92c69ddefa added missing files to build systems for CMake and Automake (Makefile.am still needs to add additional include directory for BulletMultiThreaded, for vectormath) 2008-10-21 19:06:29 +00:00

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.

675c45f42d 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

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.

0ff15db3f3 + capsule should subtract margin, and take local scaling into account.
+ boxshape uses btFsels
+ add assert in btGjkPairDetector that the new non-virtual method produces the same result as old non-virtual
