The Bullet physics engine lets you create large-scale, highly-realistic dynamic and kinematic simulations. You can use Bullet to create content for rendered animations for film and visualization, as well as for the setup of game engine and real-time simulations.
The Bullet plug-in provides seamless mapping of Bullet objects to Maya objects. The controls to the Bullet objects are exposed in Maya Objects, and the interaction follows the typical Maya dynamics paradigm. Bullet Physics is an open-source collision detection, rigid body and soft body dynamics library. The library provides a collection of objects each corresponding to the various aspects of dynamic simulations. For example, the Bullet solver, rigid bodies, soft bodies and constraints are all unique Bullet objects.
