This book is the first issue of a EUROGRAPHICS publication series in the field of computer graphics, an important field of research and a versatile tool for various application areas. The availability of powerful hardware at an affordable price and the evolution of high standard software have led to a rapidly increas- ing expansion of computer graphics and the penetration of compu- ter graphics techniques and systems into a wide range of applica- tion areas. This book series will cover state-of-the-art surveys as well as scientific contributions on specific areas of research and develop- ment. The first book in the series contains the Tutorial Notes of the EUROGRAPHICS '83 conference, held in Zagreb, Yugoslavia, in September 1983. It covers four major aspects of computer graphics today: - The first part contains a detailed introduction into computer graphics, its concepts, its methods, its tools, and its devices. It gives an easy access for the newcomer to the field and it offers an overview of the state of the art in computer graphics. - The second part is devoted to interactive techniques. This is currently one of the most important fields of research in computer graphics. Important aspects of this research and its current state are reported. From the developments described here, in the near future powerful generally applicable user interface management systems are likely to evolve.
