Bullet (software)
Bullet is a physics engine which simulates collision detection, soft and rigid body dynamics. It has been used in video games as well as for visual effects in movies. Erwin Coumans, its main author, won a Scientific and Technical Academy Award[4] for his work on Bullet. He worked for Sony Computer Entertainment US R&D from 2003 until 2010, for AMD until 2014, and he now works for Google.

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, Blender and Godot and import of COLLADA 1.4 physics content
- Optional optimizations for PlayStation 3 Cell SPU, CUDA and OpenCL[6]
The Bullet website also hosts a Physics Forum for general discussion around physics simulation for games and animation.
At AMD Developer Summit (APU) in November 2013 Erwin Coumans presented the Bullet 3 OpenCL Rigid Body Simulation.[7][8]
