    Use Cases & Benefits

    • Provides an ECS-driven 2D and 3D physics engine tightly integrated with the Bevy game engine.
    • Offers a modular, ergonomic API designed specifically for Bevy without wrapping external engines, enabling seamless physics integration.
    • Use for developing physics-based 2D games with dynamic and static rigid bodies in Bevy using Rust.
    • Use for creating 3D simulations with advanced collision detection, joints, and spatial queries in Bevy projects.
    • Use for extending or customizing physics behavior in Bevy games via its plugin architecture and support for custom collision backends.
