    • SAMMIE-3-D GRAPHICS FOR HUMAN FACTORS APPLICATIONS 

      Kingsley, Eliot C. (The Eurographics Association, 1982)
      In the last five years there has become available a wide range of computer aided three dimensional modelling systems, but only one of these has been specifically developed for evaluating human factors aspects of designs, ...

    • THE EFFECTIVENESS OF HIGH-LEVEL GRAPHICAL LANGUAGES IN DEALING WITH VARIOUS GRAPHICAL DOMAINS 

      Ross, R.; Schrack, G. (The Eurographics Association, 1982)
      There are many domains in which graphical programming languages can be applied. Use of a particular graphical programing language will be limited if the domains in which it can be applied are restricted. High-level graphical ...

    • A FAST ALGORITHM FOR COLOUR REGION SEGMENTATION 

      Stark, J.P.W.; Mahdavieh, Y.; Tjahjardi, T. (The Eurographics Association, 1982)
      An algorithm is described which analyses colour scenes in terms of regions. These regions are defined to have the same 'colour'. In this context the colour of a region is determined by its position in the CIE chromaticity ...

    • GKS in C 

      Rosenthal, David S. H.; Hagen, Paul fen (The Eurographics Association, 1982)
      A binding of GKS, the draft ISO standard for 2D graphics software, to the programming language C is presented, together with the principles underlying its design. The binding is compared with the binding to FORTRAN. An ...

    • THE REPRESENTATION AND USE OF MULTIVARIATE INFORMATION IN GRAPHIC FORM 

      Kirby, G. H.; Visvalingam, M. (The Eurographics Association, 1982)

    • INTERACTIVE GENERATION OF 3-DIMENSIONAL COMPUTER GRAPHICS 

      Sutty, George J. (The Eurographics Association, 1982)
      A new technology employing a vibrating mirror produces spacefilling images. An observer views a reflection of a CRT in a moving mirror. By displaying a proper sequence of pictures 30 times a second, a space filling ...

    • A PACKAGE FOR PROCESSING REMOTE SENSING DATA INTERACTIVELY ON A MINI-COMPUTER SYSTEM 

      C.M.C.Jones,; J.P.W.Stark,; F.T.Howell, (The Eurographics Association, 1982)
      A package for the analysis of time sequence remote sensing data is described, which has been designed to run interactively on a mini-computer system utilising colour graphics facilities. The core of the system performs a ...

    • A METHODOLOGY FOR POPULATING DEFAULT COLOR MAPS 

      Straayer, David H. (The Eurographics Association, 1982)
      A standard for using colors in computer graphics systems is proposed. A key aspect of this proposed standard is to allow two different levels of access to colors. At the first level, colors are selected from a standard ...

    • A PRACTICAL STRATEGY FOR CERTIFYING GKS IMPLEMENTATIONS 

      Brodlie, K. W.; Maguire, M. C.; Pfaff, G. E. (The Eurographics Association, 1982)
      The question of how to validate GKS implementations is crucial to the success of GKS as an international standard for computer graphics. This problem has been addressed by a series of certification workshops sponsored by ...

    • A COMPUTER GRAPHICS PACKAGE FOR TEACHING CRYSTAL MORPHOLOGY 

      Angell, Ian O.; Moore, Moreton (The Eurographics Association, 1982)

    • GRAPHIC DISPLAYS IN THE COMPUTER AIDED DESIGN OF LIFT SYSTEMS 

      Barney, G.C. (The Eurographics Association, 1982)
      The sizing of lift systems to meet passenger demands is normally carried out in a quantitative way by calculation. Nothing is done to determine the quality of service provided. This paper describes how a computer aided ...

    • ATTRIBUTE HANDLING IN GKS 

      Sutcliffe, D C (The Eurographics Association, 1982)
      Following an intensive international review, GKS was adopted by ISO as a Draft Proposal in October 1981, GKS, Graphical Kernal System, is a 2-D device independent graphics system. One of the features, which distinguishes ...

    • MEASURES OF OPERATOR S VISUAL ACCOMMODATION AND CONVERGENCE TO INFORMATION DISPLAYS 

      Murch, Gerald M. (The Eurographics Association, 1982)
      Measurements of a display user s lens accommodation and binocular convergence were used to assess the visual impact of display color, display technology, display work time, and display contrast. The studies reported here ...

    • INTERACTIVE GRAPHICS IN THE ANALYSIS OF PUBLIC UTILITY NETWORKS 

      Stimson, K.R.; Efthymiadis, A.E.; Brameller, A.; Allan, R.N. (The Eurographics Association, 1982)
      This paper describes a suite of programs which have been developed in close collaboration with the appropriate public utilities; electricity supply, water and gas industries. The techniques are based on interactive computing ...

    • CHITRA - A LOW COST 2-D GRAPHICS PACKAGE FOR THE DESIGN OF DISCRETE SYSTEMS 

      Kumar, Ashok; Visweswara, G. H.; Rajaram, S.; Prabhakar, A. (The Eurographics Association, 1982)
      A general purpose 2-D graphics package termed CHITRA has been developed, to aid the design of discrete systems. CHITRA permits the rapid interactive description and design of multiterminal subsystems and links for their ...

    • THE IMPORTANCE OF A CORRECT APPROACH TO THE DESIGN OF METAFILES STANDARDS
