* This class is used to describe the vertices and faces of a triangular mesh.
|

|
|
* A TriangleVertexArray represents a continuous array of vertices and indexes
|
||
|
|
* of a triangular mesh. When you create a TriangleVertexArray, no data is copied
|
||
|
|
* into the array. It only stores pointer to the da. The purpose is to allow
|
||
|
|
* the user to share vertices data between the physics engine and the rendering
|
||
|
|
* part. Therefore, make sure that the data pointed by a TriangleVertexArray
|
||
|
|
* remain valid during the TriangleVertexArray life.
