Turned on by default, use m_useOffsetForConstraintFrame = false to use old setup
Use "O" (capital 'o') button to toggle it in SliderConstraintDemo and ConstraintDemo
Total applied impulse copied back from btSolverConstraint to btTypedConstraint
Minor fixes (#ifndef SPU_COLLISION_OBJECT_WRAPPER_H block etc)
Only update 'setNumTasks' when necessary
Revert vectormath.h include (can't resolve conflicts with PS3 SDK, need additional #include path)
Make btTypedConstraint and btPersistentManifold both derive from btTypedObject to make SPU-side generic constraint solver easier.
Note: all build systems need to be updated: remove SpuVoronoiSimplexSolver.cpp, SpuGjkPairDetector.cpp, SpuEpaPenetrationDepthSolver.cpp, SpuGjkEpa2.cpp
Also comment-out some code for __SPU__ to reduce code size
Added btContactConstraint (only used on PS3 SPU right now, better to use btPersistentManifold directly for contact constraints)
Improved readblend utility library (see also usage in http://gamekit.googlecode.com with Irrlicht)
Fix for btConvexConvexAlgorithm, potential division by zero
Thanks linzner http://code.google.com/p/bullet/issues/detail?id=260
+ Allow user to enable useConvexConservativeDistanceUtil . Use dynamicsWorld->getDispatchInfo().m_useConvexConservativeDistanceUtil = true;
(see Demos/Benchmarks/Benchmark4 (convex objects falling down)
+ Fix for plane drawing (just wire-frame)
+ Gimpact: use collision margin of 0.07 for demo (because BULLET_TRIANGLE_COLLISION is used)
+ replace dot,cross,distance,angle,triple in btVector3 by btDot, btCross,btDistance,btAngle,btDistance to avoid naming conflicts
+ Some fixes in GJK penetration depth normal direction (broken in a previous commit)
+ fix in calculateDiffAxisAngleQuaternion to make ConvexConservativeDistanceUtil work properly
+ allow debug drawing to debug btContinuousConvexCollision
+ add comment/warning that btTriangleMesh::findOrAddVertex is an internal method, users should use addTriangle instead
MiniCL includes a cross-platform run-time frontend based on pthreads, Win32 Threads, or libspe2 for Cell SPU.
It is there, to bridge the gap until OpenCL is more widely available.
See Bullet/Demos/VectorAdd, influenced by NVidia OpenCL Jumpstart Guide:
http://developer.download.nvidia.com/OpenCL/NVIDIA_OpenCL_JumpStart_Guide.pdf
It is disabled by default, see Demos/Gpu2dDemo/btGpuDemoDynamicsWorld.h for instructions how to enable it
Cleaned up Extras/CUDA folder and libbulletcuda project
For example, to only allow linear motion in the X-Z plane, and only rotation around Y axis use:
body->setLinearFactor(btVector3(1,0,1));
body->setAngularFactor(btVector3(0,1,0));
Fix build issues with CodeBlocks, when generating projectfiles using CMake 2.6:
${OPENGL_glU_LIBRARY} should be ${OPENGL_glu_LIBRARY}
Fix build issue with CodeBlocks, comment out xmlfree in Extras/COLLADA_DOM/src/modules/LIBXMLPlugin/daeLIBXMLPlugin.cpp (will leak memory)
Revert definition for ATTRIBUTE_ALIGNED16, and try to force sizeof(btSolverConstraint) by using unions with btScalar, for non-btScalar data types.
Use btAssert and not assert.
Don't access btAlignedObjectArray elements, for zero sets
