erwin.coumans 8028fa4999 debug draw contact numbers in black, not green (hurts the eyes) 2008-05-29 05:37:50 +00:00
erwin.coumans d49aeb9dff + improved split impulse constraint solver option 
+ 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)

 2008-05-24 06:10:09 +00:00
erwin.coumans 3a94e70370 don't enable concave mesh for soft body demos (work-in-progress) 2008-05-24 05:32:54 +00:00
erwin.coumans 3d32cf7ddf add penetration depth solver for btCollisionWorld::convexSweepTest, to handle touching/penetrating contact (useful for character controller) 2008-05-24 05:22:41 +00:00
erwin.coumans f8e5481612 Added method to collect all persistent contact manifolds, given a btBroadphasePair (collision algorithm) 
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)
 2008-05-24 04:23:00 +00:00
erwin.coumans a1578accac more work on soft body versus concave trimesh 2008-05-23 18:50:41 +00:00
erwin.coumans 561066af75 + make compound versus soft body work (soft body uses interpolated transform) 
+ 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)
