This is my first time attempting a ray tracing renderer! This work is based on Ray Tracing in One Weekend.

You can simply run

cargo run -- --help

and the program will output information on how to use it. You can tweak the output directory, output file name, and scene type (from the only two available default scenes basic and complex). The program will output a png file at the requested location, and will try to open it using feh for visualization.

The configuration for the maximal number of ray bounces, the number of antialiasing samples, and the image dimensions can be found at src/camera.rs. For the following examples, I use an image resolution of 1024 by 576.

Using 20 antialiasing samples and a maximum of 8 bounces, we can render (in release mode) in less than a second the following basic scene:

cargo run --release -- --scene=basic

For a more interesting scene we can get the following result in about 20 seconds:

cargo run --release -- --scene=complex

If you have the time and patience, however, you can render a big boy like the following in about 7 minutes (with dimensions 1200 by 800, 500 antialiasing samples, and 50 bounces):
