A ray tracer in rust. Based on Peter Shirley's Ray Tracing in One Weekend.
I posted the link to this repo on /r/rust and folks suggested that I run in release mode (I was running in debug mode the whole time). This significantly improved the runtime.
There's also a progressbar while rendering/saving now, thanks to coder543's Pull Request.
A 480x320 image at 1000 samples took around 23 minutes to render.
PS: Hence proved. Rust has an awesome community.
Multi-threaded implementation using Rayon. 480x320 image at 100 samples took around 46 minutes to render.
Single-threaded implementation complete. 1200x800 image at 10 samples took nearly 6 hours to render.
Image generated after running 504 random spheres at 1000 samples.
