What is Rapier?

Rapier is a set of 2D and 3D physics engines for games, animation, and robotics. These crates are rapier2d, rapier3d, rapier2d-f64, and rapier3d-f64. They are written with the Rust programming language, by the Dimforge organization. It is forever free and open-source!

Getting started

The easiest way to get started with Rapier is to:

1. Read the user-guides.
2. Play with the examples: cargo run --release --bin all_examples2 and cargo run --release --bin all_examples3. Their source code are available on the examples2d/ and examples3d/ directory.
3. Don't hesitate to ask for help on Discord, or by opening an issue on GitHub.

AI coding disclaimer and policy

AI coding is extensively used for the implementation and maintenance of the following crates: mjcf-rs, rapier3d-mjcf.

We actively use AI assistance (with human reviews) for the following tasks: - Documentation generation. - Changelogs generation. - Tests generation. - CI configuration and scripts.

We accept contributions involving AI coding as long as: - They are verified to work properly by a human. - The code quality is up to human-written code standards. - Include non-regression tests whenever applicable (which itself can be AI-generated).
