    • 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 ...

    • 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 ...

      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, ...

    • A COMPUTER GRAPHIC APPROACH TO LATERAL SKULL CEPHALOSTAT RADIOGRAPH ANALYSIS FOR ORTHODONTIC DIAGNOSIS AND TREATMENT PLANNING 

      Hubbold, R.J.; Eid, A.A. (The Eurographics Association, 1984)
      Interactive computer graphics programs have been developed to permit the clinical application of a new method of analysis of craniofacial discrepancies and its use for diagnosis and testing alternative treatment plans. The ...

    • 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 ...

    • COMPUTER GRAPHICS FOR VISUALIZING SIMULATION RESULTS 

      NAKAMAE, Eihachiro; YAMASHITA, Hideo; NISHITA, Tomoyuki (The Eurographics Association, 1984)
      Computer graphics techniques for visualizing the following simulation results are developed: (1) lighting designs for different type sources such as point sources, linear sources, area sources, and polyhedron sources, (2) ...

    • COMPUTER GRAPHICS PRODUCTION AS A BUSINESS 

      Kaneko, Mitsuru (The Eurographics Association, 1984)

    • THE COMPUTER GRAPHICS SCENE IN THE UNITED STATES 

      Badler, Norman I.; Carlbom, Ingrid (The Eurographics Association, 1984)
      We briefly survey the major thrusts of computer graphics activities, examining trends and topics rather than offering a comprehensive survey of all that is happening. The directions of professional activities, hardware, ...

    • 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 ...

    • CONVENTIONAL ELEMENTS OF ENGINEERING DRAWINGS - FREE FORM CURVES 

      Renner, G. (The Eurographics Association, 1984)
      Technical objects which are typically described by free-form surfaces, usually also contain conventional elements (planes, cylinders, cones). Consequently, methods and systems for defining free-form shapes are advantageously ...

    • 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 ...

    • 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 ...
