Detailed Description

This class manages a mesh supplied by the btStridingMeshInterface interface.

Set of btGImpactMeshShapePart parts

Simply create this shape by passing the btStridingMeshInterface to the constructor btGImpactMeshShape, then you must call updateBound() after creating the mesh
You can handle deformable meshes with this shape, by calling postUpdate() every time when changing the mesh vertices.
