784e7fdb39Added support for separating axis test for polyhedral shapes Added initial support for polyhedral contact clipping. This clipping takes a separating normal, that can be computed using either SAT or GJK/EPA. To enable clipping, use btPolyhedralConvexShape::initializePolyhedralFeatures(); (needs to be enabled for both convex shapes) No concave trimesh support for SAT/clipping yet. To enable SAT, see the toggle in btConvexConvexAlgorithm. Fixes in contact normal in btGjkPairDetector. Hopefully this doesn't cause any regression (we need unit tests!)

a522cb98d9Added a first version of FractureDemo, showing basic fracture and glue of rigid bodies. It assumes a btCompoundShaps (where the childshapes are the pre-fractured pieces) The btFractureBody is a class derived from btRigidBody, dealing with the collision impacts and connectivity/propagating the fracture. Press the F key to toggle between fracture and glue mode This is preliminary work, can be used as a starting point to implement your own fracture.
