    • On Developing a GKS Driver Architecture for Raster Workstations 

      Rix, Joachim (The Eurographics Association, 1983)
      The use of raster graphics devices needs adapting to graphics applications. The first graphics standard, the Graphics Kernel System GKS, defines a logical interface on an application and device independent level. The ...
    • The GHOST-80 Colour Raster Extensions 

      Prior, W.A.J.; Sutherland, R.J. (The Eurographics Association, 1983)
      The GHOST Graphical Output System has been developed over a long period. The most recent version, GHOST-80 has been enhanced with routines for colour raster displays. The integration of these routines with the existing ...
    • Refinement of the Stress Contour Plots by the Local Interpolations, Extrapolations ans Averaging 

      Draskovic, Z.; Berkovic, M. (The Eurographics Association, 1983)
      The purpose of this paper is an attempt to improve the stress contour plots for the simplest two-dimensional finite elements. The proposed approach is achieved by the use of the simple local interpolations, extrapolations ...
    • A Delaunay-Based Method for Surface Approximation 

      Floriani, L.De; Falcidieno, B.; C.Pienovi, (The Eurographics Association, 1983)
      This paper describes a method for constructing a surface representation model from a given set of data points.A Triangulated Irregular. Network has been chosen as data structure, thus representing the surface as a set of ...
    • DisArray: A 16x16 RasterOp Processor 

      Page, Ian (The Eurographics Association, 1983)
      RasterOp is a powerful primitive operation for raster graphics. To improve the execution rate of this operation, a machine with a set of 256 1-bit processors organised as a 16x16 array has been constructed. This machine ...
    • Fast Access to Archival Information Stored on Optical Memory Discs 

      Bittner, H.; Krömker, D.; Lenzer, R.; Olsowski, H.D. (The Eurographics Association, 1983)
      A database processor based on a multi-microprocessor system managing archival data was developed for the use in local area networks. To grant fast and easy access from office workstations to heterogeneous information stored ...
    • An Intelligent Graphics Terminal's Intermediate Database 

      Rudalics, M. (The Eurographics Association, 1983)
      The Intelligent Graphics Terminal's Intermediate Database (INGRID) handles storage, retrieval and manipulation of the description of graphic items in the memory of an Intelligent Graphics Terminal. INGRID combines on one ...
    • Interactive Graphical Planning 

      Jackson, Michael J.; Clark, Tony (The Eurographics Association, 1983)
      Accurate planning is an essential part of efficient project management, but computer-aided techniques have, in the past, not fulfilled their potential in this important field, This paper describes how interactive graphics ...
    • Inverse Perspective Mapping in Scanline Order onto Non-Planar Quadrilaterals 

      Hourcade, J.C.; Nicolas, A. (The Eurographics Association, 1983)
      Mapping textures onto three dimensional objects should resolve two class of problem ; first find a correspondence between the texture and the displayed object, secondly filter the texture according the display grid and the ...
    • Depth Sorting by Windowing 

      Gangnet, Michel (The Eurographics Association, 1983)
      In this paper we present the first version of a new algorithm for hidden-surface and hidden-line elimination which applies primarily to the generation of indoor perspective views of simple building models. The algorithm ...
