  • Cellular Architectures and Algorithmsfor Image Synthesis 

    Meriaux, Michel (The Eurographics Association, 1987)
    The aim of this paper is to provide some refiexions and partial results about cellular architectures for image synthesis and graphics. As some steps of image synthesis involve a long processing time, quite incompatible ...

  • 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 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 Multiple Application Graphics Integrated CircuitMAGIC II

    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 ...

  • Comparison of Two Floatin~Point Arithmetic Unitsfor a Precomputer in a Graphics System forReal Time Simulation 

    Möller, Reinhard (The Eurographics Association, 1987)
    This paper compares two realized concepts of floating point units in a visual system for a traffic simulator. The hardware structure of a Transformation Processor is described, with which a set of 1x4 vectors can be floating ...

  • 3D Graphics For Consumer Applications -How Realistic Does it Have to Be? 

    Winser, Paul (The Eurographics Association, 1987)
    The design of graphics Ie's for the consumer market has performance limitations imposed by the need to maintain low cost, and must be driven by consideration of the potential applications. The likely requirements for a ...

  • 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 ...

  • 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 ...

  • 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 ...
