[not being worked on anymore] Toy ray marcher inspired by tinyraytracer, with a couple of changes or additions: written in Rust (first project for me, so probably very naive), and taking some multispectral components into account (well, R/G/B indices for everything from reflexion/refraction/diffusion/lighting).

Only dependencies are the awesome Rayon and tiny obj loader, on purpose (programming exercise, again..), plus the GTK toolkit if you want to build the naive UI.

How to run: cargo run to get the demo scene rendered.
