3ca977e39f Patch by Nathanael Presson: (needs some more work, some of the demos don't show properly (RayCaster, CollisionInterfaceDemo,'g' key is already occupied in ConcaveDemo etc) 
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.

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

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)
