    • Parallel Processing on a Transputer-based Graphics Board 

      Pereira, Joijo; Reis, Francisco; Vinagre, Carlos; Gomes, Mario R. (The Eurographics Association, 1988)
      Th.s paper discusses the design of a graphics board with parallel architecture based on Transputers and a resolution of 1024 x 1024 x 8 [VIN88], namely: Ihe processing unit (il plays the role of a display processor), the ...
    • "A Display Controller for an Object-levelFrame Store System" 

      Jayasinghe, JAK.S.; Kuijk, A.A.M.; Spaanenburg, L. (The Eurographics Association, 1988)
      In [3] and [1] a new architecture for a Computer Image Generating (CIG) system designed to have optimal interaction support for realistic 3D graphics has been presented. There it was stated that from an interaction paint ...
    • A VLSI Design Strategy for Graphics 

      Nimmo, AD.; Lister, P.F.; Grimsdale, R.L. (The Eurographics Association, 1988)
      The tools available for ASIC design now offer the features and functionality necessary to permit ideas to be realised in silicon In a relatively short period of lime, This paper introduces work undertaken at Sussex University ...
    • A Distributed Data Model for Raytracing 

      Skyttä, Jorma; Takala, Tapio (The Eurographics Association, 1988)
      Ray tracing is a superior method for producing realistic images. It can take into account all natural phenomena covered by classical ray optics in image formation, and that without any extra modeling effort. The main ...
    • Combining Z-buffer Engines for Higher-Speed Rendering 

      Molnar, Steven (The Eurographics Association, 1988)
      Described IS a hardware architecture for combining the outputs of a number of z-buffer rendering engines to achieve higher performance than is possible with a single renderer. It allows a combination of renderers to achieve ...
    • A Massively Parallel Approach for the Design of a Raytracing Oriented Architecture 

      Muntean, T.; Waille, Ph. (The Eurographics Association, 1988)
      Solving time critical problems requires a computing power of an order of magnitude greater than todays available conventional computers. The use of massively parallel architectures appears to be an attractive and effective ...
    • A VLSI Architecture for Image Composition 

      Shaw, Christopher D.; Green, Mark; Schaeffer, Jonathan (The Eurographics Association, 1988)
      This paper describes a new parallel architecture for performing high-speed raster graphics. A central host broadcasts graphical objects to a number of identical graphics processors. Each graphics processor produces a raster ...
    • An Integrated Highly Parallel Architecture for Image Reconstruction 

      Lattard, Didier; Mazare, Guy (The Eurographics Association, 1988)
      The large amount of information and computations is a critical problem in image processing. In this paper we show a highly oarallel method to do image reconstruction which performs at real-time, using an asynchronous ...
    • Content-Addressable Memories for Quadtree-8ased Images 

      Oldfield, J.V.; Williams, R.D.; Wiseman, N.E.; Brûlé, M.R. (The Eurographics Association, 1988)
      Quadtrees are attractive for storing and processing mages with area coherence, but performance has been limited by software overheads. A Content-Addressable Memory (CAM) with ternary storage allows single-cycle searches ...
    • Hardware Support for the Display and Manipulation of Binary Voxel Models 

      Jense, G.J.; Huijsmans, D.P. (The Eurographics Association, 1988)
      We describe some of our experiences with the implementation of a 3D reconstruction system for the visualization of the shapes and structural development of biological objects. We use a binary voxel model as volumetric ...
    • The voxblt Engine: A Voxel Frame Buffer Processor 

      Kaufman, Arie (The Eurographics Association, 1988)
      The voxblt Engine (vE) is a 3D frame-buffer processor which manipulates and processes ''3~ bitmaps"" (voxel maps) stored in a cubic frame buffer of voxels. The vE is the 3D counterpart of the 20 frame buffer processor, ...
    • PROOF: An Architecture for Rendering In Object Space 

      Schneider, Bengt-Olaf; Claussen, Ute (The Eurographics Association, 1988)
      This paper gives a short introduction into the field of computer image generation in hardware. It discusses the two main approaches, namely partitioning in Image space and In object space. Based on the object space ...
    • Point-driven Generation of Images from a Hierarchical Data Structure 

      Jong, Dirk de; Siobbe, Paul van; Splunter, Marinus van (The Eurographics Association, 1988)
      In this paper, a system IS described which renders an image from a hierarchical data structure in a point-driven way. The data structure allows dynamic color mapping and arbitrary affine transformat·ons of objects with ...
