Overview

In Ray Tracing In One Weekend and Ray Tracing: the Next Week, you built a “real” ray tracer.

In this volume, I assume you will be pursuing a career related to ray tracing and we will dive into the math of creating a very serious ray tracer. When you are done you should be ready to start messing with the many serious commercial ray tracers underlying the movie and product design industries. There are many many things I do not cover in this short volume; I dive into only one of many ways to write a Monte Carlo rendering program. I don’t do shadow rays (instead I make rays more likely to go toward lights), bidirectional methods, Metropolis methods, or photon mapping. What I do is speak in the language of the field that studies those methods. I think of this book as a deep exposure that can be your first of many, and it will equip you with some of the concepts, math, and terms you will need to study the others.

As before, www.in1weekend.com will have further readings and references.
