258ef6e25a + Added joint feedback for constraints, needs testing/demo before 2.75 release.
See also http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2677
and http://code.google.com/p/bullet/issues/detail?id=227

To enable, use constraint->enableFeedback(true);
And then either use
constraint->getAppliedImpulse() for an estimated applied impulse,
or constraint-> getAppliedLinearImpulse(), or constraint->getAppliedAngularImpulseA() or constraint->getAppliedAngularImpulseB().

+removed a few warnings.

700db838b1 Add 1D and 2D support for Bullet: using rigidbody->angularFactor(const btVector3& factor) and body->setLinearFactor(const btVector3& linearFactor);
For example, to only allow linear motion in the X-Z plane, and only rotation around Y axis use:
	body->setLinearFactor(btVector3(1,0,1));
	body->setAngularFactor(btVector3(0,1,0));
Fix build issues with CodeBlocks, when generating projectfiles using CMake 2.6:
${OPENGL_glU_LIBRARY} should be ${OPENGL_glu_LIBRARY}
Fix build issue with CodeBlocks, comment out xmlfree in Extras/COLLADA_DOM/src/modules/LIBXMLPlugin/daeLIBXMLPlugin.cpp (will leak memory)

d886c06fa5 Add the option for the btSimulationIslandManager to avoid splitting islands (for constraint solving)
Move the convertContact inside constraint solver to its own method

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

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

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.

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

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.

bcd0f48c28 some doxygen updates, added some comments to classes, fix broken links, rename some prefix some internal GIMPACT collision structures using (for example use GIM_AABB instead of BT_AAABB),
removed obsolete btGjkEpa (it was replaced by btGjkEpa2 ages ago)

28e580c203 removed STL usage of Extras/ConvexBuilder and replaced by btAlignedObjectArray
fixed several warnings, thanks to sparkprime
added comments patch for linear math, thanks to Tully Foote
