48526b720c Fixes in Dynamica that let's Maya Plugin playback the simulation using Maya 2009 (used to only work with previous version). 
Thanks to Lawrence Chai from Disney Animation for the contribution.

e80feca36b Big work-in-progress refactoring of the constraint solver: 
1) Add fast branchless SIMD support for constraint solver (Windows only until we get other contributions).
See resolveSingleConstraintRowGenericSIMD in Bullet/src/BulletDynamics/ConstraintSolver/btSequentialImpulseConstraintSolver.cpp
resolveSingleConstraintRowGenericSIMD can be used for all constraints, including contact, point 2 point, hinge, generic etc.

2) During this refactoring, all constraints support the obsolete 'solveConstraintObsolete' while we add 'getInfo1' and 'getInfo2' support.
This interface is almost identical interface to Open Dynamics Engine, to make it easier to port Dantzig LCP solver.

3) Some minor refactoring to reduce huge constructor overhead in math classes.

Add Concave Convexcast demo back in AllBulletDemos, and tweaked it a bit.
Fix view frustum of ForkLiftDemo (caused picking to fail)

dc8692ba94 Added IBM Cell SDK 2.x software_cache to Bullet/Extras. There is an option to enable it for the BulletMultiThreaded Cell version. 
See USE_SOFTWARE_CACHE in Bullet\src\BulletMultiThreaded\SpuNarrowPhaseCollisionTask\SpuGatheringCollisionTask.cpp
It improves the Bullet midphase collision detection (triangle/vertex fetch)
The license is CommonPublicLicense-1.0, see included license docs.

d25d264e77 Improved CharacterDemo/KinematicCharacterController, dynamic objects will bounce off. 
Don't create a todo list for doxygen by default (the chaotic todo's would confuse most developers)
Improve support for small objects, by having dynamic contact breaking thresholds. Still needs small internal timestep and some GJK improvements.

erwin.coumans
2a721c7489 Updated original EA-IFF-85 files to read and write Interchange File Format files. 
Plan is to convert COLLADA XML into IFF, for faster, more compact and easier to read and parse files.
Reading/writing code is a few hundred lines of code, instead of COLLADA-DOM and libxml combo.
So it would be suitable as a run-time format for platforms ranging from iPhone to PlayStation 3.
Relevant physics data (and perhaps other data) will be converted from COLLADA -> IFF. 
We could call the resulting files COLLADA binary IFF -> CLIFF.

8f3e9603f3 + fixed issue related to temporary/root collision shape in btCollisionObject 
+ normalize plane normal input for btStaticPlaneShape
+ fixed issue related to swapped collision detectors (SphereTriangleDetector in particular)
Thanks a lot to Andrey Tuganov for reporting the issue and his reproduction case ( http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2143 )

d49aeb9dff + improved split impulse constraint solver option

+ made constraint solver configuration more consistent (moved m_solverMode into btContactSolverInfo)

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

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)

65bb612598 - added quickSort to btAlignedObjectArray (has generally better performance then heapSort) 
- replaced all usage of heapSort by quickSort
- finished btMultiSapBroadphase. Still some work to be done to increase performance (faster add/remove from child broadphases. 
  uses currently AABB tree to locate child broadphase (should use grid), and sorted array takes too much time.
