    • AVLSI Chip for Ray Tracing Bicubic Patches 

      Pulleyblank, R W.; Kapenga, J. (The Eurographics Association, 1986)
      A VLSI chip for ray tracing bicubic patches in Bezier form is explored. The purpose of the chip is to calculate the intersection point of a ray with the bicubic patch to a specified level of accuracy, returning the location ...
    • Developments in High Performance CGI Systems 

      Grimsdale, R L.; Lister, P. F. (The Eurographics Association, 1986)
      This contribution describes some work being undertaken in the design andimplementation of architectures for high performance Computer Image Generationfor a range of applications from workstations to flight simulator visual ...
    • CSG Hidden Surface Algorithms for VLSI Hardware Systems 

      Jansen, Frederik W. (The Eurographics Association, 1986)
      Constructive Solid Geometry (CSG) is a solid modeling representation thatdefines objects ·as Boolean combinations of primitive solids. For thedisplay of such objects, both the visibility problem and the problem ofcombining ...
    • A Survey of Simulator Requirements 

      Joseph, H. (The Eurographics Association, 1986)
      Simulators have been developed to train pilots, sailors or car drivers withoutthe costs and risks of moving their real vehicles. To obtain high success intraining, the simulators have to provide a high level of realism. ...
    • A Visual System for a Traffic Simulator 

      Möller, R. (The Eurographics Association, 1986)
      The prototype of a modular CGI-system for real time simulation in atraffic simulator will be presented. It will be shown, that withthe proposed configuration of a large asymmetric multiprocessorsystem, organized in different ...
    • Looking at Workstation Architectures from the Viewpoint of Interaction 

      Krömker, Detlef (The Eurographics Association, 1986)
      Today's design of sophisticated graphics workstations may be characterized by the terms 3D-system, user driven, object-oriented user interfaceand multiple-windows system with the challenge to create high levelinterfaces ...
    • Towards a Z-Buffer and Ray-Tracing Multimode System based on Parallel Architecture and VLSI chips 

      P.Lemy, (The Eurographics Association, 1986)
      After the hidden surfaces algorithms for 3D rastergraphics, hardware design isthe main problem, for many applicat ions, such as : Audiovisual animat ions. CADCAM,and simulation.After a short description of our CUBI 7 system ...
    • Towards a 3-D Graphics Workstation 

      Kaufmann, Arie (The Eurographics Association, 1986)
      A voxel-map based architecture which lays the foundations for a 3-D graphics workstation,called the CUBE Workstation, is presented. The architecture is centered around a largecubic frame-buffer of voxels, operated on by ...
    • Utilization of VLSI for Creating an Active Data Base of 3-D Geometric Models 

      Skyttä, J.; Takala, T. (The Eurographics Association, 1986)
      Parallelism of geometric computation can be achieved by distributing the computation efforts according to essentially three different strategies, based on functional, spatial and structural division, respectively (Mantyla ...
    • Display Architecture for VLSI -based Graphics Workstations 

      Hagen, P. J. W. ten; Kujik, A. A.M.; Trienekens, C. G. (The Eurographics Association, 1986)
      At present, two popular development areas in computer graphics are improvement ofinteraction behaviour and more realistic graphics.The architecture for a high quality interactive workstation proposed in this work isdesigned ...
    • "Position Paper:Display Hardware for Boolean Expression Models" 

      Thomas, A. L. (The Eurographics Association, 1986)
      In any discussion of graphics hardware there appear to be two basic positions which can be adopted. The first is that of the technologist, who is primarily concerned with what it is possible to make and how to make it. The ...
