ejcoumans 3fe3b11924 use Dispatcher in ConcaveConvexCollisionAlgorithm (so it uses the registered collision algorithm, not hardcoded convexconcave) 
improved performance of constraint solver by precalculating the cross product/impulse arm
added collision comparison code: ODE box-box, also sphere-triangle
added safety check into GJK, and an assert for AABB's that are very large
write partid/triangle index outside of GJK

ejcoumans 33b3ec94f1 more fixes, related to introduction of btMotionState, and using realtime timestep 2006-10-18 04:01:07 +00:00
ejcoumans 3a6942fb91 processed a lot of feedback: added 'realtime' simulation with fixed substeps (and clamping maximum number of substeps), this means that when stepSimulation is called with smaller timesteps then 'fixed substep' the motionstate is interpolated.
