      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.
    • Contribution to Methodic in CAD 

      Duhovnik, J. (The Eurographics Association, 1983)
      In the paper the design process is analysed and a new model of the design process which is usefull in CAD is explained. At working a construction with the computer we have to consider the function and form. The function ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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, ...
