Physically Based Rendering, Third Edition: From Theory to Implementation

__Physically Based Rendering: From Theory to Implementation, Third Edition__, describes both the mathematical theory behind a modern photorealistic rendering system and its practical implementation. Through a method known as 'literate programming', the authors combine 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, users will learn to design and employ a fully-featured rendering system for creating stunning imagery. This completely updated and revised edition includes new coverage on ray-tracing hair and curves primitives, numerical precision issues with ray tracing, LBVHs, realistic camera models, the measurement equation, and much more. It is a must-have, full color resource on physically-based rendering. * Presents up-to-date revisions of the seminal reference on rendering, including new sections on bidirectional path tracing, numerical robustness issues in ray tracing, realistic camera models, and subsurface scattering * Provides the source code for a complete rendering system allowing readers to get up and running fast * Includes a unique indexing feature, literate programming, that lists the locations of each function, variable, and method on the page where they are first described * Serves as an essential resource on physically-based rendering ""Computer graphics, and rendering in particular, is full of beautiful theory. The theory covers physical concepts, such as light fields and the interaction of light with different materials, and mathematical concepts, such as integral equations and Monte Carlo integration. The great thing about computers is that they allow us to build rendering systems based on the best 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 i Matt Pharr, Wenzel Jakob, Greg Humphreys.
