com.bulletphysics.extras.gimpact.GImpactMeshShapePart

public class GImpactMeshShapePart
extends GImpactShapeInterface

This class manages a sub part of a mesh supplied by the StridingMeshInterface interface.

- Simply create this shape by passing the StridingMeshInterface to the constructor GImpactMeshShapePart, then you must call updateBound() after creating the mesh
- When making operations with this shape, you must call lock before accessing to the trimesh primitives, and then call unlock
- You can handle deformable meshes with this shape, by calling postUpdate() every time when changing the mesh vertices.
