This is my Ray Tracing in One Weekend implementation using Rust.
I also improved the render times by paralelizing the code and added a CLI.
This is the render that it produces by default:

More of them are in the images folder.

Ray Tracing in a Weekend implementation in Rust
USAGE:
ray-tracing [FLAGS] [OPTIONS] <scene>
FLAGS:
--avoid_bvh Avoid to build a BVH with all the objects. May be faster to render a simple scene.
-d, --debug Increases the logging level.
-h, --help Prints help information
--plain_ppm Use plain ppm format, enconding the image into an ASCII ppm file.
--stdout Returns the image via the standard output, not saving it to a file.
-V, --version Prints version information
OPTIONS:
--aspect <ASPECT_RATIO> Aspect ratio of the image. Format: <width>/<height> e.g. "16/9"
-F, --format <format> Explicitly select image format, if not given it's inferred from output file
extension.
--resolution <HEIGHT> Vertical resolution of the image
-o, --output <output> File to output to.
--raydepth <RAY_DEPTH> Maximum ray depth. More depth, more reflects and refractions but more computation.
--spp <SPP> Samples per pixel. More samples, less noise but more computation.
-j, --threads <threads> Number of worker threds to use. Defaults to the number of physical cores available.
ARGS:
<scene> [possible values: spheres, bouncing_spheres, checker_ground, checker_spheres, perlin_spheres, earth,
black, simple_light, cornell_box, cornell_smoke, final_scene]
- cbiffle/rtiow-rust has helped me to achieve a much faster aabb hit function.
- skyzh/raytracer.rs has helped me with the memory layout without so many references, using generics.
