The fully commented (but not entirely clean) code is here: http://www.gabrielgambetta.com/tiny_raytracer_full.js

Also, I'm halfway through writing a Computer Graphics textbook, half of it dedicated to raytracing.

I'd buy it, please post the link once its done, or if you want any proof readers or people to type in the code to check for typos I'd be happy to help.
