Bullet is an open source physics engine featuring 3D collision detection, soft body dynamics, and rigid body dynamics. It is used in games, and in visual effects in movies. The Bullet physics library is published under the zlib license. Erwin Coumans, its main author, worked for Sony Computer Entertainment US R&D from 2003 until 2010. He now works for AMD.

[edit] Features

  • Rigid body and soft body simulation with discrete and continuous collision detection
  • Collision shapes include: sphere, box, cylinder, cone, convex hull using GJK, non-convex and triangle mesh
  • Soft body support: cloth, rope and deformable objects
  • A rich set of rigid body and soft body constraints with constraint limits and motors
  • Plugins for Maya, Softimage, integrated into Houdini, Cinema 4D, LightWave 3D, and Blender and import of COLLADA 1.4 physics content
  • Optional optimizations for PlayStation 3 Cell SPU, CUDA and OpenCL[2]

The Bullet website also hosts a Physics Forum for general discussion around Physics Simulation for Games and Animation.

[edit] Projects using the engine

[edit] Commercial games

Games using Bullet created by professional game developers for video game consoles or other platforms include:

[edit] Movies

Several Hollywood movie studios are using Bullet rigid body simulation for special effects in commercial films. Movies using the Bullet engine include:

[edit] 3D Authoring tools

  • Blender -- A free 3D production suite that uses Bullet physics for animations and its internal game engine Game Blender.
  • Carrara Pro added Bullet Physics in version 8 (only included in the Pro edition).[20]
  • Cheetah3D, a 3D modeling, rendering and animation software for Apple Mac OS X uses the Bullet physics engine to simulate rigid body and soft body dynamics. (As of version 6.0.)
  • Cinema 4D version 11.5 uses Bullet as part of MoDynamics.[21]
  • Houdini has native Bullet Physics support in the dynamics context as of version 12. Available as an community supported open source plugin for previous versions.
  • LightWave 3D CORE.[22]
  • Modo Recoil Allows users to simulate dynamic rigid body interactions based upon the popular Open Source Bullet Physics Library
  • MikuMikuDance a freeware 3D animation program, added the use of Bullet Physics Engine in version 5
  • Softimage plugin Momentum developed by Helge Mathee and distributed by Exocortex
