YARRR - Yet Another Rust Raytracer Rewrite

Study exercise in rewriting the famous Ray Tracing in One Weekend by Peter Shirley from C++ to Rust to practice the language. This is also my final project submission of the course OTUS Rust Developer.

Goals

• not looking at other numerous Rust implementations until im done with first complete implementaton
• not using 3rd party linear algebra libraries until im done with first complete implementaton
• practice writting organizing rust modules, writing tests and using CI like it was a production ready tool

Getting started

Run one of the examples

cargo run --release --example final_render
