You just want to find the moment of inertia for a 2D polygon? That's really easy actually. Here's how I do it in Chipmunk (cpMomentForPoly): http://aerosol.googlecode.com/svn/trunk/Chipmunk/src/chipmunk.c I'll see if I can dig up a link with the original equation. edit: Wikipedia is always a good ch...

are those videos recorded in real-time? that looks pretty amazing! No. I used a ton of iterations and extra substeps to make the stacks as stable as possible. The irony is that I used those videos for my senior seminar presentation on realtime rigid body physics. The first movie with the small pyra...

Yet another 2D physics library utilizing the Box2D impulse solver! I'll not waste too much breath here, there's plenty of info on the homepage: http://wiki.slembcke.net/main/published/Chipmunk I've been working on this in my free time since September. The big features: Poly, circle, and segment coll...
