    We describe a software package for the automation of design activities and the automatic production of design documentation. The package is currently beeing used by a consulting organisation in the design of railway -highway ...
  • Decision Support Systems - The Significance of Hybrid Communication Facilities for Operations Research Consultancy 

    Gels, Martin (The Eurographics Association, 1983)
    In this paper the significance of suitable combinations of analogue and digital communication facilities in the design and implementation of Decision Support Systems (DSS) will be discussed within the context of practical ...
  • 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 ...
  • Visualizing Inversions in Time with Computer Graphics 

    Mezzina, Maria (The Eurographics Association, 1983)
    An example of how computer graphics have been used to visually explore the INVERSION SPACE, and its educational and artistic implications.
  • XGKS - A Multitask Implementation of GKS 

    Herman, I.; T.Tolnay-Knefely,; Vincze, A. (The Eurographics Association, 1983)
    A multitask design for GKS is presented, a realization aiming small computers and intelligent graphic hardware.
  • Computer Graphic Presentation of Road Data 

    Koren, Hans; Holbaek-Hanssen, Erik; Tjugen, Olav H.; Wiborg, Trond (The Eurographics Association, 1983)
    This paper presents a system for plotting traffic accidents and other data related to roads, on computer drawn maps. A method for simultaneous presentation of many different aspects of the road is also described.
  • 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 ...
  • Fast Previewing Techniques in Raster Graphics 

    Jansen, F.W.; Wijk, J.J. van (The Eurographics Association, 1983)
    The long processing times inherent in the use of raster graphics techniques for the shading of complex scenes, complicate the design and debugging of a picture. The efficiency of the picture-generating process can, however, ...
  • Towards GKS Binding to PASCAL 

    Antoy, Sergio; Dettori, Giuliana (The Eurographics Association, 1983)
    When binding GKS to the Pascal programming language some problems arise which are not trivial, Problems related to the use of a library, to the passing of array parameters to procedures and to the definition of suitable ...
