The book covers computer graphics programming on the basis of the Graphical Kernal System, GKS. GKS is the first international standard for the functions of a computer graphics system. It offers capabilities for creation and representation of two-dimensional pictures, handling input from graphical workstations, structuring and manipulating pictures, and for storing and retrieving them. It represents a methodological framework for the concepts of computer graphics and establishes a common understanding for computer graphics systems, methods and applications. This book gives an overview over the GKS concepts, the history of GKS design and the various system interfaces. A significant part of the book is devoted to a detailed description of the application of GKS functions both in Pascal and a FORTRAN-Language environment.
