Physically based rendering : from theory to implementation

Even as developments in photorealistic computer graphics continue to affect our work and leisure activities, practitioners and researchers are devoting more and more attention to non-photorealistic (NPR) techniques for generating images that appear to have been created by hand. These efforts benefit every field in which illustrationsthanks to their ability to clarify, emphasize, and convey very precise meaningsoffer advantages over photographs. These fields include medicine, architecture, entertainment, education, geography, publishing, and visualization. Non-Photorealistic Computer Graphics is the first and only resource to examine non-photorealistic efforts in depth, providing detailed accounts of the major algorithms, as well as the background information and implementation advice readers need to make headway with these increasingly important techniques. Already, an estimated 10% of computer graphics users require some form of non-photorealism. Strothotte and Schlechtweg's important new book is designed and destined to be the standard NPR reference for this large, diverse, and growing group of professionals. \*Hard-to-find information needed by a wide range and growing number of computer graphics programmers and applications users. \*Traces NPR principles and techniques back to their origins in human vision and perception. \*Focuses on areas that stand to benefit most from advances in NPR, including medical and architectural illustration, cartography, and data visualization. \*Presents algorithms for two and three-dimensional effects, using pseudo-code where needed to clarify complex steps. \*Helps readers attain pen-and-ink, pencil-sketch, and painterly effects, in addition to other styles. \*Explores specific challenges for NPRincluding "wrong" marks, deformation, natural media, artistic technique, lighting, and dimensionality. \*Includes a series of programming projects in which readers can apply the book's concepts and algorithms.;Pixel manipulation of images -- Lines, curves, and strokes -- Simulating natural media and artistic techniques -- Stroke-based illustrations -- Working with 2.5D data structures -- Geometric models and their exploitation in NPR -- Lighting models for NPR -- Distorting non-realistic renditions -- Applications for NPR -- A conceptual framework for NPR.

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."

• The book that won its authors a 2014 Academy Award for Scientific and Technical Achievement from the Academy of Motion Picture Arts and Sciences
• New sections on subsurface scattering, Metropolis light transport, precomputed light transport, multispectral rendering, and much more
• Includes a companion site complete with source code for the rendering system described in the book, with support for Windows, OS X, and Linux: visit www.pbrt.org
• Code and text are tightly woven together through a unique indexing feature that lists each function, variable, and method on the page that they are first described
