# Ray Casting for Bevy

[![Bevy tracking](](

A [Bevy]( plugin for 3D ray casting against meshes. Used to build [`bevy_mod_picking`]( Contributions welcome!

## Uses

This plugin makes it simple to create ray casting sources, such as a transform (first person, third person shooter), or screenspace coordinates (mouse picking). Rays are shot from these sources every frame using a bevy system, and the intersections are stored in the ray casting source's component. 

- Only meshes that you mark with a component will be checked for intersections. 
- You can define which ray casting source(s) should interact with which mesh(es) by marking grouped sources and targets with the same type. 
- This plugin also provides some functionality to compute the intersection of rays with primitive shapes.
- Rudimentary acceleration is provided with opt-in bounding spheres.

## Bevy Version Support

I intend to track the `main` branch of Bevy. PRs supporting this are welcome!
