Tokamak physics engine

The Tokamak Game Physics SDK is an open-source physics engine
.
At its beginnings, Tokamak was free for non commercial uses only. Since May 2007, it has become open sourced under a BSD License

involve solving large matrices, thereby avoiding memory bandwidth limitations on some game consoles.
The SDK supports a variety of joint types and joint limits and a realistic friction model. Tokamak is optimized for stacking large numbers of objects - a frequently requested feature by game developers. Tokamak provides collision detection for primitives (box, sphere, capsule), combinations of primitives, and arbitrary static triangle meshes. Lightweight 'rigid particles' provide particle effects in games at minimal cost.
Tokamak also supports "Breakage Constructing models" which will break when a collision occurs. Fragments of the original model will automatically be spawned by Tokamak's built-in breakage functionality.
Physics engine
A physics engine is computer software that provides an approximate simulation of certain physical systems, such as rigid body dynamics , soft body dynamics, and fluid dynamics, of use in the domains of computer graphics, video games and film. Their main uses are in video games , in which case the...

Features
Tokamak features a unique iterative method for solving constraints. This is claimed to allow developers to make trade-offs between accuracy and speed and provides more predictable processor and memory usage. Tokamak's constraint solver does notinvolve solving large matrices, thereby avoiding memory bandwidth limitations on some game consoles.
