    • CSI: A Processor for Image Synthesis 

      Charot, Francois; Rousee, Frank (The Eurographics Association, 1986)
      A high performance processor convenient for image synthesis is presented. The processor named CSI is programmable and can support either image synthesis by polygons or by ray casting. CSI consists of two 32- bits floating ...
    • A Multiple Application Graphics Integrated Circuit - MAGIC 

      Agate, M.; Finch, H.R.; Garel, A.A.; Grimsdale, R.L.; Simmonds, A.C.; Lister, P. F. (The Eurographics Association, 1986)
      MAGIC is a geometry processor which Corms a part of a graphics system based on parallel processing. The number of MAGIC processors required is dictated by the desired system performance. Each unit is capable of controlling ...
    • Towards a Formal Specification of the GKS Output Primitives 

      Duce, D. A.; Fielding, E. V. C. (The Eurographics Association, 1986)
    • The Integrated Display Controller (IDC) for VLSI-Design Workstations 

      Strk, Jrgen (The Eurographics Association, 1986)
      A display controller to accelerate the updating of the frame buffer in raster displays is presented. The advantage of a frame buffer system is the ability to display pictures of any complexity, flicker free. The disadvantage ...
    • A Multiprocessor Architecture For High-Quality Interactive Displays 

      Sutherland, Robert J. (The Eurographics Association, 1986)
      A multiprocessor array coupled to a deep framebuffer is proposed as the basis for an interactive user environment of high quality. Several aspects of such an architecture are considered, improvements on previous approaches ...
    • Geometric Boundary Modelling without Topological Data Structures 

      Takala, Tapio (The Eurographics Association, 1986)
      The Boundary Representation (BR) scheme for solid modelling is reconsidered and generalized in the paper. It is pointed out that the topological data, though usually represented separately, is derivable from the geometric ...
    • A Pixel-Parallelhidden Surface Algorithm For Constructive Solid Geometry 

      Jansen, Frederik W. (The Eurographics Association, 1986)
      VLSI techniques have greatly enlarged the possibilities to design new frame buffer architectures with parallel processing capabilities down to the pixel level. For these pixel processor systems a parallel hidden surface ...
    • An Advanced Display System With Natural Interactivity 

      Kankaanp, Arto (The Eurographics Association, 1986)
      This paper describes an experimental display system that allows easy interaction with the graphics display. The user uses a pen-like device to draw directly on the display surface. The system is based on an electroluminescent ...
    • A Statistical Method For Adaptive Stochastic Sampling 

      Purgathofer, Werner (The Eurographics Association, 1986)
      Stochastic sampling is a good alternative to pure oversampling in terms of image quality. A method for adaptively controlling the number of required samples to the complexity of the picture is presented. The quality of the ...
    • Multi-Dimensional Graphics: Algorithms & Applications 

      Inselberg, Alfred (The Eurographics Association, 1986)
    • A Visualisation Tool for (Landscape) Architects 

      Lankhorst, Mrs. J. Roos - Klein (The Eurographics Association, 1986)
      In a small and crowded country such as the Netherlands both the government and the individual people are very concerned with what is happening in their environment. Apart from the ecological impacts, the visual effects of ...
    • Towards the Construction of Graphical Interfaces on the Basis of Geometric Models 

      Prospero, Manuel Joao; Messina, Luiz Ary (The Eurographics Association, 1986)
      Dialogue control and dialogue object structures are the outlined concepts developed in this paper. Phases of a CAD-Process are presented to show an outstanding application for the concepts The use of logic programming ...
    • An Adaptive Graphics Interface for Effective Visual Representation 

      Holynski, Marek; Garneau, Robert; Lewis, Elaine (The Eurographics Association, 1986)
