Bullet is a free physics engine that supports 3D collision detection , simulation of rigid body physics, and simulation of non-elastic physics with deformations. It is used in computer game development and for visual effects in films. The Bullet Physics Library is published under the Zlib license . Lead author Erwin Coumans worked for Sony Computer Entertainment in North America from 2003 to 2010, for AMD until 2014 and currently works for Google .

features

• Simulation of rigid body physics ( rigid body dynamics )
• Simulation of non-elastic physics of fabrics, ropes and deformable objects ( soft body dynamics )
• Discrete and continuous collision detection .
• The following shapes are supported for collision detection : sphere , cuboid or cube (box) , cylinder , cone , convex envelope using the GJK distance algorithm , non-convex objects and triangular networks .
• A wide range of constraints ( constraints ) for the behavior of the objects.
• Plug-ins for Maya , Softimage , integrations for Houdini , Cinema 4D , LightWave 3D and Blender as well as an import option for COLLADA 1.4 physics content.
• Optional optimizations for the PlayStation 3 Cell SPU, CUDA and OpenCL .
