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)
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.
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.
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.
Thanks to sparkprime, see http://code.google.com/p/bullet/issues/detail?id=74
Fixed btCompoundShape/btCapsuleShape/btGImpactShape for missing m_shapeType, and added an assert in DemoApplication::localCreateRigidBody for invalid shape types.
Add dynamic aabb tree (btDbvt) optimization for btCompoundShape/btCompoundCollisionAlgorithm
Add btTransformAabb util, todo: deploy it throughout the codebase
Disable btSphereBoxCollisionAlgorithm, it is broken.
More fixes for btSimpleBroadphase
Moved quickstep to Extras/quickstep folder, so developers don't get confused which constraint solver is default.
btDbvtBroadphase:
- Fixed a performance issues reported by 'reltham'
- Added btDbvtBroadphase::optimize() for people who want good performances right away or don't do dynamics.
- fixed compilation issues when DBVT_BP_PROFILE was set.
btSoftBody:
- Fixed singular matrix issues related to polar decomposition (flat meshes).
DemoApplication:
- Shadows (enable/disable through 'g' or DemoApplication::setShadows(bool)).
- Texture can be enable/disable through 'u'
CDFramework:
- fixed compilation issues.
rename AddSingleResult to addSingleResult
moved collision filtering for btCollisionWorld::rayTest and btCollisionWorld::convexSweepTest from argument to the callback needsCollision
+ improved btSubsimplexConvexCast, btContinuousConvexCollision and btGjkConvexCast to support configuration that start in touching/penetration, required for 'sliding'.
+ added files to CMakeLists.txt for CharacterController
+ bump up version to 2.70 (preparation for beta)
