This book is an extensive treatise on the most up-to-date advances in computer graphics technology and its applications. Both in business and industrial areas as well as in research and development, you will see in this book an incredible devel opment of new methods and tools for computer graphics. They play essential roles in enhancing the productivity and quality of human work through computer graph ics and applications. Extensive coverage of the diverse world of computer graphics is the privilege of this book, which is the Proceedings of InterGraphics '83. This was a truly interna tional computer graphics conference and exhibit, held in Tokyo, April 11-14, 1983, sponsored by the World Computer Grpphics Association (WCGA) and organized by the Japan Management Association (JMA) in coopera'tion' with *~CM-SIGGRAPH. InterGraphics has over 15 thousands participants. This book consists of seven Chapters. The first two chapters are on the basics of computer graphics, and the remaining five chapters are dedicated to typical appli cation areas of computer graphics. Chapter 1 contains four papers on "graphics techniques". Techniques to generate jag free images, to simulate digital logic, to display free surfaces and to interact with 3 dimensional (3D) shaded graphics are presented. Chapter 2 covers "graphics standards and 3D models" in five papers. Two papers discuss the CORE standard and the GKS standard. Three papers de scribe various 3D models and their evaluations.

This book seeks to elucidate picture engineering as a new discipline for hand- ling the entire scope of picture processing in a systematic manner. Picture engineering as a discipline has three aspects, the first of which is methodo- logical, technical, and architectural. The second consists of pattern ana- lysis and recognition of pictorial input, picture database management, inclu- ding picture data structure and data representation for picture storage and transformation, and computer graphics for picture output and display. Ver- satile applications such as computer-aided design, manufacturing and testing (CAD/CAM/CAT), office automation (GA), robotics, and fancy computer arts com- prise the third aspect. This book covers all three aspects in original papers by leading experts in the discipline. The book is divided into six parts. Part I covers the central topic of pictorial database management in three papers. The first, by Yamaguchi and Kunii, presents a data model for designing a picture database computer. The second, by Klinger, discusses the organization of computers for handling pic- torial data. In the third paper, Shi-Kuo Chang treats the indexing and enco- ding of pictorial data. Part II is devoted to picture representation. First, a general approach to picture analysis using both syntactic (structural) and semantic information is described by Fu. This is followed by an in-depth explanation of various 3-D shape representation methods by Ikebe and Miyamoto. Schumaker elaborates polar spline representation of 3-D objects, and finally,Enomoto, Yonezaki and Watanabe describe a unique method of characterizing 3-D surfaces by struc- ture lines.

Computer graphics as a whole is an area making very fast progress and it is not easy for anyone, including experts, to keep abreast of the frontiers of its various basic and application fields. By issuing over 100 thousand calls for papers through various journals and magazines as weil as by inviting reputed specialists, and by selecting high quality papers which present the state of the art in computer graphics out of many papers thus received, this book "Frontiers in Computer Graphics" has been compiled to present the substance of progress in this field. This volume serves also as the final version of the Proceedings of Computer Graphics Tokyo '84, Tokyo, Japan, April 24-27, 1984 which, as a whole, attracted 16 thousand participants from all over the world; about two thousand to the conference and the remaining 14 thousand to the exhibition. This book covers the following eight major frontiers of computer graphics in 29 papers: 1. geometry modelling, 2. graphie languages, 3. visualization techniques, 4. human factors, 5. interactive graphics design, 6. CAD/CAM, 7. graphie displays and peripherals, and 8. graphics standardization. Geometry modelling is most essential in displaying any objects in computer graphics. It determines the basic capabilities of computer graphics systems such as whether the surface and the inside of the object can be displayed and also how efficiently graphical processing can be done in terms of processing time and memory space.
