This book provides a fundamental understanding of global illumination algorithms. It discusses a broad class of algorithms for realistic image synthesis and introduces a theoretical basis for the algorithms presented. Topics include: physics of light transport, Monte Carlo methods, general strategies for solving the rendering equation, stochastic path-tracing algorithms such as ray tracing and light tracing, stochastic radiosity including photon density estimation and hierarchical Monte Carlo radiosity, hybrid algorithms, metropolis light transport, irradiance caching, photon mapping and instant radiosity, beyond the rendering equation, image display and human perception. If you want to design and implement a global illumination rendering system or need to use and modify an existing system for your specific purpose, this book will give you the tools and the understanding to do so.
The goal of image synthesis is to create, using the computer, a visual experience that is identical to what a viewer would experience when viewing a real environment. Radiosity and Realistic Image Synthesis offers the first comprehensive look at the radiosity method for image synthesis and the tools required to approach this elusive goal. Basic concepts and mathematical fundamentals underlying image synthesis and radiosity algorithms are covered thoroughly. (A basic knowledge of undergraduate calculus is assumed). The algorithms that have been developed to implement the radiosity method ranging from environment subdivision to final display are discussed. Successes and difficulties in implementing and using these algorithms are highlighted. Extensions to the basic radiosity method to include glossy surfaces, fog or smoke, and realistic light sources are also described. There are 16 pages of full colour images and over 100 illustrations to explain the development and show the results of the radiosity method. Results of applications of this new technology from a variety of fields are also included. Michael Cohen has worked in the area of realistic image synthesis since 1983 and was instrumental in the development of the radiosity method. He is currently an assistant professor of computer science at Princeton University. John Wallace is a software engineer at 3D/EYE, Inc., where he is the project leader for the development of Hewlett-Packard's ATRCore radiosity and ray tracing library. A chapter on the basic concepts of image synthesis is contributed by Patrick Hanrahan. He has worked on the topic of image synthesis at Pixar, where he was instrumental in the development of the Renderman software. He has also led research on the hierarchical methods at Princeton University, where he is an associate professor of computer science. All three authors have written numerous articles on radiosity that have appeared in the SIGGAPH proceedings and elsewhere. They have also taught the SIGGRAPH course on radiosity for 5 years. - The first comprehensive book written about radiosity - Features applications from the fields of computer graphics, architecture, industrial design, and related computer aided design technologies - Offers over 100 illustrations and 16 pages of full-color images demonstrating the results of radiosity methods - Contains a chapter authored by Pat Hanrahan on the basic concepts of image synthesis and a foreword by Donald Greenberg

Photorealistic rendering strives to generate images from computer modeled scenes with an image quality as close to real life as possible. A major issue in rendering is simulation of local and global light reflection in a scene. Both ray tracing and radiosity algorithms capture only some of the possible light reflection phenomena. Recently developed two-pass algorithms combine the ray tracing and radiosity approaches and are able to capture the whole range of light reflection. This book is a collection of papers discussing the latest developments, including a new range of improvements, in stochastic sampling strategies, radiosity form factor calculation, and parallel processing for ray tracing and radiosity. A number of papers on rendering applications in interior design, lighting design, and remote sensing conclude the volume. The contributions are revised versions of papers originally presented at the Second Eurographics Workshop on Rendering, held in Barcelona, Spain, in May 1991. The book fully reflects the state of the art in rendering and presentsa wide variety of novel techniques. It will interest researchers and students in computer graphics, as well as designers who want to apply rendering techniques for realistic simulation in lighting design, interior design, and architecture.
Once the exclusive domain of a handful of academic researchers working with high-powered graphics workstations, now you can use radiosity to create extremely realistic, true-color images using off-the-shelf personal computers. Radiosity offers the ability to accurately render diffuse reflections, color bleeding between surfaces, realistic shadows, and detailed shading within shadows. More than this, it can create photorealistic images that are impossible to achieve using conventional ray tracing techniques. This book offers you a unique opportunity to explore this technology in depth.
Some of the best current research on realistic rendering is included in this volume. It emphasizes the current "hot topics” in this field: image based rendering, and efficient local and global-illumination calculations. In the first of these areas, there are several contributions on real-world model acquisition and display, on using image-based techniques for illumination and on efficient ways to parameterize and compress images or light fields, as well as on clever uses of texture and compositing hardware to achieve image warping and 3D surface textures. In global and local illumination, there are contributions on extending the techniques beyond diffuse reflections, to include specular and more general angle dependent reflection functions, on efficiently representing and approximating these reflection functions, on representing light sources and on approximating visibility and shadows. Finally, there are two contributions on how to use knowledge about human perception to concentrate the work of accurate rendering only where it will be noticed, and a survey of computer graphics techniques used in the production of a feature length computer-animated film with full 3D characters.
