In his well presented and very well researched book, Henrik Wann Jensen demonstrates the technique of photon mapping I found the book to be well written and thorough The primary audience for this book will be computer graphics researchers in either industry or academia interested in creating highly realistic images, and computer graphics students at the graduate or advanced undergraduate level. The introduction and background chapters are particularly well written, making this a useful text for a graduate-level course in image synthesis. -Bruce Gooch, SIAM Review, August 2002

The creation of realistic three-dimensional images is central to computer graphics. Photon mapping, an extension of ray tracing, makes it possible to efficiently simulate global illumination in complex scenes. Photon mapping can simulate caustics (focused light, such as shimmering waves at the bottom of a swimming pool), diffuse inter-reflections (for example, the bleeding of coloured light from a red wall onto a white floor, giving the floor a reddish tint), and participating media (such as clouds or smoke). This book provides a guide to photon mapping, offering both the theory and the practical insight necessary to implement photon mapping and simulate all types of direct and indirect illumination efficiently.
