 2011-04-01 16:33:55 +00:00
erwin.coumans 08a93b28f0 re-introduce the radius/epsilon removed in a previous commit, it is necessary for termination. 2011-03-31 21:54:26 +00:00
erwin.coumans 5cee553a96 convexSweepTest: don't report hits if 'needsContactResponse' reports false. 
Should fixes Issue 197
 2011-03-31 21:20:52 +00:00
erwin.coumans 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)
 2011-03-31 21:14:35 +00:00

erwin.coumans 8847b21eb7 fix for gcc/ubuntu 2011-03-29 09:12:35 +00:00
erwin.coumans 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!)
