About Rapier

Rapier is a set of 2D and 3D physics engines written using the Rust programming language. It targets applications requiring real-time physics like video games, animation, and robotics. It is designed to be fast, stable, and optionally cross-platform deterministic. Rapier features include:

• Rigid-body collisions and forces.
• Joint constraints.
• Soft-bodies, i.e., ropes, cloth, and deformable solids.
• Contact events and sensors.
• Snapshotting.
• Optional cross-platform determinism.
• JavaScript, C, and Python bindings.
• And more…

The user guide of this website covers the Rust API, the bevy_rapier plugin, and the JavaScript/TypeScript, C, and Python bindings. Each page of the guide can be read for any of them, with the selector on top of the page.
