Multi-platforms physics simulations
Fast physics for games, animation and robotics. Runs cross-platform, including the official support of web platforms.
Constraint the relative motion of two rigid-bodies using force-based joints. Simulate ragdolls, robots, vehicles, etc.
Contact events and scene queries
Handle collision and intersection events or use scene queries to perform ray-casting, sweep-tests, intersection tests, etc.
SIMD and parallelism
Optionally enable SIMD optimizations and/or parallelism to get the best performance your CPU can offer to simulate complex scenes.
Use our official NPM packages published behind the @dimforge namespace and run Rapier in any modern browser.
Optionally make Rapier cross-platform deterministic on all IEEE 754-2008 compliant 32- and 64-bits platforms.
Forever free and Open-Source
Built with a FOSS mindset, we aim to empower the Rust and web communities with an efficient physics simulation framework.
