      A multitask design for GKS is presented, a realization aiming small computers and intelligent graphic hardware.

    • On Developing a GKS Driver Architecture for Raster Workstations 

      Rix, Joachim (The Eurographics Association, 1983)
      The use of raster graphics devices needs adapting to graphics applications. The first graphics standard, the Graphics Kernel System GKS, defines a logical interface on an application and device independent level. The ...

    • Refinement of the Stress Contour Plots by the Local Interpolations, Extrapolations ans Averaging 

      Draskovic, Z.; Berkovic, M. (The Eurographics Association, 1983)
      The purpose of this paper is an attempt to improve the stress contour plots for the simplest two-dimensional finite elements. The proposed approach is achieved by the use of the simple local interpolations, extrapolations ...

    • Decision Support Systems - The Significance of Hybrid Communication Facilities for Operations Research Consultancy 

      Gels, Martin (The Eurographics Association, 1983)
      In this paper the significance of suitable combinations of analogue and digital communication facilities in the design and implementation of Decision Support Systems (DSS) will be discussed within the context of practical ...

    • The GHOST-80 Colour Raster Extensions 

      Prior, W.A.J.; Sutherland, R.J. (The Eurographics Association, 1983)
      The GHOST Graphical Output System has been developed over a long period. The most recent version, GHOST-80 has been enhanced with routines for colour raster displays. The integration of these routines with the existing ...

    • Standard Graphics as a Geometric Modelling Device 

      Takala, T. (The Eurographics Association, 1983)
      A view is taken on geometric modelling systems as abstract data types. Having this frame of reference, the Device Independent Segment Storage of standard graphics is considered, and found to possess useful capability of ...

    • Contribution to Methodic in CAD 

      Duhovnik, J. (The Eurographics Association, 1983)
      In the paper the design process is analysed and a new model of the design process which is usefull in CAD is explained. At working a construction with the computer we have to consider the function and form. The function ...

    • Depth Sorting by Windowing 

      Gangnet, Michel (The Eurographics Association, 1983)
      In this paper we present the first version of a new algorithm for hidden-surface and hidden-line elimination which applies primarily to the generation of indoor perspective views of simple building models. The algorithm ...

    • A High Level Interface to the Graphical Kernel System - GKS
