31998c8e7d minor issues (don't use \n in B3_PROFILE, and don't report timing inaccuracy in console 2014-01-29 15:25:36 -08:00

6142bdca0a brDefaultMotionState::getWorldTransform was wrong, in case of a non-identity centerOfMassOffset.
Thanks to Mathias for the report/fix.

69e5454d18 Add the old Bullet 2.x obsolete demos, and CMake buildsystem files, and gradually move them to newer Bullet 3.x structure
Use statically linked freeglut, instead of dynamic glut for the obsolete Bullet 2.x demos
Add the 'reset' method to b3GpuDynamicsWorld, and use it in the BasicGpuDemo (pretty slow in debug mode, use release mode)
Don't crash in btCollisionWorld, if there is no collision dispatcher

644d01d231 added the btNNCGConstraintSolver, based on the paper "Nonsmooth Nonlinear Conjugate Gradient Method for interactive
contact force problems". The solver needs a lot of iterations, before the quality goes up (~ 1000)
Thanks to Gabor PUHR for the contribution!
Improved the btLemkeSolver.
Remove the sparse optimizations from the btMatrixX.h, replace it with explicit call to rowComputeNonZeroElements (only used in the btSolveProjectedGaussSeidel), it was likely slowing things down, without being useful.
Re-enable SIMD in the solver (was accidently disabled in Bullet 2.82 release)

1a2c3c0ee9 Added a Lemke MLCP solver, extracted from the MBSim project, and re-licensed under the zlib license
with permission of the original author. 
The Lemke implementation is not fully working yet:
1) we need to convert the lo-high LCP problem into a problem without the lo/high
2) we need to sort out the remaining instabilities, and report a failure if the max loopcount is reached etc.
We replaced the fmatvec library with our own LinearMath/btMatrixX.h, and STL std::vector with btAlignedObjectArray

Removed some warnings/potential issues: use fuzzyZero instead of isZero, and some warnings,

379f0079e0 Added Dantzig MLCP solver option from Open Dynamics Engine (trying to avoid naming/linking conflicts in case ODE and Bullet is used together)
If an MLCP solver fails, use PGS/SI fallback, add a boolean return value for 'solve' method

1ca0493dc4 Build full A matrix and b vector for a MLCP solver interface, to explore Lemke, Dantzig, Newton and other MLCP solvers. The A matrix contains sparsity information.
Added a PGS solver that uses the sparsity of the A matrix, just for testing (the equivalent sequential impulse solver is much faster, not having to allocate the big matrices)

f02dd51597 Added a first version of a Featherstone multi body implementation.
The original version was written by Stephen Thompson.
I replaced Eigen math by Bullet LinearMath, and added a dedicated 6x6 matrix solver. 
Also I integrated support for collisions/contact constraints between btMultiBody and btRigidBody, and de-activation support.
See Demos/FeatherstoneMultiBodyDemo/Win32FeatherstoneMultiBodyDemo.cpp for example usage.
There is currently only support for contact constraints for btMultiBody. 
Next on the list will be adding support for joint limit constraint for btMultiBody. 
The implementation is still experimental/untested, the quality will improve in upcoming Bullet releases.

6fd4738a9e use the old data structures for single precision serialization, to make it backwards compatible
So files created by the new double precision serialization of Bullet 2.82 cannot be read by old Bullet versions,
but double precision serialized file generated by older Bullet versions can be read by Bullet 2.82 or newer.

1aac33f6b6 refactor constraint serialization, so that double precision is maintained,
changes are backwards compatible (btBulletWorldImporter can load old .bullet files)
but not forwards compatible (constraints in new .bullet files are ignored/unrecognized by old Bullet SDK)
This commit is for Issue 734. Some more work needs to be done for btGImpactMeshShapeDoubleData and thus btStridingMeshInterfaceDoubleData and btMeshPartDoubleData

e792f0e549 Add faster processing of btCompoundShape versus btCompoundShape, using a dedicated btCompoundCompoundCollisionAlgorithm,
with hash pair caching and tandem tree traversal. It should be much faster, when using many child shapes for both compounds.
