| | | | | In my previous two articles I discussed collision detection and response between rigid bodies. In order to do proper collision response between rotating objects, we needed to calculate the moment of inertia about their center of mass. Here I'm going to describe how to get the moment of inertia for | |

| | | | | One thing you may have noticed about the trigonometric functions sine and cosine is that they seem to have no agreed upon definition.
