Physically Based Rendering

Más información sobre el libro

Rendering is essential in computer graphics, transforming 3D scene descriptions into display images. Animation, geometric modeling, and texturing all rely on rendering to visualize their results. Focusing on realistic imagery, physically based rendering draws from various fields such as physics, biology, psychology, cognitive science, and mathematics. This book details modern photorealistic rendering algorithms and guides readers through the development of a complete rendering system. Each new concept is accompanied by code implementation, offering an effective way to grasp the intricate rendering process. The code is presented in a literate programming style, blending descriptive text with the corresponding code for clarity. This approach enhances the educational experience for students, professionals, and researchers alike. Included is a CD-ROM featuring the complete rendering system's source code for Windows, OS X, and Linux, along with numerous image examples generated by the system. The text and code are interlinked using literate programming techniques, complete with a unique indexing feature that highlights all functions, variables, and methods upon their first mention. This resource serves as a comprehensive guide to understanding, designing, and building a rendering system.
