erwin.coumans	4d0c11cd95	add PE_REF macro to allow Win32 SIMD for Physics Effects box-boxBoxDistance (although performance hardly differs)	2008-11-15 22:40:09 +00:00
erwin.coumans	bcd0f48c28	some doxygen updates, added some comments to classes, fix broken links, rename some prefix some internal GIMPACT collision structures using (for example use GIM_AABB instead of BT_AAABB), ... removed obsolete btGjkEpa (it was replaced by btGjkEpa2 ages ago)	2008-11-04 04:01:31 +00:00
erwin.coumans	e6202f58ad	1)Added SCE Physics Effects boxBoxDistance ... BulletMultiThreaded/NarrowPhaseCollision makes use of this boxBoxDistance. Cache some values in src/BulletMultiThreaded/SpuContactManifoldCollisionAlgorithm.cpp, to avoid DMA transfers 2) Added btConvexSeparatingDistanceUtil: this allows caching of separating distance/vector as early-out to avoid convex-convex collision detection. btConvexSeparatingDistanceUtil is used in src/BulletCollision/CollisionDispatch/btConvexConvexAlgorithm.cpp and can be controlled by btDispatcherInfo.m_useConvexConservativeDistanceUtil/m_convexConservativeDistanceThreshold 3) Use BulletMultiThreaded/vectormath/scalar/cpp/vectormath/scalar/cpp/vectormath_aos.h as fallback for non-PlayStation 3 Cell SPU/PPU platforms (used by boxBoxDistance). Note there are other implementations in Extras/vectormath folder, that are potentially faster for IBM Cell SDK 3.0 SPU (libspe2)	2008-10-20 20:12:39 +00:00
