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
