That raytracer is impressive. For a gentle introduction to raytracing, I recommend this book: https://www.amazon.com/gp/product/B07Q84TQ91/

This looks neat. Am I understanding it correctly that it's written in pseudocode?

(I also went through and love this book). It isn't really even written in any code. It has some pseudocode to describe some things, but it primarily describes tests to write. It's a really excellent book to kick the tires of a new language you want to try out.
