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

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

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.

29bfd06af7 Disable friction warmstarting by default, removing second friction direction. This gives a large performance increase. 
friction warmstarting can be turned on using:
dynamicsWorld ->getSolverInfo().m_solverMode |= SOLVER_USE_FRICTION_WARMSTARTING;

Thank for the report mi076 http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2823

remove legacy.c from libxml
removed #include <math.h> from btQuadWord.h , it should be centralized in btScalar.h (to allow easier replacement with fastmath.h etc)

463a1b74c1 The SPURS version requires 16-byte alignment at the moment, and Cell SDK doesn't, so keep it like this for 2.73. @todo: Need to figure out better way to deal with those differences. 2008-11-09 23:35:23 +00:00
