    • A PAINT PROGRAM FOR THE GRAPHIC ARTS IN PRINTING 

      Willis, P J (The Eurographics Association, 84)
      There is considerable scope for the application of computer techniques to help the graphic designer working with printed products, provided that pictures of high technical quality result. Described here is the product of ...

    • APPLICATION OF COMPUTER-GENERATED ANIMATION IN EUROPEAN SPACE RESEARCH 

      Kristiansen, E. (The Eurographics Association, 84)
      In space research, there is often a need to illustrate motion, such as a spacecraft's orbital motion and attitude manoeuvres. This paper presents various types of applications for computer generated animation in space ...

    • THE DEVELOPMENT OF COMPUTER GRAPHICS CURRICULA FOR DESIGN EDUCATION 

      King, Robin G. (The Eurographics Association, 1984)
      With the imminent availability of low cost, high resolution computer graphics systems suitable for visual and graphic arts applications, design education must now come to terms with radical changes in design methodology ...

    • Three-Dimensional Data Input by Selection of Hierarchically Defined Blocks 

      Yamaguchi, K.; Inamoto, N.; Kunii, H. S.; Kunii, T. L. (The Eurographics Association, 1984)
      This paper discusses inputing three dimensional solid object data by means of a two dimensional tablet. This method involves refining an object by gradually generalizing a class of 'permissible' objects. The design of an ...

    • GRAPHICAL SUPPORT IN A USER INTERFACE MANAGEMENT SYSTEM 

      Guest, Steve; Edmonds, Ernest (The Eurographics Association, 1984)
      SYNICS2 is a User Interface Management System (UIMS) using the concept of Recursive Transition Networks (RTN) for its control structure. It is used as an intelligence terminal would be, being situated between the computer ...

    • DIRECT CADD DRAWING (A Flexible Screen Oriented user interface to CADD) 

      Hudson, Fred W.; Jr., (The Eurographics Association, 1984)
      Computer aided design/drafting (CADD) system developers are taking advantage of the latest developments in personal computing and human factors research by including icon (picture) driven, direct manipulation menus in a ...

    • COMPUTER GRAPHICS DEVELOPMENT IN EUROPE 

      Marechal, Guy; Matthys, Jan (The Eurographics Association, 1984)
      Europe is becoming aware that a political determination to collaborate is required, if it wants to attain the position it could claim on the basis of its research achievements. This is especially true in the field of ...

    • SHAPING THE FUTURE A SYSTEMS APPROACH TO MIS PLANNING 

      Kirkley, John L. (The Eurographics Association, 1984)

    • COMPUTER-AIDED THREE-DIMENSIONAL RECONSTRUCTION FROM SERIAL SECTIONS: A SOFTWARE PACKAGE FOR RECONSTRUCTION AND SELECTIVE IMAGE GENERATION FOR COMPLEX TOPOLOGIES 

      Huijsmans, D. P.; Lamers, W. H.; Los, J. A.; Smith, J.; Strackee, J. (The Eurographics Association, 1984)
      To extend computer-aided three-dimensional reconstruction of (microscopic) biological structures to complex topologies, a number of specially developed contour algorithms are employed to generate hidden-line displays of ...

    • CADASTRAL MAPPING PILOT PROJECT 

      Sondergaard, Aage (The Eurographics Association, 1984)
      The immense and complicated task of converting a traditional cadastral map production into the most modern computer assisted interactive graphic production technique, and at the same time achieve increased productivity, ...

    • THE DESIGN OF A USER INTERFACE FOR A CAM APPLICATION 

      Sauter, Roland (The Eurographics Association, 1984)
      This paper describes a user interface which has been designed for the rough environment of a workshop floor. It has a strictly hierarchical structure of the commands, but allows a lot of context-free operator's actions and ...

    • SUDS - SUrface Description System 

      Moretonl, Henry P.; Bergeron, R. Daniel (The Eurographics Association, 1984)
      A library of routines has been developed for the design of arbitrarily curved three-dimensional surfaces. The routines provide for the description and editing of surfaces. Surfaces are defined by families of parametric ...

    • RAY TRACING OBJECTS DEFINED BY SWEEPING A SPHERE 

      Wijk, J.J. van (The Eurographics Association, 1984)
      The basic calculation underlying ray tracing is that of the intersection of a line with the surfaces of an object. A method is presented here for performing this calculation for a new and powerful class of objects, those ...

    • INTERACTIVE EDITING OF POLYGONS 

      Olsson, Lennart (The Eurographics Association, 1984)
      This paper describes an internal data structure which can be used in interactive editing of polygons. A user can delete, restore, split and merge polygons and change type and direction of polygons. The polygons that are ...

    • AN APPROACH TO THE DESIGN OF HARDWARE CURVE GENERATORS FOR GRAPHIC DISPLAYS 

      Alia, G.; Martinelli, E.; Tani, N. (The Eurographics Association, 1984)
      Special devices to generate curves are more and more convenient because of ever growing performance graphic tools are requested for. In this paper an approach to the design of fast hardware curve generators is proposed, ...

    • AN ANALYTICAL VISIBILITY METHOD FOR DISPLAYING PARAMETRICALLY DEFINED SURFACES 

      Rehwald, Peter; Hornung, Christoph (The Eurographics Association, 1984)
      This paper describes an analytical method to determine the visible parts of a Cartesian product surface. The bounds of these visible areas are determined in terms of the (u,v)-parameter-plane. This leads to many advantages ...
