6db1b932fd Make the btDbvtBroadphase deterministic/reproducable, by sorting the btBroadphasePair using unique ID, instead of proxy address. 
The btAxisSweep3 didn't suffer from this issue, because proxies were always allocated in-order, as part of an array.

65cdd7146f Use placement new for copy constructor of arrays. Thanks to M. Reuvers for the patch. 
http://bulletphysics.com/Bullet/phpBB3/viewforum.php?f=9

Generally, however, it is best to avoid copying entire arrays, but use a 
reference.

typedef btAlignedObjectArray<btSomeClass> Array;

Array a;
Array b = a;//avoid this whenever possible

This is much better:
Array& b = a;//use a reference
const Array& b = a; //or const reference

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

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)

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.

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

Lack of warmstarting reported here: http://bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2858
+ allow btBoxBoxDetector to execute on SPU.
