A Rust implementation of Peter Shirley's Ray Tracing in One Weekend.
I recommend building in release mode, as it speeds the rendering up significantly.
cargo build --release
Upon running the program, a progress bar powered by indicatif will show the rendering progress per scanline.
The image above rendered in ~22 minutes on a laptop equipped with an AMD Ryzen 5 4500U. It was rendered at a resolution of 1200x800 with 1000 samples per pixel and a maximum of 50 bounces. It renders significantly faster on the next-week branch where a BVH is implemented.
In order to improve performance, I used vector classes from nalgebra and scanlines are rendered in parallel using rayon.
I plan on working through the other books in the series as well, where I hope to get another significant speedup from implementing some spatial acceleration structure.
