ray-tracer

Implementation in Rust of a ray tracer following The Ray Tracer Challenge book.

The renderer is a ray tracer, which means it simulates the physics of light by tracing the path of light rays around your scene. 
Each exciting chapter presents a bite-sized piece of the puzzle, building on earlier chapters and setting the stage for later ones.
Requirements are given language-agnostically; it’s up to you to translate them into tests and code using whatever language you prefer.
When the project is complete, you’ll look back and realize you’ve built an entire system test-first!

Hacking

Performance profiling

The code can be profiled to remove bottlenecks and keep the rendering fast as features are added.

cargo install flamegraph to install https://github.com/flamegraph-rs/flamegraph

then inside the project directory we can profile cargo run --release by running cargo flamegraph

Latest flamegraph.
