2008-07-09 00:08:49 +00:00
erwin.coumans db146019f1 Fixed debug drawing for btCapsuleShapeX and btCapsuleShapeZ 2008-07-02 23:07:27 +00:00
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)

2008-05-29 03:33:32 +00:00
erwin.coumans 88ee734bfb added custom memory allocator registration, thanks to Sly.
call CProfileManager::CleanupMemory(), to cleanup btQuickprof memory.
changed include from #include <new.h> to #include <new> in btOdeQuickstepConstraintSolver.cpp
2008-05-24 06:10:09 +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
rponom 6141a55f09 Added linear and angular motors for the slider constraint 2008-05-23 22:52:51 +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)
2008-05-23 09:05:37 +00:00
erwin.coumans bd97c5e569 Fixed warnings in Bullet/src core library
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
2008-05-10 18:00:21 +00:00

erwin.coumans 1139c06a4d more soft body preparations, moved some parts from Demo/SoftBody to src/BulletDynamics/SoftBody
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)
2008-04-10 20:00:41 +00:00
erwin.coumans b32d6f790f added btInternalTickCallback, see btDynamicsWorld::setInternalTickCallback

erwin.coumans 569a949ae3 fixes in btQuaternion::inverse, fixed in btConeTwistConstraint, RagdollDemo and BenchmarkDemo.
Some constraint limits for btConeTwistConstraint might need to flip sign now.
2008-04-07 21:58:36 +00:00
erwin.coumans ed3e909282 some more fixes for btSoftBody:
+ use btBroadphaseProxy::AllFilter to collide with static and dynamic rigidbodies in broadphase

2008-04-06 08:22:46 +00:00
erwin.coumans b37a37a28e Added initial broadphase support for softbody versus softbody and softbody versus rigidbody (see btSoftSoftCollisionAlgorithm and btSoftRididCollisionAlgorithm)
