    • INTERACTIVE COMPUTER GRAPHICS IN COMPUTER-AIDED DECISION ANALYSIS 

      Carpano, Marie-Jose; Leduc-Leballeur, Andre (The Eurographics Association, 1980)
      Two systems for computer-aided decision analysis are presented. In both of them the man-machine communication is achieved through graphical displays. The first one has been designed to facilitate interactive structural ...
    • A CAD - SYSTEM FOR INTERACTIVE GRAPHICAL HANDLING OF HIERARCHICAL BLOCK DIAGRAM INFORMATION 

      Leinemann, Klaus (The Eurographics Association, 1980)
      The CAD - system named GRIMBI is designed to support the functional modelling of large engineering systems. GRIMBI includes a data definition facility, to define model classes functionally and graphically. The data ...
    • 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 ...
    • 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 ...
    • 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 ...
    • IMAGE MODELING ASPECTS OF NON-PROCEDURAL PARALLEL PROCESSING LANGUAGE
