Worthy physics engines

  • Box2D -- 2D physics engine, notable for "contact persistence algorithm".
  • Chipmunk -- 2D physics engine, inspired by Box2D. Fast and simple, written in C.
  • Bullet -- 3D engine, shares many of the same algorithms and concepts with Box2D.
  • Haskell Bullet -- simple haskell binding for Bullet
  • ODE -- popular 3D engine, written in C++.
  • Physsim -- modular 3D engine, written in C++. Inspired by ODE.

Modular physics engine architecture

core simulator

Combines all other components to perform simulation.


Method used to integrate ODE.

Physsim implements Euler and Runge–Kutta (implicit and explicit) methods.

collision detector

Algorithm which detects whether the two bodies overlap.
