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.

82047e601e updated Bullet sequential impulse constraint solver, so it matches 100% ODE PGS quickstep solver innerloop, mainly by renaming variables... 2008-11-26 00:27:35 +00:00

09aa2dbbe7 CPU implementation of btCudaBroadphase added.
It is called bt3DGridBroadphase and btCudaBroadphase is now derived from it rater than from btSimpleBroadphase
Test of bt3DGridBroadphase was added to CDTestFramework

decf91a34d Made btCollisionWorld::convexSweepTest and btGhostObject::convexSweepTest consistent. Both have an optional last argument for allowedCcdPenetration.
Bugfix due to recent change in friction in constraint solver.

50344c4a23 Add support for broadphase acceleration of convex cast (re-use rayTest implementation with an added aabb min/max, zero for rays)
Add Concave Convexcast demo back in AllBulletDemos, and tweaked it a bit.
Fix view frustum of ForkLiftDemo (caused picking to fail)
Removed innerloop profiling for ray and convex casts, it hurts performance.
Set default #aabb's in CDTestFramework to 8192

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.

fe461296c6 Fix issue with un-initialized broadphase proxy during broadphase insert. It was an chicken-egg problem:
1) creating a broadphase proxy -> adding pairs during insertion. But during this pair insertion, the btGhostObject broadphase handle isn't set yet (it is done in step 2)
2) assign the broadphase proxy to btGhostObject

686accab16 + repaired SpuParallellSolverTask: support for warmstarting and added btAssert for constraint sizes that exceed CONSTRAINT_MAX_SIZE
+ Share some more code between SpuParallelSolver and btSequentialImpulseConstraintSolver (both use btSolverBody now)
Lack of warmstarting reported here: http://bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2858
+ allow btBoxBoxDetector to execute on SPU.
