3a94e70370 don't enable concave mesh for soft body demos (work-in-progress) 2008-05-24 05:32:54 +00:00

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)

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)

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

6989ea8908 upgrade version to 2.69
moved btDbvt/btDbvtBroadphase to BulletCollision/BroadphaseCollision
applied code-layout to btSoftBodyHelpers.*

25c5d0d57a +Added btDbvtBroadphase, this very fast/efficient broadphase is based on Dynamic AABB tree (btDbvt).
+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

be2490e4fb Final 2.68 from Nathanael Presson, mainly soft body related. Added raycast support for soft bodies (press comma-key in the soft body demos to toggle ray cast tests) 2008-04-14 06:24:56 +00:00
