Ray Tracing in One Weekend - Rust

A Rust implementation of Peter Shirley-s amazing tutorial - link.

This was done for the sole reason of learning Rust via an actual project, so don't expect the code to be 100% idiomatic (or good, for that matter :)). Apart from the tutorial itself, parallel processing was also added using the rayon crate.

Building and running

Build the program using cargo build --release.

Then you can run the ray tracer, which outputs the image in PPM format to the standard output. You can redirect this image to a file:

./target/release/raytracing-one-weekend > image.ppm

Rendering the full image may take a while, took about 1.5 minutes on my poor little laptop :D The max_depth and samples_per_pixel parameters can be tuned to make the image more detailed, requiring more processing time.

Rendering of the final image (using parallel processing via rayon):

❯ cargo build --release
   Compiling rust-raytracing-in-one-weekend v0.1.0 (/home/ardi/projects/rust-raytracing-in-one-weekend)
    Finished release [optimized] target(s) in 0.86s
❯ ./target/release/rust-raytracing-in-one-weekend > image.ppm
Rendering took 91032 ms.
