物理渲染:从理论到现实(第3版)Physically Based Rendering FROM THEORY TO IMPLEMENTATION 全彩 非影印版 正版电子书 From movies to video games, computer-rendered images are pervasive today. Physically Based Rendering introduces the concepts and theory of photorealistic rendering hand in hand with the source code for a sophisticated renderer. By coupling the discussion of rendering algorithms with their implementations, Matt Pharr and Greg Humphreys are able to reveal many of the details and subtleties of these algorithms. But this book goes furthe r; it also describes the design strategies involved with building real systems—there is much more to writing a good renderer than stringing together a set of fast algorithms. For example, techniques for high-quality antialiasing must be considered from the start, as they have implications throughout the system. The rendering system described in this book is itself highly readable, written in a style called literate programming that mixes text describing the system with the code that implements it. Literate programming gives a gentle introduction to working with programs of this size. This lucid pairing of text and code offers the most complete and in-depth book available for understanding, designing, and building physically realistic rendering systems. r; it also describes the design strategies involved with building real systems—there is much more to writing a good renderer than stringing together a set of fast algorithms.
