Item A VLSI Implementation of the Graphics Standard GKS(Blackwell Publishing Ltd and the Eurographics Association, 1983) Encarnacao, J L; Lindner, R.; Mehl, M.; Pfaff, G.; Strasser, W.The main advantage when using a standardized graphics system is quite obvious: the application programs become portable. Integrating such a system - and GKS (Graphical Kernel System) is the only one being standardized internationally - into VLSI (Very Large Scale Integration) chips, this graphics system may become an integral part of graphical devices. This guarantees a uniform interface of such devices to GKS applications. Devices of many different kinds will become compatible not only with respect to plugging but even in their logical behaviour, eliminating all device dependencies from the host software.We have started to design the GKS-chip which will be able to be used in a great variety of devices (vector and raster type). The GKS-chip will bring the computational power to support real time picture updates, limited only by the maximally attainable output data rate.Item An Algorithmic Interpretation of the GKS TEXT Primitive(Blackwell Publishing Ltd and the Eurographics Association, 1983) Brodlie, K W; Pfaff, G.Item THE DESIGN OF A GENERAL-PURPOSE COMMAND INTERPRETER FOR GRAPHICAL MAN-MACHINE COMMUNICATION TO BE BUILT ON TOP OF A GKS(The Eurographics Association, 1980) Borufka, H.G.; Pfaff, G.; C. E. VandoniA model of a general purpose graphical command interpreter (KI) is presented. It is based on the graphical kernel system (GKS) and provides the user with the most common set of commands for solving graphical problems in a dialogue process. Functions for dialogue leading, echoing, error and help messages, editing, and correcting data support interactive working. GKS is demonstrated to be a most suitable graphical basis system for the requirements of the command interpreter. This paper attends to the problems of man-machine communication. Tasks of an operator (as the user or controller of the system) and of an author (as the definator of the application system) as well as the system support of both of them are considered. To adapt the system to the various requirements, tools for extension are provided.
