92dabdc07d Fix a couple of bugs in 2dConvex Hull algorithm.

* Need to handle case where the first tripple of points is non-convex,
previously this would cause the algorithm to fail with only 1 point.

b1863f7ce2 Refactored GJK, EPA and MPR as a template class, reducing/removing the dependencies 
to the rest of the Bullet code base. This code will replace the original GJK/EPA
in a future commit.

Added btMprPenetration, an implementation of Minkowski Portal Refinement
by Daniel Fiser. Original MPR idea is by Gary Snethen, and the first
implementation is here: https://github.com/erwincoumans/xenocollide
It is an alternative to EPA, although computing the local penetration depth.
EPA computes the global penetration depth. In many cases, MPR is sufficient
and performs better than EPA.

It is tested in Aero2 demo (13) of AppSoftBodyDemo. Note that the cloth in Areo2 is not expensive enough to see benefits. Increase segments to see benefits.

5ce0b3938f Re-introduce GPU parallel Jacobi solver, called btGpuJacobiContactSolver. There are still some issues, but for basic scene's it works. 
To avoid confusion, rename GPU contact solver to btGpuContactSolver, and constraint (non-contact) solver to btPgsConstraintSolver.

218d4d1394 use a separate default cfm for the MLCP solver, it is a very sensitive value for Dantzig (and Lemke) 2013-10-31 16:52:32 +00:00

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)

6ca948e22f make Lemke work with lower/upper bounds, using the BLCP to LCP conversion (using a dog-slow matrix inversion etc) 
for this conversion, see also https://github.com/erwincoumans/num4lcp/blob/master/matlab/test_lcp_bounds.m and
appendix A1 in http://www.cs.duke.edu/~parr/nips10.pdf, thanks to Kenny Erleben and Evan Drumwright for the tips!

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,

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)
