    • MARTI-A Multiprocessor Architecture for Ray Tracing Images 

      Hebert, M-P.; McNeill, M. D. J.; Shah, B.; Grimsdale, R. 1.; Lister, P. F. (The Eurographics Association, 1990)
      Multiprocessor systems are well suited to ray tracing, since each ray can be traced independently. However, the large databases required to model complex scenes create problems of data access. In this paper we propose a ...

    • A Multipurpose Hardware Shader 

      Pöpsel, Josef; Tikwinski, Eckard (The Eurographics Association, 1990)
      For the last few years the state of the art in producing three-dimensional Gouraud shaded graphics has been the use of Gouraud shading hardware. Combined with z-buffering it enables graphic workstations to provide real ...

    • A New Space Partitioning for Mapping Computations of the Radiosity Method onto a Highly Pipelined Parallel Architecture 

      Shen, Li-Sheng; Deprettere, E.; Dewilde, P. (The Eurographics Association, 1990)
      Despite the fact that realistic images can be generated by ray-tracing and radiosity shading, these techniques are impractical for scenes of high complexity because of the extremely high time cost. Several attempts have ...

    • Real Time Phong Shading 

      Claussen, Ute (The Eurographics Association, 1990)
      Nowadays, hardware support for Gouraud shading is state-of-the-art. Most hardware implementations of the Phong shading algorithm lack flexibility, for example are restricted in the number of light sources. In this paper, ...

    • Some Practical Aspects of Rendering 

      Schilling, Andreas (The Eurographics Association, 1990)
      "The scan conversion of simple primitives, e.g., vectors and triangles has been worked on in many different ways. General descriptions of algorithms often do not consider 'minor' problems, that can be difficult to solve ...

    • The Triangle Shading Engine 

      Ackermann, Hans-Josef; Hornung, Christoph (The Eurographics Association, 1990)
      This paper describes an algorithm implementing the Gouraud-shading of triangles and its realization in hardware. Different realizations using span shading hard­ ware are discussed. Their drawbacks lead to the concept of a ...
