Rapier is a set of 2D and 3D physics engines written using the [Rust programming language](https://www.rust-lang.org/).
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.
- Contact events and sensors.
- Snapshotting.
- Optional cross-platform determinism.
- JavaScript bindings.
- And more…
