f3a70b65eb Fix issues with btCompoundShape when adding/removing child shapes after construction of a btRigidBody. 
Thanks tp for the report:

635e1a6aa0 set broadphase handle to zero when destructing a btCollisionWorld, just in case a collision object/ rigid body is re-used. 
Thanks to Ole for reporting

Fix a bug , causing some deep penetrations to be missed. Not likely to have impacted many users, as such deep penetrations should have prevented in the first place.
Thanks a lot to Andy O'Neil for reporting and reproduction case.

b89b71b38d improving the SSE constraint solver performance: avoid a FPU/minus operation, by replacing a _mm_add_ps(-normal,X) by _mm_sub_ps(X,normal) 2008-12-03 17:40:01 +00:00

452fd24501 use 0.2 for erp, 0.4 makes stacks very spungy 2008-12-03 06:09:25 +00:00

a064fd2052 Use the opposite constraint axis inside the constraint solver for the second object (-normal). 
This makes it easier to port existing constraints and makes it 100% compatible with ODE quickstep constraint layout (getInfo2)

23bb0d94e6 documentation/parameter name fix for btMatrix3x3::setEulerZYX. There is no change in behaviour, no compatibility issues. 
Thanks Tully Foote for the patch.

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.

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:
