     a rigid body. First, you can set it directly using the \texttt{RigidBody::setLocalInertiaTensor()} method. Note that this will set the inertia tensor
     of the body in local-space coordinates which is usually a diagonal matrix. This method takes a \texttt{Vector3} with the three diagonal entries of the
     matrix. Secondly, the local inertia tensor can be computed automatically using the mass density, shape and transform of all the colliders of the body.
