    • A 33MHz 16. Bit Gradient Calculator for Real-Time Volume Imaging 

      Margala, Martin; Durdle, Nelson G.; Raso, V. James; Hill, Doug L. (The Eurographics Association, 1994)
      This paper describes a gradient calculator which forms an important part of a shading processor being developed for a high resolution high performance real-time general purpose volume imaging system. The proposed architecture ...

    • Display Memory Access Issues and Anti-Aliasing with a Virtual Reality Graphics Controller. 

      Regan, Matthew; Pose, Ronald (The Eurographics Association, 1994)
      An address recalculation pipeline used in conjunction with image composition enables the profitable technique of prioritized rendering to be employed in virtual reality applications. These techniques however require the ...

    • Experience with a Difference Engine for Graphics 

      Kuijk, A.A.M.; Blake, E.H.; Steffens, E.H. (The Eurographics Association, 1994)
      "The prototype of a novel raster graphics architecture has now become operational. The display hardware can be regarded as a very fast difference engine that works in two-dimensions. The speed is partly achieved by the use ...

    • A hardware architecture for video rate smooth shading of Volume data 

      Doggett, Michael C.; Hellestrand, Graham R. (The Eurographics Association, 1994)
      This paper describes a new architecture for generat ing smoothly shaded two dimensional images of volume data. This architecture fits into an image synthesis pipeline and uses only simple arithmetic operations and a look-up ...

    • IMAGINE - The IMAGe engINE 

      Den, Sjef ten (The Eurographics Association, 1994)
      The tremendous computing power needed for the inter active processing and generation of visual information is more and more becoming a major technology driver in the consumer market. Illustrative are the bench marks used ...

    • Integration of Live Video and Computer Graphics for Video Effect Generation 

      Osterfeld, Utz; Ackermann, Hans-Josef (The Eurographics Association, 1994)
      We present the architecture of a system, based on a PC, covering real-time video processing by integration of live video and computer graphics. The video processing and integration are realized by generation and evaluation ...

    • Interactive Rendering of Volumetric Data Sets 

      Juskiw, "Scott; Durdle, Nelson G. (The Eurographics Association, 1994)
      The bela architecture for interactive rendering of regularly structured volumetric data sets is presented. The proposed architecture is scalable and uses custom processors to achieve high-speed shading, projection. and ...

    • The Multimedia Video Processor (MVP) 

      Short, Graham (The Eurographics Association, 1994)
      In 1987 engineers from Texas Instruments started work on the specification of a device which would become the next generation in its TMS320 Digital Signal Processor and TMS340 Graphics System Processor families, building ...

    • A Parallel Implementation of Bidirectional Ray Tracing on Transputer-based System 

      Kawai, Toshiyuki; Kami, M.; Teranishi, Tadamasa; Abeki, Jun-ichi; Ohnishi, Hironobu (The Eurographics Association, 1994)
      This paper describes a parallel processing scheme for bidirectional ray tracing which improves the reality of the image drastically. It is organized from two stages, i.e. light ray tracing and viewing ray tracing. In light ...

    • A Real Time Rendering System with Normal Vector Shading 

      Jackél, D.; Rüsseler, H. (The Eurographics Association, 1994)
      This paper presents a graphics workstation for real time display of Phong shaded polygons. The applied shading method is based on normal vector interpolation using a precalculated reflectance map. Nearly 40 million pixels ...

    • A Scalable Architecture for Volume Rendering 

      Knittel, Günter (The Eurographics Association, 1994)
      We describe the operational principles of a scalable hardware accelerator for volume rendering. The basic philosophy is to provide an atomic unit which already provides sophisticated volume graphics at interactive rendering ...

    • Sheared Interpolation and Gradient Estimation for Real-Time Volume Rendering 

      Pfister, Hanspeter; Wessels, Frank; Kaufman, Arie (The Eurographics Association, 1994)
      In this paper we present a technique for the interactive control and display of static and dynamic 3D datasets. We describe novel ways of tri-linear interpolation and gradient estimation for a real-time volume rendering ...
