLFW_STICKY_KEYS` input mode. - -@code -glfwSetInputMode(window, GLFW_STICKY_KEYS, 1); -@endcode - -When sticky keys mode is enabled, the pollable state of a key will remain -`GLFW_PRESS` until the state of that key is polled with @ref glfwGetKey. Once -it has been polled, if a key release event had been processed in the meantime, -the state will reset to `GLFW_RELEASE`, otherwise it will remain `GLFW_PRESS`. - -The `GLFW_KEY_LAST` constant holds the highest value of any -[named key](@ref keys). - - -@subsection input_char Text input - -GLFW supports text input in the form of a stream of -[Unicode code points](https://en.wikipedia.org/wiki/Unicode), as produced by the -operating system text input system. Unlike key input, text input obeys keyboard -layouts and modifier keys and supports composing characters using -[dead keys](https://en.wikipedia.org/wiki/Dead_key).

By default, the cursor mode is `GLFW_CURSOR_NORMAL`, -meaning the regular arrow cursor (or another cursor set with @ref glfwSetCursor) -is used and cursor motion is not limited. - -If you wish to implement mouse motion based camera controls or other input -schemes that require unlimited mouse movement, set the cursor mode to -`GLFW_CURSOR_DISABLED`. - -@code -glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED); -@endcode - -This will hide the cursor and lock it to the specified window. GLFW will then -take care of all the details of cursor re-centering and offset calculation and -providing the application with a virtual cursor position. This virtual position -is provided normally via both the cursor position callback and through polling. - -@note You should not implement your own version of this functionality using -other features of GLFW. It is not supported and will not work as robustly as -`GLFW_CURSOR_DISABLED`. - -If you just wish the cursor to become hidden when it is over a window, set -the cursor mode to `GLFW_CURSOR_HIDDEN`. - -@code -glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_HIDDEN); -@endcode - -This mode puts no limit on the motion of the cursor. - -To exit out of either of these special modes, restore the `GLFW_CURSOR_NORMAL` -cursor mode. - -@code -glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_NORMAL); -@endcode - - -@subsection cursor_object Cursor objects - -GLFW supports creating both custom and system theme cursor images, encapsulated -as @ref GLFWcursor objects.

The pixels are -arranged canonically as sequential rows, starting from the top-left corner. - - -@subsubsection cursor_standard Standard cursor creation - -A cursor with a [standard shape](@ref shapes) from the current system cursor -theme can be can be created with @ref glfwCreateStandardCursor. - -@code -GLFWcursor* cursor = glfwCreateStandardCursor(GLFW_HRESIZE_CURSOR); -@endcode - -These cursor objects behave in the exact same way as those created with @ref -glfwCreateCursor except that the system cursor theme provides the actual image. - - -@subsubsection cursor_destruction Cursor destruction - -When a cursor is no longer needed, destroy it with @ref glfwDestroyCursor. - -@code -glfwDestroyCursor(cursor); -@endcode - -Cursor destruction always succeeds. All cursors remaining when @ref -glfwTerminate is called are destroyed as well. - - -@subsubsection cursor_set Cursor setting - -A cursor can be set as current for a window with @ref glfwSetCursor. - -@code -glfwSetCursor(window, cursor); -@endcode - -Once set, the cursor image will be used as long as the system cursor is over the -client area of the window and the [cursor mode](@ref cursor_mode) is set -to `GLFW_CURSOR_NORMAL`. - -A single cursor may be set for any number of windows. - -To remove a cursor from a window, set the cursor of that window to `NULL`. - -@code -glfwSetCursor(window, NULL); -@endcode - -When a cursor is destroyed, it is removed from any window where it is set. This -does not affect the cursor modes of those windows. - - -@subsection cursor_enter Cursor enter/leave events - -If you wish to be notified when the cursor enters or leaves the client area of -a window, set a cursor enter/leave callback. - -@code -glfwSetCursorEnterCallback(window, cursor_enter_callback); -@endcode - -The callback function receives the new classification of the cursor. - -@code -void cursor_enter_callback(GLFWwindow* window, int entered) -{ - if (entered) - { - // The cursor entered the client area of the window - } - else - { - // The cursor left the client area of the window - } -} -@endcode - - -@subsection input_mouse_button Mouse button input - -If you wish to be notified when a mouse button is pressed or released, set -a mouse button callback. - -@code -glfwSetMouseButtonCallback(window, mouse_button_callback); -@endcode - -The callback function receives the [mouse button](@ref buttons), button action -and [modifier bits](@ref mods). - -@code -void mouse_button_callback(GLFWwindow* window, int button, int action, int mods) -{ - if (button == GLFW_MOUSE_BUTTON_RIGHT && action == GLFW_PRESS) - popup_menu(); -} -@endcode - -The action is one of `GLFW_PRESS` or `GLFW_RELEASE`. - -Mouse button states for [named buttons](@ref buttons) are also saved in -per-window state arrays that can be polled with @ref glfwGetMouseButton. - -@code -int state = glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT); -if (state == GLFW_PRESS) - upgrade_cow(); -@endcode - -The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. - -This function only returns cached mouse button event state. It does not poll -the system for the current state of the mouse button. - -Whenever you poll state, you risk missing the state change you are looking for. -If a pressed mouse button is released again before you poll its state, you will have -missed the button press. The recommended solution for this is to use a -mouse button callback, but there is also the `GLFW_STICKY_MOUSE_BUTTONS` -input mode. - -@code -glfwSetInputMode(window, GLFW_STICKY_MOUSE_BUTTONS, 1); -@endcode - -When sticky mouse buttons mode is enabled, the pollable state of a mouse button -will remain `GLFW_PRESS` until the state of that button is polled with @ref -glfwGetMouseButton. Once it has been polled, if a mouse button release event -had been processed in the meantime, the state will reset to `GLFW_RELEASE`, -otherwise it will remain `GLFW_PRESS`. - -The `GLFW_MOUSE_BUTTON_LAST` constant holds the highest value of any -[named button](@ref buttons). - - -@subsection scrolling Scroll input - -If you wish to be notified when the user scrolls, whether with a mouse wheel or -touchpad gesture, set a scroll callback. - -@code -glfwSetScrollCallback(window, scroll_callback); -@endcode - -The callback function receives two-dimensional scroll offsets. - -@code -void scroll_callback(GLFWwindow* window, double xoffset, double yoffset) -{ -} -@endcode - -A simple mouse wheel, being vertical, provides offsets along the Y-axis. - - -@section joystick Joystick input - -The joystick functions expose connected joysticks and controllers, with both -referred to as joysticks. It supports up to sixteen joysticks, ranging from -`GLFW_JOYSTICK_1`, `GLFW_JOYSTICK_2` up to `GLFW_JOYSTICK_LAST`. You can test -whether a [joystick](@ref joysticks) is present with @ref glfwJoystickPresent. - -@code -int present = glfwJoystickPresent(GLFW_JOYSTICK_1); -@endcode - -When GLFW is initialized, detected joysticks are added to to the beginning of -the array, starting with `GLFW_JOYSTICK_1`. Once a joystick is detected, it -keeps its assigned index until it is disconnected, so as joysticks are connected -and disconnected, they will become spread out. - -Joystick state is updated as needed when a joystick function is called and does -not require a window to be created or @ref glfwPollEvents or @ref glfwWaitEvents -to be called. - - -@subsection joystick_axis Joystick axis states - -The positions of all axes of a joystick are returned by @ref -glfwGetJoystickAxes.

However, no GLFW function may be called from any other -thread until GLFW has been successfully initialized on the main thread, -including functions that may called before initialization. - -The reference documentation for every GLFW function states whether it is limited -to the main thread. - -The following categories of functions are and will remain limited to the main -thread due to the limitations of one or several platforms: - - - Initialization and termination - - Event processing - - Creation and destruction of window, context and cursor objects - -Because event processing must be performed on the main thread, all callbacks -except for the error callback will only be called on that thread. The error -callback may be called on any thread, as any GLFW function may generate errors. - -The posting of empty events may be done from any thread.

Note that @ref glfwGetKey still returns only `GLFW_PRESS` or -`GLFW_RELEASE`. - - -@subsection moving_keys Physical key input - -GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to -the values generated by the current keyboard layout. The tokens are named -according to the values they would have using the standard US layout, but this -is only a convenience, as most programmers are assumed to know that layout. -This means that (for example) `GLFW_KEY_LEFT_BRACKET` is always a single key and -is the same key in the same place regardless of what keyboard layouts the users -of your program has. - -The key input facility was never meant for text input, although using it that -way worked slightly better in GLFW 2. If you were using it to input text, you -should be using the character callback instead, on both GLFW 2 and 3. This will -give you the characters being input, as opposed to the keys being pressed. - -GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of -having to remember whether to check for `'a'` or `'A'`, you now check for -`GLFW_KEY_A`. - - -@subsection moving_joystick Joystick function changes - -The `glfwGetJoystickPos` function has been renamed to @ref glfwGetJoystickAxes. - -The `glfwGetJoystickParam` function and the `GLFW_PRESENT`, `GLFW_AXES` and -`GLFW_BUTTONS` tokens have been replaced by the @ref glfwJoystickPresent -function as well as axis and button counts returned by the @ref -glfwGetJoystickAxes and @ref glfwGetJoystickButtons functions. - - -@subsection moving_mbcs Win32 MBCS support - -The Win32 port of GLFW 3 will not compile in -[MBCS mode](http://msdn.microsoft.com/en-us/library/5z097dxa.aspx). -However, because the use of the Unicode version of the Win32 API doesn't affect -the process as a whole, but only those windows created using it, it's perfectly -possible to call MBCS functions from other parts of the same application. -Therefore, even if an application using GLFW has MBCS mode code, there's no need -for GLFW itself to support it. - - -@subsection moving_windows Support for versions of Windows older than XP - -All explicit support for version of Windows older than XP has been removed. -There is no code that actively prevents GLFW 3 from running on these earlier -versions, but it uses Win32 functions that those versions lack. - -Windows XP was released in 2001, and by now (January 2015) it has not only -replaced almost all earlier versions of Windows, but is itself rapidly being -replaced by Windows 7 and 8. The MSDN library doesn't even provide -documentation for version older than Windows 2000, making it difficult to -maintain compatibility with these versions even if it was deemed worth the -effort. - -The Win32 API has also not stood still, and GLFW 3 uses many functions only -present on Windows XP or later.

That means that each window has -two rendering buffers; a front buffer and a back buffer.

Event -processing must be done regularly while you have visible windows and is normally -done each frame after buffer swapping. - -There are two methods for processing pending events; polling and waiting. This -example will use event polling, which processes only those events that have -already been received and then returns immediately. - -@code -glfwPollEvents(); -@endcode - -This is the best choice when rendering continually, like most games do. If -instead you only need to update your rendering once you have received new input, -@ref glfwWaitEvents is a better choice. It waits until at least one event has -been received, putting the thread to sleep in the meantime, and then processes -all received events.

Initial -input focus is controlled by the [window hint](@ref window_hints_wnd) with the -same name. - -`GLFW_ICONIFIED` indicates whether the specified window is iconified, whether by -the user or with @ref glfwIconifyWindow. - -`GLFW_VISIBLE` indicates whether the specified window is visible. Window -visibility can be controlled with @ref glfwShowWindow and @ref glfwHideWindow -and initial visibility is controlled by the [window hint](@ref window_hints_wnd) -with the same name. - -`GLFW_RESIZABLE` indicates whether the specified window is resizable _by the -user_. This is set on creation with the [window hint](@ref window_hints_wnd) - with the same name. - -`GLFW_DECORATED` indicates whether the specified window has decorations such as -a border, a close widget, etc. This is set on creation with the -[window hint](@ref window_hints_wnd) with the same name. - -`GLFW_FLOATING` indicates whether the specified window is floating, also called -topmost or always-on-top. This is controlled by the -[window hint](@ref window_hints_wnd) with the same name. - - -@subsubsection window_attribs_ctx Context related attributes - -`GLFW_CLIENT_API` indicates the client API provided by the window's context; -either `GLFW_OPENGL_API` or `GLFW_OPENGL_ES_API`. - -`GLFW_CONTEXT_VERSION_MAJOR`, `GLFW_CONTEXT_VERSION_MINOR` and -`GLFW_CONTEXT_REVISION` indicate the client API version of the window's context. - -`GLFW_OPENGL_FORWARD_COMPAT` is `GL_TRUE` if the window's context is an OpenGL -forward-compatible one, or `GL_FALSE` otherwise. - -`GLFW_OPENGL_DEBUG_CONTEXT` is `GL_TRUE` if the window's context is an OpenGL -debug context, or `GL_FALSE` otherwise. - -`GLFW_OPENGL_PROFILE` indicates the OpenGL profile used by the context. This is -`GLFW_OPENGL_CORE_PROFILE` or `GLFW_OPENGL_COMPAT_PROFILE` if the context uses -a known profile, or `GLFW_OPENGL_ANY_PROFILE` if the OpenGL profile is unknown -or the context is an OpenGL ES context. Note that the returned profile may not -match the profile bits of the context flags, as GLFW will try other means of -detecting the profile when no bits are set. - -`GLFW_CONTEXT_ROBUSTNESS` indicates the robustness strategy used by the context. -This is `GLFW_LOSE_CONTEXT_ON_RESET` or `GLFW_NO_RESET_NOTIFICATION` if the -window's context supports robustness, or `GLFW_NO_ROBUSTNESS` otherwise. - - -@section buffer_swap Buffer swapping - -GLFW windows are by default double buffered. That means that you have two -rendering buffers; a front buffer and a back buffer. The front buffer is -the one being displayed and the back buffer the one you render to. - -When the entire frame has been rendered, it is time to swap the back and the -front buffers in order to display what has been rendered and begin rendering -a new frame. This is done with @ref glfwSwapBuffers. - -@code -glfwSwapBuffers(window); -@endcode - -Sometimes it can be useful to select when the buffer swap will occur. With the -function @ref glfwSwapInterval it is possible to select the minimum number of -monitor refreshes the driver wait should from the time @ref glfwSwapBuffers was -called before swapping the buffers: - -@code -glfwSwapInterval(1); -@endcode - -If the interval is zero, the swap will take place immediately when @ref -glfwSwapBuffers is called without waiting for a refresh. Otherwise at least -interval retraces will pass between each buffer swap. Using a swap interval of -zero can be useful for benchmarking purposes, when it is not desirable to -measure the time it takes to wait for the vertical retrace. However, a swap -interval of one lets you avoid tearing. - -Note that this may not work on all machines, as some drivers have -user-controlled settings that override any swap interval the application -requests. It is also by default disabled on Windows Vista and later when using -DWM (Aero), as using it there sometimes leads to severe jitter. You can -forcibly enable it for machines using DWM using @ref compile_options_win32. - -*/ diff --git a/testbed/nanogui/ext/glfw/examples/CMakeLists.txt b/testbed/nanogui/ext/glfw/examples/CMakeLists.txt deleted file mode 100644 index 1232279d..00000000 --- a/testbed/nanogui/ext/glfw/examples/CMakeLists.txt +++ /dev/null @@ -1,82 +0,0 @@ - -link_libraries(glfw "${OPENGL_glu_LIBRARY}") - -if (BUILD_SHARED_LIBS) - add_definitions(-DGLFW_DLL) - link_libraries("${OPENGL_gl_LIBRARY}" "${MATH_LIBRARY}") -else() - link_libraries(${glfw_LIBRARIES}) -endif() - -include_directories("${GLFW_SOURCE_DIR}/include" - "${GLFW_SOURCE_DIR}/deps") - -if ("${OPENGL_INCLUDE_DIR}") - include_directories("${OPENGL_INCLUDE_DIR}") -endif() - -set(GLAD "${GLFW_SOURCE_DIR}/deps/glad/glad.h" - "${GLFW_SOURCE_DIR}/deps/glad.c") -set(GETOPT "${GLFW_SOURCE_DIR}/deps/getopt.h" - "${GLFW_SOURCE_DIR}/deps/getopt.c") -set(TINYCTHREAD "${GLFW_SOURCE_DIR}/deps/tinycthread.h" - "${GLFW_SOURCE_DIR}/deps/tinycthread.c") - -if (APPLE) - # Set fancy names for bundles - add_executable(Boing MACOSX_BUNDLE boing.c) - add_executable(Gears MACOSX_BUNDLE gears.c) - add_executable(Heightmap MACOSX_BUNDLE heightmap.c ${GLAD}) - add_executable(Particles MACOSX_BUNDLE particles.c ${TINYCTHREAD}) - add_executable(Simple MACOSX_BUNDLE simple.c) - add_executable(SplitView MACOSX_BUNDLE splitview.c) - add_executable(Wave MACOSX_BUNDLE wave.c) - - set_target_properties(Boing PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Boing") - set_target_properties(Gears PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Gears") - set_target_properties(Heightmap PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Heightmap") - set_target_properties(Particles PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Particles") - set_target_properties(Simple PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Simple") - set_target_properties(SplitView PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Split View") - set_target_properties(Wave PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Wave") - - set_target_properties(Boing Gears Heightmap Particles Simple SplitView Wave PROPERTIES - FOLDER "GLFW3/Examples" - MACOSX_BUNDLE_INFO_PLIST "${GLFW_SOURCE_DIR}/CMake/AppleInfo.plist") - -else() - # Set boring names for executables - add_executable(boing WIN32 boing.c) - add_executable(gears WIN32 gears.c) - add_executable(heightmap WIN32 heightmap.c ${GLAD}) - add_executable(particles WIN32 particles.c ${TINYCTHREAD} ${GETOPT}) - add_executable(simple WIN32 simple.c) - add_executable(splitview WIN32 splitview.c) - add_executable(wave WIN32 wave.c) - - set_target_properties(boing gears heightmap particles simple splitview wave PROPERTIES - FOLDER "GLFW3/Examples") -endif() - -if (APPLE) - target_link_libraries(Particles "${CMAKE_THREAD_LIBS_INIT}") -elseif (UNIX) - target_link_libraries(particles "${CMAKE_THREAD_LIBS_INIT}" "${RT_LIBRARY}") -endif() - -if (MSVC) - set(WINDOWS_BINARIES boing gears heightmap particles simple splitview wave) - - # Tell MSVC to use main instead of WinMain for Windows subsystem executables - set_target_properties(${WINDOWS_BINARIES} PROPERTIES - LINK_FLAGS "/ENTRY:mainCRTStartup") -endif() - -if (APPLE) - set(BUNDLE_BINARIES Boing Gears Heightmap Particles Simple SplitView Wave) - - set_target_properties(${BUNDLE_BINARIES} PROPERTIES - MACOSX_BUNDLE_SHORT_VERSION_STRING ${GLFW_VERSION} - MACOSX_BUNDLE_LONG_VERSION_STRING ${GLFW_VERSION_FULL}) -endif() - diff --git a/testbed/nanogui/ext/glfw/examples/boing.c b/testbed/nanogui/ext/glfw/examples/boing.c deleted file mode 100644 index ec313596..00000000 --- a/testbed/nanogui/ext/glfw/examples/boing.c +++ /dev/null @@ -1,669 +0,0 @@ -/***************************************************************************** - * Title: GLBoing - * Desc: Tribute to Amiga Boing. - * Author: Jim Brooks - * Original Amiga authors were R.J.
