Fast 2D and 3D physics engine for the Rust programming language.
![[object Object]](/img/feature_contact_models.svg)
Multi-platforms physics simulations
Fast physics for games, animation and robotics. Runs cross-platform, including the official support of web platforms.
![[object Object]](/img/feature_multibody_and_constraints.svg)
Joint constraints
Constraint the relative motion of two rigid-bodies using force-based joints. Simulate ragdolls, robots, vehicles, etc.
![[object Object]](/img/feature_event_handling_and_sensors.svg)
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.

WebAssembly and JavaScript
Use our official NPM packages published behind the @dimforge namespace and run Rapier in any modern browser.
![[object Object]](/img/undraw_determinism.svg)
Cross-platform determinism
Optionally make Rapier cross-platform deterministic on all IEEE 754-2008 compliant 32- and 64-bits platforms.
![[object Object]](/img/undraw_open_source.svg)
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.
