Re: CPU multithreading is working!

I've run into a problem when using constraints with kinematic bodies (simulated bodies work fine). btSimulationIslandManagerMt calls buildAndProcessIslands(), which calls addConstraintsToIslands(), which calls btGetConstraintIslandId(), which returns -1. The next line, "Island* island = getIsla...

Questions about implementing contact and overlap callbacks

I need three callbacks. A callback when objects initially contact, regardless of whether they overlap, and begin/end overlap callbacks. Ghost objects won't work because they are only for broadphase collision. Also, they seem really inefficient when used with rigid bodies. There are more collisions t...
