d419f79770 fixes to make MultiThreadedDemo work in 64bit, ParallelConstraintSolver won't work yet, only the parallel collision dispatcher 2011-04-03 19:30:26 +00:00

1fb2fa3db9 put an #ifdef in PosixThreadSupport in the right location 2011-04-02 20:13:50 +00:00

b16b61d9d6 disable constraints when they exceed a breaking threshold, control it with new methods in btTypedConstraint: get/setBreakingImpulseThreshold and get/setEnabled 
Disabled constraints are not removed from the world and they use negligible CPU cycles

b1f21a7e6a Add better support for btCollisionWorld::convexSweepTest for btStaticPlaneShape, now using the btContinuousConvexCollision directly. 
Bugfix in btKinematicCharacterController, using an uninitialized variable

5cee553a96 convexSweepTest: don't report hits if 'needsContactResponse' reports false. 
Should fixes Issue 197

0bef2e7363 Fixes in btContinuousConvexCollision, should fix Issue 347 
Continuous sweeps do not detect hits unless body0 and body1 penetrate more than allowedCcdPenetration.
This is to allow sliding objects (characters) where otherwise any contact would result in TOI = 0.
If objects penetrate deeper than allowedCcdPenetration at the start of the sweep, a TOI=0 is reported, unless the motion will separate the objects.

Secondly, a reportFailure method is added to CastResults, to handle failures gracefully (in case max iterations of conservative advancement is reached etc)

88b19eb023 fixes in PosixThreadSupport to enable ThreadingDemo and MultiThreadingDemo to run properly.

2a856f8c32 add support for clipFaceAgainstHull, so we can clip convex polyhedra against triangles (without connectivity information) 
in addition to the existing clipHullAgainstHull
Fix for debug drawing of contact points
comment-out some debug drawing code for triangle meshes

784e7fdb39 Added support for separating axis test for polyhedral shapes 
Added initial support for polyhedral contact clipping. 
This clipping takes a separating normal, that can be computed using either SAT or GJK/EPA.
To enable clipping, use btPolyhedralConvexShape::initializePolyhedralFeatures(); (needs to be enabled for both convex shapes)
No concave trimesh support for SAT/clipping yet. To enable SAT, see the toggle in btConvexConvexAlgorithm.
Fixes in contact normal in btGjkPairDetector. Hopefully this doesn't cause any regression (we need unit tests!)

f44cb95b2a Added improved convex hull computation utility based on Preparata and Hong 
Thanks to Ole Kniemeyer, MAXON, See also http://code.google.com/p/bullet/issues/detail?id=275
