    • A Multi-Processor Workstationwith a Logic-Enhanced Distributed Frame Buffer 

      Jansen, Frederik W. (The Eurographics Association, 1987)
      A graphics workstation should offer both a wide variety of 20 and 3D realtime display functions as well as a programmable parallel-processing capacity for large processing tasks. A system concept is proposed that meets ...
    • A Multiple Application Graphics Integrated CircuitMAGIC II 

      Finch, H.R; Agate, M.; Garel, A.A.; Lister, P.F.; Grimsdale, RL (The Eurographics Association, 1987)
      This paper describes the design considerations for a polygon graphics geometry processor subsystem. The architecture for a Multiple Application Graphics Integrated Circuit (MAGIC II) is outlined, and low, medium and high ...
    • New Algorithms for Computer Graphics 

      Ovennars, Mark H. (The Eurographics Association, 1987)
      "IntroductionThe area of computational geometry deals with the study of algorithms for problems concerning geometric objects like e.g. lines, polygons, circles, etc. in the plane and in higher dimensional space. Since its ...
    • An O(log N) Parallel Time Exact Hidden-LineAlgorithm 

      Dévai, F. (The Eurographics Association, 1987)
      "Parallel algorithms are given for the exact solution of the hidden-line problem. Most of the parallel algorithms proposed for visibility problems in the literature give approximate solutions. and thus cannot yield an upper ...
    • Parallel Subpixel Scanconversion 

      Claussen, Ute (The Eurographics Association, 1987)
      "IntroductionComputer graphics and its subsections image processing, image analysis and image generation are known to be a wide field for the application of parallel architectures. While in image processing and analysis ...
    • Partially Ordered Search Indices in the Organizationof a Fixed Hierarchy 

      Skyttä, Jorma; Takala, Tapio (The Eurographics Association, 1987)
      "IntroductionThe mapping of even very advanced algorithms directly to hardware does not typically bring good results as these algorithms are originally designed for sequential processing. However, the power of the modern ...
    • Pixel-Planes 4: A Summary 

      Eyles, John; Austint, John; Fuchs, Henry; Greer, Trey; Poulton, John (The Eurographics Association, 1987)
      We describe the current state of the Pixel-planes research project, whose goal is to develop powerful raster graphics systems for the next generation of workstations, The first full-scale prototype has been in regular use ...
    • Ray Tracing Rational B-Spline Patches in VLSI 

      Schneider, Bengt-Olaf (The Eurographics Association, 1987)
      Rational B-spline surfaces make it possible to merge the concepts of freeform surfaces and that of surfaces described by rational polynomials especially conic sections. For ray tracing it is crucial to determine the ...
    • Reconstructing Solids from Tomographic Scans --The PARCUM II System-· 

      Jackèl, D. (The Eurographics Association, 1987)
      The computer-aided design of mechanical parts is supported by sophisticated geometric modelers and visualized by high-performance raster graphics systems allowing for a realistic display. The geometric modeler accepts the ...
    • A Two-Dimensional Frame Buffer Processor 

      Kaufman, Arie (The Eurographics Association, 1987)
      The two-dimensional Frame Buffer Processor (FBP) is part of a proposed raster graphics computer architecture. It is a hardware-oriented organisation of a variation of a bitblt engine with a much richer repertoire. In ...
    • A Vector-like Architecture for Raster Graphics 

      Akman, Varol; Hagen, Paul ten; Kuijk, Fons (The Eurographics Association, 1987)
      Raster graphics, while good at achieving realistic and cost-effective image generation, lacks useful (e.g. high-level) and fast (e.g. almost real-time) interaction facilities. One may try to speed up the entire classical ...
    • VLSI Drawing Processor Utilizing Multiple ParallelScan-Line Processors 

      Denault, Damian; Ryherd, Eric; Torborg, John (The Eurographics Association, 1987)
      In a typical graphics system, a single drawing processor is used to perform pixel level drawing operations, one pixel at a time. A VLSI based drawing processor and image memory controller is presented which takes advantage ...
