Bullet is an open source software multi-threaded 3D Collision Detection and Rigid Body Dynamics Library (physics engine). It is published under the zlib license making it free for commercial use. Its main author, Erwin Coumans, previously worked for the Havok project.

Features:
*collision shapes include: sphere, box, cylinder, cone, convex hull, and triangle mesh
*implements GJK convex collision detection
*solid sweep collision test
*continuous Collision Detection
*constraints
*COLLADA 1.4 Physics import
*modular approach supports home-brewed physics software
*Plugin for Maya 2008

Bullet provides rigid body dynamics for the Blender 3-D modeling, rendering, and animation package.

The Bullet website also hosts a [http://www.continuousphysics.com/Bullet/phpBB2/index.php Physics Forum] for general discussion around Physics Simulation for Games and Animation.
