minor fix in btTransformUtil::calculateVelocityQuaternion, report zero angular velocity on identical transforms (using above operator to check identical transforms)
Disable libxml LIBXML_MODULE_EXTENSION
Fixed include path in btConeTwistConstraint (it should be relative to src folder, not using ../../ )
Thanks to ejtttje, http://code.google.com/p/bullet/issues/detail?id=129
Add CMake install support for libbulletmath,libbulletcollision,libbulletdynamics,libbulletsoftbody,and toplevel include files
Options to enable/disable BUILD_DEMOS and BUILD_ETRAS
Fixed compile issue in BulletMultiThreaded
Fixed double-precision issues with btMatrix3x3::getEulerZYX
btQuantizedBvh has a version number, memory layout might be different now (due to aligned btVector3)
reorganized some data members of some classes, to reduce memory footprint
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)
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...
1) re-allocate a pool allocator, if one of the soft body collision algorithms is larger than max pool element size
2) manage child shapes properly, and call RemoveReferences on the m_sparsesdf
Add dynamic aabb tree (btDbvt) optimization for btCompoundShape/btCompoundCollisionAlgorithm
Add btTransformAabb util, todo: deploy it throughout the codebase
+ 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)
call CProfileManager::CleanupMemory(), to cleanup btQuickprof memory.
changed include from #include <new.h> to #include <new> in btOdeQuickstepConstraintSolver.cpp
Thanks Martijn Reuvers from Two Tribes B.V. (www.twotribes.com) for the patch
To make this work more visible, suppress warnings in external libraries in Extras (COLLADA_DOM, libxml and glui contain many warnings)
Added PreprocessorDefinitions: _CRT_SECURE_NO_DEPRECATE;_CRT_NONSTDC_NO_DEPRECATE to vcproj files
moved Extras/ConvexHull/btConvexHull.* to src/LinearMath/btConvexHull.*
removed btCollisionObject::m_internalOwner, replaced it by m_internalType. This should not affect external API (it was clearly marked as internal)
Added very basic drawTriangle for btIDebugDraw, useful for basic softbody visualization.
Added btGjkEpa2, contribution by Nathanael Presson. Improved version of EPA penetration depth computation, more suitable for multi-core/SPU (less memory usage). Note: btGjkEpa2 is not enabled by default currently.
