+ improved friction warm starting
+ made constraint solver configuration more consistent (moved m_solverMode into btContactSolverInfo)
+ reset timing in CDTestFramework after initialization (SAP init destorts timings)
+ make it easier to change default sizes for stack allocator in btDefaultCollisionConfiguration
virtual void getAllContactManifolds(btManifoldArray& manifoldArray)
See Demos/CharacterDemo/CharacterDemo.cpp for example usage of getAllContactManifolds
Added btDbvtBroadphase to btBulletCollisionCommon.h headerfile
Enable soft body vs concave (albeit slow)
Improved contact point debug rendering (moved from constraint solver into debugDrawWorld)
+ fixed issue with persistent manifold, warmstarting values were not initialized properly
+ don't clear manifold in sphere-sphere collision (need warmstarting)
+ added support for 'split impulse', decouple positional error correction from velocity correction
This avoids adding momentum due to penetration correction, it can be tuned using following variables:
solverInfo.m_splitImpulse = true/false (disable/enable)
solverInfo.m_splitImpulsePenetrationThreshold (below this value, baumgarte/mixed velocity/penetration is used (cheaper, looks more plausible)
solverInfo.m_linearSlop (less jitter, when small amound of penetration is allowed)
+SoftBody improvements by Nathanael Presson:
+Add tetrahedralization
+Add support for tearing/slicing cloth and deformable volumes. Uncomment the line in Bullet/src/BulletSoftBody/btSoftBodyHelpers.h: //#define BT_SOFTBODY_USE_STL 1
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)
+ use btBroadphaseProxy::AllFilter to collide with static and dynamic rigidbodies in broadphase
+ enlarge aabb for softbody in broadphase, otherwise misses collisions (deformation is not updated in-time?)
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.
