sdfu - Signed Distance Field Utilities

This is a small crate designed to help when working with signed distance fields in the context of computer graphics, especially ray-marching based renderers. Most of what is here is based on Inigo Quilez' excellent articles.

If you're using one of the more popular math libraries in Rust, then just enable the corresponding feature and hopefully all the necessary traits are already implemented for you so that you can just start passing in your Vec3s or whatever your lib calls them and you're off to the races! If not, then you can implement the necessary traits in the mathtypes module and still use this library with your own math lib.
