Chapter 10. Photon Mapping in a Nutshell

Photon mapping has been around for some time now and is proving to be better at computing global illumination than radiosity. This chapter explains photon mapping from a theoretical point of view. Later chapters will then delve deeper into explaining its practical applications. The book will, in essence, implement the method in the following chapters. This chapter is an overview of what photon mapping is and why it's far better than radiosity and ray tracing. So let's begin.
