High Quality Shading And Lighting For Hardware Accelerated Rendering

This book contains the proceedings of the 11th Eurographics Workshop on Rendering, which took place from the 26th to the 28th of June, 2000, in Brno, Czech Republic. Over the past 10 years, the Workshop has become the premier forum dedicated to research in rendering. Much of the work in rendering now appearing in other conferences and journals builds on ideas originally presented at the Workshop. This year we received a total of 84 submissions. Bachpaper was carefully reviewed by two of the 25 international programme committee members, as weil as external reviewers, selected by the co-chairs from a pool of 121 individuals (The programme committee and external reviewers are listed following the contents pages). In this review process, all submissions and reviews were handled electronically, with the exception of videos submitted with a few of the papers (however, some mpeg movies were also sent electronically). The overall quality of the submissions was exceptionally high. Space and time constraints forced the committee to make some difficult decisions. In the end, 33 papers were accepted, and they appear here. Almost all papers are accompanied by color images, which appear at the end of the book. The papers treat the following varied topics: radiosity, ray tracing, methods for global illumination, visibility, reftectance, filtering, perception, hardware assisted methods, real time rendering, modeling for effi cient rendering and new image representations.

This book contains the proceedings of the 10th Eurographics Workshop on Rendering, which took place from the 21st to the 23rd of June, 1999, in Granada, Spain. Origi nally an outgrowth of the annual Eurographics meeting, the workshop was organized by a dedicated group of researchers who felt there was insufficient opportunity at Eu rographics and Siggraph to exchange ideas specifically on rendering. Over the past 9 years, the workshop has become renown as an international watershed for top quality work in this field, attracting between 50 and 100 attendees each year to share their latest research. This year we received a total of 63 submissions. Each paper was carefully reviewed by two of the 25 international programme committee members, as well as two external reviewers, selected by the co-chairs from a pool of 71 individuals. (The programme committee and external reviewers are listed following the contents pages.) In this new review process, all submissions and reviews were handled electronically, with the ex ception of videos submitted with a few of the papers. This streamlined the review process considerably, while reducing the costs and confusion associated with courier delivery of hundreds of papers.

This book covers real-time shading systems, their design and how they work. Procedural shading, long valued for off-line rendering and production animation is now possible on interactive graphics hardware. These developments are important for areas such as game development, product design, and scientific visualization, among others. The authors include examples of techniques for achieving common effects efficiently in a real-time shading language ranging from full procedural shading on advanced specialized hardware to limited, yet surprisingly flexible shading on unextended OpenGL, to modern PC graphics accelerators.

Important elements of games, movies, and other computer-generated content, shadows are crucial for enhancing realism and providing important visual cues. In recent years, there have been notable improvements in visual quality and speed, making high-quality realistic real-time shadows a reachable goal. Real-Time Shadows is a comprehensive guide to the theory and practice of real-time shadow techniques. It covers a large variety of different effects, including hard, soft, volumetric, and semi-transparent shadows. The book explains the basics as well as many advanced aspects related to the domain of shadow computation. It presents interactive solutions and practical details on shadow computation. The authors compare various algorithms for creating real-time shadows and illustrate how they are used in different situations. They explore the limitations and failure cases, advantages and disadvantages, and suitability of the algorithms in several applications. Source code, videos, tutorials, and more are available on the book’s website www.realtimeshadows.com.

This book is a high-level overview of Sh and its relationship to other realtime shading and Graphics processing unit programming languages. It is a reference manual and language specification and methodically and exhaustively presents details of the various features of Sh.
