Box3D is a brand new 3D physics engine from Erin Catto, the creator of the popular Box2D 2D physics engine. It's entirely open source, written in C, cross platform and full featured. It is built on top of Box2D + Valve's Rubikon physics. Always nice to have more options, especially free & open source ones!
