Full implementation of the first Raytraing In One Weekend book (with additional ACES tonemapping), accelerated using Metal and the iPhone 15 Pro hardware raytracing features. Additional credit to Apple for the SimplePathTracer example project, which was an invaluable reference for the Metal raytracing API.
The code quality is not incredible as I chose compactness over abstraction, and there's an over-abundance of ! instead of proper error handling. Nevertheless, it serves as a decent reference for basic raytracing in Metal.
