2D and 3D physics engines for the Rust programming language.

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!


We update our roadmap at the beginning of each year. Our 2021 roadmap can be seen there. We regularly give updates about our progress on our blog.
