This looks like a slimmed down version of the book Realistic Ray Tracing writen by the same author Peter Shirley. The book is still very short ~200 pages and develops a raytracer.
He has also written one of my favorite general introductions to computer graphics if your looking for a usable survey text that has most of the basic formulas.
