Physically Based Rendering, Second Edition describes both the mathematical theory behind a modern photorealistic rendering system as well as its practical implementation. A method known as 'literate programming' combines human-readable documentation and source code into a single reference that is specifically designed to aid comprehension. The result is a stunning achievement in graphics education. Through the ideas and software in this book, you will learn to design and employ a full-featured rendering system for creating stunning imagery.
This new edition greatly refines its best-selling predecessor by streamlining all obsolete code as well as adding sections on parallel rendering and system design; animating transformations; multispectral rendering; realistic lens systems; blue noise and adaptive sampling patterns and reconstruction; measured BRDFs; and instant global illumination, as well as subsurface and multiple-scattering integrators. These updates reflect the current state-of-the-art technology, and along with the lucid pairing of text and code, ensure the book's leading position as a reference text for those working with images, whether it is for film, video, photography, digital design, visualization, or gaming.
The author team of Matt Pharr, Greg Humphreys, and Pat Hanrahan garnered a 2014 Academy Award for Scientific and Technical Achievement from the Academy of Motion Picture Arts and Sciences based on the knowlege shared in this book.The Academy called the book a 'widely adopted practical roadmap for most physically based shading and lighting systems used in film production.'

Matt Pharr is works as an engineer for Neoptica, a San Francisco start-up, where he works on interactive graphics. Previously, he was a member of the technical staff at NVIDIA and was a co-founder of Exluna, where he developed off-line rendering software and investigated applications of graphics hardware to high-quality rendering. He holds a BS degree from Yale University and a PhD from the Stanford Graphics Laboratory under the supervision of Pat Hanrahan, where he researched both theoretical and systems issues related to rendering and has written a series of SIGGRAPH papers on these topics.

Chapter One Introduction
Rendering is the process of producing a 2D image from a description of a 3D scene. Obviously, this is a very broad task, and there are many ways to approach it. Physically based techniques attempt to simulate reality; that is, they use principles of physics to model the interaction of light and matter. In physically based rendering, realism is usually the primary goal. This approach is in contrast to interactive rendering, which sacrifices realism for high performance and low latency, or nonphotorealistic rendering, which strives for artistic freedom and expressiveness.
This book describes pbrt, a physically based rendering system based on the ray-tracing algorithm. Most computer graphics books present algorithms and theory, sometimes combined with snippets of code. In contrast, this book couples…
