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.
