    • 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) ...

    • 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 ...

    • COMPUTER GRAPHICS IN MULTIPLE MICROPROCESSOR SYSTEM 

      Ae, Tadashi; Takahashi, Koichi; Chiba, Haruyoshi; Ito, Tsurumi (The Eurographics Association, 1980)
      In this paper we propose a method to implement the moving patterns which are consecutively related in a small computer system. Suppose that the patterns are constructed of many block elements. A pattern is derived by the ...

    • 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 ...

    • 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 ...

    • DRAW - A GRAPHICAL PROGRAM WITH THE ABILITY TO DRAW CHEMICAL FORMULAE 

      Bicknell, Keith (The Eurographics Association, 1980)
      DRAW is a program that allows the user to produce diagrams on the incremental plotter or other graphical display devices by means of simple instructions. Particular requirements for chemical formulae have been catered for, ...

    • Easy to Use Graph Drawing Procedures in ALGOL 68 

      Butland, S. D.; Butland, J. (The Eurographics Association, 1980)
      An ALGOL68 implementation of a comprehensive set of graph drawing procedures is described. The procedures are designed to enable scientists and engineers writing programs in ALGOL68 to produce a wide range of graphs with ...

    • F.I.R.S.T., A HIGH RESOLUTION RASTER SCAN DISPLAY SYSTEM FOR INTERACTIVE LAYOUT OF TEXT AND FIGURES 

      Röthlisberger, H.; Rakotomalala, J. (The Eurographics Association, 1980)
      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 ...

    • FAST COLOUR RASTER GRAPHICS USING AN ARRAY PROCESSOR 

      Walsby, Anthony M. (The Eurographics Association, 1980)
      This paper shows how an array processor technique can be used as the basis of an animated (fast) colour raster display. It is amenable to expansion for more colours, greater speed and resolution, and large scale integration ...

    • 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 ...
