f5e16847df added btMatrix3x3::getEulerYPR, which is consistent with updated setEulerYPR. 
removed unused getEuler.
Thanks to Georg Wuensch, see http://code.google.com/p/bullet/issues/detail?id=104

c5112e68e5 make sure the btDbvtBroadphase doesn't add/remove any pairs, use the btNullPairCache 2008-10-28 05:51:32 +00:00

1ff6420ffb Use the add support for double and float triangle vertices. If it has a bad impact on performance, we can hide it behind an #ifdef for double precision vertex support. 
Fix btConvexTriangleMeshShape::calculatePrincipalAxisTransform
Both thanks to Ole.

Use our own union to extract a scalar value from an SSE intrinsic (instead of relying on MSVC-only m128_u32
Thanks to BlindSide

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)

4cbb3f2e7b Added btGhostObject and btPairCachingGhostObject functionality. 
It is a fast way to keep track of overlapping objects in an area, and doing rayTest and convexSweepTest for overlapping objects, instead of btCollisionWorld::rayTest/convexSweepTest.

Updated KinematicCharacterController to use btPairCachingGhostObject.

b48d05d52a Preliminary adding btGhostObject. 
It can be useful for collision sensors, explosion objects, character controller etc.

Similar to Havok phantom object.

945b299e56 some rayTest improvements in btDbvt::rayTestInternal, it avoids/reduces memory allocations during stack allocation (by sharing a persistent m_stack) 
and rayTestInternal re-uses precomputed invRayDirection/signs.
also did some performance comparison with different ray-AABB test, from 
http://jgt.akpeters.com/papers/EisemannEtAl07/

In short: it is faster, but it is not clear how to cull ray segments using ray slopes: when rays starts inside the AABB, we get a negative t value, but negatives also get false t-values...

60ce828419 Autoformat selection for soft body, btDbvt related classes (no code change, just layout using Visual Studio) 2008-10-15 18:39:27 +00:00
erwin.coumans
cac172d422 Use consistent rayFrom/rayTo API for rayTest for btDbvt and btSoftBody, instead of rayCast/collideRAY(origin,direction). This means RayFromToCaster has a fraction [0..1] instead of distance [0..INF] 
Renamed collideRay -> rayTest to reflect change to (rayFrom,rayTo) interface.
Re-use btRayAabb2 function from src/LinearMath/btAabbUtil2.h in btDbvt instead of duplicated implementation.

e6c850f13b Fix/improve raycast performance for btBvhTriangleMeshShape (btQuantizedBvh, btOptimizedBvh) 
Add raycast acceleration for btAxisSweep3, using btDbvtBroadphase, providing large speedup. Can be disabled in constructor to safe memory.

fffca75e9f Make raycast benchmark default, to show improved raycasting performance. 
Add rayTest to btBroadphaseInterface, and implement efficient version for btDbvtBroadphase to accelerate raycasting.
btAxisSweep3, btSimpleBroadphase and btMultiSapBroadphase implement brute-force method (as before). For now, it is recommended to use btDbvtBroadphase for fastest world raycast.
