  • Bramer, B; Sutcliffe, D C (The Eurographics Association, 1981)
    Raster scan displays are now available at lower costs than vector refresh displays. While many offer more facilities such as fill area and colour or greyscale capabilities, few offer a display file facility. It is desirable ...
  • Rase, Wolf D. (The Eurographics Association, 1981)
    To satisfy the cartographic requirements for spatial analysis, planning and forecast on the federal level in West Germany the Federal Research Institute for Regional Geography and Regional Planning established a system for ...
  • Webster, C. A. G. (The Eurographics Association, 1981)
    The CAPITOL system aims to provide a flexible but low cost 3-D modelling and visualization system which can be used as an integral part of the creative aesthetic and visual design process by interior designers and architects. ...
  • Jimenez, Javier; Navalon, Jose L. (The Eurographics Association, 1981)
    We present methods to vectorize automatically information given in raster form, the algorithms used are discussed briefly, and results for some test cases are presented. The compression of information is discussed as well ...
  • Eloranta, Kirsi (The Eurographics Association, 1981)
    The purpose of this paper is to describe the results of our recent land information systems research in The Institute of Geodesy at Helsinki University of Technology. Our goal is to make research on municipal systems by ...
  • Newman, Hannah (The Eurographics Association, 1981)
    Videotex is a system by which information can be accessed from central data bases by the general public. By the use of a television receiver augmented by a micro-computer controlled interface device, a user can access pages ...
  • Reed, Theodore N. (The Eurographics Association, 1981)
    The Common Graphics System (CGS) was developed at the Los Alamos National Laboratory. A standard device driver interface was defined for graphics device drivers and for use by user-callable graphics subroutine packages. ...
  • J.R.Gallop, (The Eurographics Association, 1981)
    Starlink is a network of powerful interactive minicomputers, for use by astronomers in the UK; these computers run common software distributed from a central node. The use of standard general purpose graphics software in ...
  • Gnettner, Wolfgang (The Eurographics Association, 1981)
    Voice recognition is discussed as a useful tool in interactive graphics. Two applications in electronical design and surveying are described. First results show an increased input speed, a low error probability and more ...
  • Bigelmaier, Anton; Brunner, Helmut; Strack, Helmut (The Eurographics Association, 1981)
  • Trispel, S.; Günther, K. (The Eurographics Association, 1981)
    Users of technical systems become increasingly involved in computer controlled dialogues of various forms. One kind of dialogue is of the interrogative form based on the exchange of alphanumeric and symbolic strings via ...
  • Mäntylä, Martti; Takala, Tapio (The Eurographics Association, 1981)
    The Geometric workbench (GWB), an experimental. geometric modeling system, is described. It is based on a hybrid representation scheme, where solids are represented by CSG volume trees and boundary representations. Boundary ...
  • Cunha, J.D. (The Eurographics Association, 1981)
    This paper describes our experience in the development of an application using the SGL system presented in previous publications ( [2] [3] ). Special attention is paid to the pos sibilities and limitations due to GKS ...
  • Hartwig, R. R. (The Eurographics Association, 1981)
    This is a method to be applied in R&D. 1. A surface is generated, containing exactly all given points z(x,y). 2. The degree of accuracy is gradually specified. One can swap 'ACCURACY for SPEED'. 3. 'Out of the picture' ...
  • Magnenat-Thalmann, Nadia; Thalmann, Daniel; Bergeron, Philippe (The Eurographics Association, 1981)
    The MIRALIB library is a powerful graphical library which may be used with MIRA-2D, a graphical PASCAL extension as well as with the standard PASCAL language. MIRALIB includes figure algebra routines, figure measure ...
  • Lindner, R.; Rix, J. (The Eurographics Association, 1981)
    The interface of the Graphical Kernel System GKS is examined with respect to the demands of realtime raster graphics. First the computation time for the different transformations is estimated, to show the great gap between ...
  • W.Barth,; J.Dirnberger,; W.Purgathofer, (The Eurographics Association, 1981)
    A high-level programming language like PASCAL offers data types, variables, constants and operators, by which the programmer can reflect the actual world as a model inside the computer. The world of numbers and text has ...
  • Opheim, Harald (The Eurographics Association, 1981)
    In order to reduce storage and subsequent processing costs for a digitized cartographic curve, we may wish to reduce the data set. The data reduction method which is described in this paper, can be used on-line during the ...
  • Lozover, O.; Preiss, K. (The Eurographics Association, 1981)
    Cubic B-splines are often used to represent curves and are usually specified by a process of interaction on a graphic screen between the designer and the computer. This paper describes a program which, when given a digitized ...
  • Renner, Gabor; Pochop, Vladimir (The Eurographics Association, 1981)
    A new method for interpolation is presented which starts from a given set of data pints. The resulting curve consisting of a set of polynomials has tangent vector continuity in the nodes, and can have straight line sections ...
