//! # Rapier
|
|
//!
|
|
//! Rapier is a set of two Rust crates `rapier2d` and `rapier3d` for efficient cross-platform
|
|
//! physics simulation. It target application include video games, animation, robotics, etc.
|
|
//!
|
|
//! Rapier has some unique features for collaborative applications:
|
|
//! - The ability to snapshot the state of the physics engine, and restore it later.
|
|
//! - The ability to run a perfectly deterministic simulation on different machine, as long as they
|
|
//! are compliant with the IEEE 754-2008 floating point standard.
