      F.I.R.S.T. (Fast Interactive Raster scan workSTation) is designed as a low cost high performance display for interactive applications. Low cost is achieved by using dynamic memories, and high performance implies a high ...

    • GENERATION OF COMPLEX 3D FINITE ELEMENT MESHES ON TURNKEY GRAPHIC SYSTEMS 

      Altimimi, K. (The Eurographics Association, 1980)
      This paper outlines a new approach to finite element mesh generation that has been developed at Perkins Engines on a Computervision CADDS III system. Unlike other finite element mesh generation packages, PEPFEM - G (Perkins ...

    • OPTIMIZED SOFTWARE DISTRIBUTION IN SATELLITE GRAPHICS SYSTEMS 

      Cullmann, Norbert (The Eurographics Association, 1980)
      Interactive computer graphics requires satellite systems. The two software techniques used today with these systems ('fixed-function' and 'programmable satellite') showed to be unsatisfactory. This paper points out refined ...

    • CONSIDERATIONS ON EXTENSIONS OF INPUT FUNCTIONS BASED ON A GRAPHICAL KERNEL SYSTEM 

      Hillebrand, K.; Weiss, J. (The Eurographics Association, 1980)
      The German DIN-Proposal for Graphic Systems provides five classes of input types and three different methods of reading them. In this paper considerations are made on providing a much more powerful interface for the ...

    • C. G .A. L. 

      Comninos, Peter; Webster, Graeme (The Eurographics Association, 1980)
      C.G.A.L. stands for Computer Graphics and Animation Language, and as its name implies, it is a computer language especially designed to help the user produce still and animated pictures with a Digital Computer. The major ...

    • COMPUTER GRAPHICS AND ARCHITECTURE 

      Rogers, Gary (The Eurographics Association, 1980)
      Because computer-generated architectural drawings derive from common data bases, they can be more useful than those drawn manually. Beyond viewing functions, other operations (such as financial, spatial, and thermal analyses) ...

    • KISS - AN EXPERIMENT IN THE DESIGN OF IMAGE SYNTHESIS SYSTEMS 

      GRAVE, M. (The Eurographics Association, 1980)
      During the last years, raster graphics have become more and more important, and there is a need in developing a new generation of graphic systems. In this paper a first experiment designed as a "raster extension" to an ...

    • THE GHOST-80 INTERACTIVE METAFILE 

      Prior, W.A.J.; Sutherland, R.J. (The Eurographics Association, 1980)
      In an interactive graphics environment, a random-access metafile has advantages over the usual serial type. A description is given of the use of such an interactive metafile in the GHOST-80 graphics system, together with ...

    • SURFACE FITTING BY MEANS OF SPLINES 

      Brunet, P. (The Eurographics Association, 1980)
      Algoritms related with surface interpolation use either global interpolants or local methods. When dealing with irregularly distributed data points, the former are usually cumbersome whereas the later may present continuity ...

    • GEOGRAPHIC INFORMATION SYSTEMS AND THE ODYSSEY PROJECT 

      Teicholz, E.; Nisen, B. (The Eurographics Association, 1980)
      There are numerous public and private agencies that are currently creating geographic (location specific) data. These agencies include the Census Bureau (County DIME, Urban Atlas, DIME files), the United States Geological ...

    • COMPUTER GRAPHICS APPLIED TO HUMAN MOTION ANALYSIS AND BODY FORCE EVALUATION 

      Iwata, Kazuaki; Moriwaki, Toshimichi; Kawano, Tsuneo (The Eurographics Association, 1980)
      The human body motions during standing up and sitting down from/to a chair are analyzed employing a minicomputer system equipped with a graphic tablet and CRT displays. A two-dimensional mathematical model of the human ...

    • THE DESIGN OF A GENERAL-PURPOSE COMMAND INTERPRETER FOR GRAPHICAL MAN-MACHINE COMMUNICATION TO BE BUILT ON TOP OF A GKS 

      Borufka, H.G.; Pfaff, G. (The Eurographics Association, 1980)
      A 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 ...
