john.mccutchan a8ec916af0 Added Height Field Fluid Demo to Bullet. All code stored in the Demos/HeightFieldFluidDemo directory for now. 
Please see HfFluidDemo.cpp for examples of how to use the height field fluid along with buoyant collision shapes.

The implementation is still lacking in my ways:
1) Need to complete more collision algorithms for buoyant collision shapes
2) Support compound buoyant shapes
3) The buoyancy model isn't that great
4) Fluid volume can be lost over time

erwin.coumans 4be20dc347 BulletMultiThreaded optimization: remove some memory copy on non-SPU platforms, using cellDmaGetReadOnly. 2008-12-12 22:28:16 +00:00
erwin.coumans c541414c84 disable btDbvt::collideTT with transform, it is unused and uses an invalid Intersect method. 2008-12-09 06:21:19 +00:00
erwin.coumans 8ed2db9b42 finally applied this 'getGravity' patch, so getGravity matches setGravity.

erwin.coumans 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.

erwin.coumans 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

erwin.coumans 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.

erwin.coumans 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
erwin.coumans 6966b627a9 update ChangeLog 2008-12-03 06:20:23 +00:00
erwin.coumans 452fd24501 use 0.2 for erp, 0.4 makes stacks very spungy 2008-12-03 06:09:25 +00:00
erwin.coumans 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)

erwin.coumans 12a9a6e412 reverted patch, it breaks all the demos. 2008-12-02 22:32:45 +00:00
erwin.coumans 23bb0d94e6 documentation/parameter name fix for btMatrix3x3::setEulerZYX. There is no change in behaviour, no compatibility issues.

erwin.coumans 76b3e44117 Enable contact constraint in the obsolete/experimental SpuParallellSolverTask. It will be replaced by a better parallel constraint solver. 2008-12-02 07:39:13 +00:00
erwin.coumans 5383ed4930 + need to reset rigid body using 'setCenterOfMassTransform' to reset world inertia tensor

erwin.coumans 7341c6ee7e Minor fixes to keep trunk compiling, while doing the refactoring. 2008-12-01 06:55:27 +00:00
erwin.coumans 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.

erwin.coumans 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
rponom 09aa2dbbe7 CPU implementation of btCudaBroadphase added. 
It is called bt3DGridBroadphase and btCudaBroadphase is now derived from it rater than from btSimpleBroadphase

erwin.coumans 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.
