Rendering is a crucial component of computer graphics― the conversion of a description of a 3D scene into an image for display. Algorithms for animation, geometric modeling, and texturing all must feed their results through some sort of rendering process for the results to be visible in an image. Focusing on realistic images, physically based rendering incorporates ideas from a range of disciplines, including physics, biology, psychology, cognitive science, and mathematics. This book presents the algorithms of modern photorealistic rendering and follows step by step the creation of a complete rendering system. As each new rendering concept is introduced it is also shown implemented in code―there is no better way to understand the subtle and complex process of rendering. The code itself is highly readable, written in the literate programming style that mixes text describing the system with the code that implements it. The result is a stunning achievement in graphics education for students, professionals, and researchers.
*CD-ROM with the source code for a complete rendering system for Windows, OS X, & Linux―with many examples of images created by the system throughout the 4 color text
*The code and text are tightly woven together through the technique of literate programming with a unique indexing feature that lists all locations of functions, variables, and methods on the page they are first described
*The most complete guide to understanding, designing, and building a rendering system

Review
"I think this book is great. It's state-of-the-art, and covers the area from soup to nuts and with more depth than any other book I know." ―Eric Haines, Autodesk Inc.
From the Back Cover
"Computer graphics, and rendering in particular, is full of beautiful theory…. This book turns the theory of image-making into a practical method for creating images." —from the foreword by Pat Hanrahan, Canon USA Professor, Stanford University
From movies to video games, computer-rendered images are pervasive today. Physically Based Rendering introduces the concepts and theory of photorealistic rendering hand in hand with the source code for a sophisticated renderer. By coupling the discussion of rendering algorithms with their implementations, Matt Pharr and Greg Humphreys are able to reveal many of the details and subtleties of these algorithms. But this book goes further; it also describes the design strategies involved with building real systems—there is much more to writing a good renderer than stringing together a set of fast algorithms. The rendering system described in this book is itself highly readable, written in a style called literate programming that mixes text describing the system with the code that implements it. Literate programming gives a gentle introduction to working with programs of this size. This lucid pairing of text and code offers the most complete and in-depth book available for understanding, designing, and building physically realistic rendering systems.

Simply superb
By Mike Ramsey
I've been working on a parallel renderer in my spare time for a bit and without a doubt - this book is a definate keeper in my library. A solid introduction, as well as providing more intermediate material- this book also provides a ray tracing system that is immediately extensible for your own experiments.
This book has enough material and ideas to keep a ray tracing programmer busy for years.

indispensible
By Manchor Ko
I do ray tracing and GI for a living. When I got started on my ray tracer I was struggling with several basic issues. Even though I tried to locate all the published material on those subject there was still significant gaps. Issues like 'how to shot photons', what about all these 'cosines'. How do you actually implement a kd-tree. I read Shirley's, Jansen's, Glassner's and Advanced Global Illumination and a lot of the older Siggraph papers. PBRT came out just in time to rescue me. It contains the only complete implementation of a photonmap.
It's strong point is a complete running GI engine. However the literate programming style used in the book meant a lot of time I cannot read a subject by itself. The use of abstract interfaces sort of force you to use the class browser to follow the logic. You pretty much have to read it from the beginning. The quality of the code contained goes beyond the usual standard of code published as examples. It contains a rather sophiscated random number generator. Its treatment of LDS plus sampling and recontruction in general is excellent. It is the only source that shows how to implement Li's algorithm to generate random rays to sample a sphere. Same goes for Malley's. Shirley and Chui's concentric sampling method is hidden in the appendix of a old Siggraph paper.
The book also has code to sample and model most of the common light sources. Which is surprisingly non-trivial.
I highly recommend this book but it does require a certain level of commitment to get the most out of this book. The chapters on sampling, ray differential, texture filtering, light transport I consider must reads for all graphics programmer even though you might not be working on ray tracing.

Six stars out of five
By MrZ
Although it is not possible here, I am fairly sure this book deserves such rating. This is truly remarkable work and is likely to become a classic text in the field of computer graphics.
It is not a survey-type book, instead of trying to describe every possible method out there, the authors have concentrated on a few selected techniques, that are not only good (modern, fast, easy to implement, etc.), but also have some pedagogical merits and can serve as a gentle introduction to the world of ray tracing and digital image synthesis. Despite focusing on selected areas, the authors managed to squeeze here in an amazing amount of material. Among other topics, this book covers: subdivision surfaces, ray-primitive intersection acceleration techniques (3D DDA and kd-tree), color and radiometry, anti-aliasing, tone mapping, physically based reflection models, texture mapping (including texture anti-aliasing using ray differentials), area lights and HDR Image Based Lighting, volume scattering and much more.
A large part of the book has been devoted to the light transport and Monte Carlo techniques. One can find there an introduction to the theory of Monte Carlo estimation (including selected methods for reducing variance and computation time, like Russian roulette, multiple importance sampling or stratified sampling) and explanation of important light transport equations (rendering and transfer equations).
Finally the authors have described (and implemented) several solutions for the rendering equation: Whitted-style recursive ray tracing, direct illumination estimation, path tracing, irradiance caching and photon mapping.
However, it is not only the vastness of the material covered in this book, that causes this volume should be praised so highly. Perhaps, the style, in which this book has been written, is even more impressive. For each of the topics, the authors start with what is usually known as "dry math and theory", and then show how it is supposed to work as an algorithm (including its dirty details) and finally they explain how to turn this algorithm into C++ code. Each of those transitions concentrates on a small portion of the problem, so it is still easy to understand. Anyone, who had to turn a SIGGRAPH paper into something that works, will immediately recognize what kind of gem this book is - it actually shows how to do it!
This brilliant blend of theory and practice is one of its brightest spots, for learning the theory and math formulas is one thing, but writing a working, robust implementation is completely another.
Those, who prefer studying sources, will get source code of a very good, physically based, extensible ray tracer (called pbrt) with the best documentation one could ever imagine. Documentation that gives the rationale for almost every line of code. It shows not only how they did it, but also why they did it that way.
It is not the only book, that one will ever need - computer graphics is a vast topic - too big to be covered in a single volume, even as huge as this one. However, it is certainly one of the books that everyone interested in photorealistic rendering should buy. The price of this book is really low, if you think about it as of an excellent, first-rate computer graphics course.
Aimed at students, researchers and people interested in computer graphics algorithms, it is an indispensable book for anyone willing to write his own photorealistic (not necessarily physically based!) ray tracer and learn more about computer image synthesis.
