    Leray, P; Burnod, Y (The Eurographics Association, 1993)
    We describe here simulation elements and results of a new kind of 3D Vision Machine. for pre-processing in 3D Object & movement analysis using the biological concept of the Cortical Column Paradigm in the primary visual ...

  • A Difference Engine for Image Reconstruction 

    Blake, EH; Kuijk, AAM (The Eurographics Association, 1993)
    A diffetence engine is described that is designed to be used as low level component of a raster graphicsarchitecture. The speed of the system (11 ns per operation) is achieved by the use of custom VLSI componentsfor the ...

  • An Architecture for Ray - Bezier Patch Intersection 

    Vijt, P De; Claesen, L; Man, H De (The Eurographics Association, 1993)
    A new fast ray - patch intersection algorithm is presented. The algorithm correctly handles all ray - patch intersections. A number of parametersare derived from a numerical analysis of the algorithm and the datapad is re ...

  • Designing a half toning coprocessor 

    Kugler, A; Hersch, R D (The Eurographics Association, 1993)
    Halftoning is a fairly slow process when executedby software on conventional processors. To speed uphalf toning, a half toning algorithm has been developed andintegrated into a dedicated hardware architecture. Thispaper ...

  • Hemispherical Projection for Progressive Radiosity Calculation on Massively Parallel Architectures 

    Renaud, C; Bricout, F; Lepretre, E (The Eurographics Association, 1993)
    This paper describes a massively parallel implementation of the progressive radiosityalgorithm. Our algorithm is based on an hemispherical projection approach, which provides an accurate from factor approximation. As the ...

  • A Parallel Accelerator for Generating Virtual Studio Sets 

    Sahiner, A V; Lefloch, P; Nimmo, A; Paker, Y (The Eurographics Association, 1993)
    Recent developments in digital video techniques and the use of computers in video andtelevision production provide new opportunities for programmes. Key technologies which embrace these developments are advanced computer ...

  • The Role of Power Dissipation and Locality of Reference in the Specification of High Performance Graphics Algorithms 

    Smit, J.; Bentum, M.; Samsom, M. (The Eurographics Association, 1993)
    The amount of power dissipated by the implementation of an algorithm, for instance in the form of a dedicatedchip-set, is considered to be one of the most important constraints for the selection of a high performance ...

  • Direct Visualization of Quadrics 

    Laporte, H; Nyiri, E; Froumentin, M; Chaillou, C (The Eurographics Association, 1993)
    Today, most of the powerful graphic systems are based on 3D-triangle display methods.However, this approach generates well-known problems, like the low quality ofcontours and shading, and the necessity to have large amounts ...

  • Parallel Fixed Point Digital Differential Analyzer 

    Molla, RP; Quiros, R; Lluch, J; Vivo, R (The Eurographics Association, 1993)
    Two main serial algorithms to scan convert straight lines have beenproposed: Bresenham and Digital Differential AnalyzeLThe Bresenham algorithm has became a standard because of integer arithmetic. Many theoretical solutions ...

  • VHDL Based Design of Graphics ASICs 

    White, M; Dunnett, G; Lister, P F; Grimsdale, R (The Eurographics Association, 1993)
    The design of graphics ASICs for geometry and rasterisation processing has traditionally involved the use of schematic design entry where by functional blocks are netlisted and instantiatedon the schematic. This methodology ...

  • A VLSI Design for Fast Vector Normalization 

    Knittel, G. (The Eurographics Association, 1993)
    The design of a vector normalizer is described. It is an integral part of our graphics subsystemfor scientific visualization, but will be of great use for speeding up any computer graphics architecture.In the actual design, ...
