Function Documentation

void btAdjustInternalEdgeContacts	(	btManifoldPoint &	cp,
		const btCollisionObject *	trimeshColObj0,
		const btCollisionObject *	otherColObj1,
		int	partId0,
		int	index0,
		int	normalAdjustFlags = 0
	)

Changes a btManifoldPoint collision normal to the normal from the mesh.

Call the btFixMeshNormal to adjust the collision normal, using the triangle info map (generated using btGenerateInternalEdgeInfo) If this info map is missing, or the triangle is not store in this map, nothing will be done
