    • PRESENTATION OF PRODUCT MODEL DATA -AN INTERFACE BETWEEN GRAPHICS AND CAD- 

      Klement, Kornel (Eurographics Association, 1990)
      The associative visualization of revisable product model data is of great importance for the usefulness and the acceptance of standards in the field of CAD data exchange. The outlines of a separate Presentation module which ...

    • COLOR SHADING IN 2D SYNTHESIS 

      Bourdin, J.J.; Braquelaire, J.P. (Eurographics Association, 1990)
      In interactive 2D synthesis applications, features for filling regions are generally elementary (uniform colouring, filling with a regular pattern.. .). Interactive design of 2D colour shadings raises two major problems: ...

    • ADAPTIVE POLYGONIZATION OF IMPLICIT SURFACES USING SIMPLICIAL DECOMPOSITION AND BOUNDARY CONSTRAINTS 

      Velho, Luiz (Eurographics Association, 1990)
      This paper presents a method to generate a polygonal approximation of implicit surfaces. Space partitioning by simplicial decomposition is used to sample the surface, which provides an unambiguous framework for polygon ...

    • AN INTERACTIVE DEBUGGER FOR PHIGS 

      Howard, T.L.J.; Hewitt, W.T.; Larkin, S. (Eurographics Association, 1990)
      The Programmer’s Hierarchical Interactive Graphics System (PHIGS) is an International Standard for integrating application modelling and interactive computer graphics. With PHIGS, application models are constructed from ...

    • INTERPOLATING CURVE NETWORKS WITH NEW BLENDING PATCHES 

      Saitoh, Tsuyoshi; Hosaka, Mamoru (Eurographics Association, 1990)
      This paper describes methods of c o n s t r u c t i n g s u r f a c e patches which s a t i s f y independently given boundary conditions on a l l i t s four or t h r e e s i d e s . A patch c o n s i s t s of two p a r t ...

    • Factoring a Homogeneous Transformation for a more Efficient Graphics Pipeline 

      Abi-Ezzi, Salim S.; Wozny, Michael J. (Eurographics Association, 1990)
      We identify an intermediate coordinate system situated between world coordinates and display coordinates, which exhibits unique features for lighting calculations and for clipping in homogeneous coordinates. Our key ...

    • DaScript Plus A PostScript Extension supporting 3D Graphics with 2D Functionality 

      Samara, Veronika; Schaub, Jutta; Noll, Stefan (Eurographics Association, 1990)
      In the world of electronic publishing page description languages describe a very powerful interface between document creation software and raster output devices. 3D graphics systems offer the possibility to give a more or ...

    • Relaxed Multi-rate Systolic Array Graphics Engine for High Resolution Real-time Computer Graphics 

      Jayasinghe, J.A.K.S.; Herrmann, O.E. (Eurographics Association, 1990)
      Generation of realistic images while supporting faster interaction is a topic in computer graphics research which has drawn considerable attention. Conventional frame buffer has been identified as a major bottle-neck for ...

    • A PIPELINED-PARALLEL ARCHITECTURE FOR 2.5-D BATCH RASTERIZERS 

      Birk, Yitzhak; Mccrossin, lames M . (Eurographics Association, 1990)
      The emergence of application programs that take advantage of highly expressive page description languages has sharply increased the amount of computing required for rasterizing an average page, and single-microprocessor ...

    • Some Possible Applications of CORDIC Processors in Computer Graphics 

      Kocsis, F.; Böhme, J.F. (Eurographics Association, 1990)
      Some application possibilities of an ASIC-type processing element, the CORDIC processor, in computer graphics are discussed. CORDIC-based solutions are derived for some basic computer geometry computations: conversion ...

    • GEO++ - A System for Both Modelling and Display 

      Wisskirchen, Peter (Eurographics Association, 1989)
      We present a new concept for a graphics system which we call GEO++ . Apart from the manipulation of groups (structures in PHIGS-terminology), GEO++ permits a direct access to the tree structure required for display. With ...

    • The Use of Finite Element Theory for Simulating Object and Human Body Deformations and Contacts 

      Gourret, Jean-Paul; Magnenat-Thalmann, Nadia; Thalmann, Daniel (Eurographics Association, 1989)
      This paper presents a method for combining image synthesis and modeling based on a finite element method (FEM) to get realistic intelligent images. FEM is used for modeling both elastically and plastically deformations of ...

    • A Reference Model for the Visualisation of Multi-Dimensional Data 

      Bergeron, R. Daniel; Grinstein, Georges G. (Eurographics Association, 1989)
      This paper presents a reference model for the development of systems for the visualization of multidimensional data. The purpose of the reference model is to build a conceptual basis for thinking about multi-dimensional ...

    • Subdivisions of Surfaces and Generalized Maps 

      Lienhardt, Pascal (Eurographics Association, 1989)
      The modeling of subdivisions of surfaces is of greatest interest in Geometric Modeling (in particular for Boundary Representation) , and many works deal with the definition of models, which enable the representation of ...

    • Visualizing Curvature Discontinuities of Free-Form Surfaces 

      Pottmann, Helmut (Eurographics Association, 1989)
      A new method for the visualization of curvature discontinuities of free-form surfaces is presented. It is based upon an improvement and refinement of the well-known technique of displaying isophotes.
