# Ray Tracing in One Weekend in Rust

This is my [Ray Tracing in One Weekend](https://raytracing.github.io) 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:

![Cornell box](./images/cornell_box.png)

Other examples:

![Book one final scene](./images/random_spheres.png)

![Book two final scene](./images/final_scene.png)

More of them are in the [images](./images) folder.

## CLI

```

Ray tracing renderer 0.1.0

Ray Tracing in a Weekend implementation in Rust

USAGE:

    ray-tracing [FLAGS] [OPTIONS] 

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 of the image. Format: /  e.g. "16/9"

    -F, --format           Explicitly select image format, if not given it's inferred from output file

                                   extension.

        --resolution       Vertical resolution of the image

    -o, --output           File to output to.

        --raydepth      Maximum ray depth. More depth, more reflects and refractions but more computation.

        --spp                 Samples per pixel. More samples, less noise but more computation.

    -j, --threads         Number of worker threds to use. Defaults to the number of physical cores available.

ARGS:

         [possible values: spheres, bouncing_spheres, checker_ground, checker_spheres, perlin_spheres, earth,

               black, simple_light, cornell_box, cornell_smoke, final_scene]

```
