    • 3D Display: Synthetic Image Generation and Visual Effect Simulation 

      Theoharis, T. A.; Travis, A. R. L.; Wiseman, N. E. (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      Two viewing models are presented for a promising type of three dimensional display: they are based on parallel oblique and perspective oblique projections respectively. A detailed simulation compares the quality of the ...

    • 3D MODELLING AND MOTION OF DEFORMABLE SOLIDS FROM 2D IMAGES 

      Neveu, Marc; Faudot, Dominique (Eurographics Association, 1990)
      Our work purpose is to elaborate a geometric and motional model for deformable solids, known only by a very small number of general crosssections images. We start from a generic 3D model of the studied solid we distort ...

    • 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 Approach to Hierarchical Input Devices 

      Duce, D. A.; Liere, R van; Hagen, P.J.W. ten (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      This paper shows how a formal description of the GKS input model can be extended to include hierarchically structured input devices

    • AN APPROACH TO IMPROVE THE RELIABILITY OF BOOLEAN OPERATION ON A PAIR OF POLYHEDRA 

      Li, Xinyou; Sun, Jiaguang; Tang, Zesheng (Eurographics Association, 1990)
      It is essential and pressing to improve reliability of Boolean operations in geometric modelling systems. The Boolean operations in commercial systems now available are not reliable enough because of numerical calculation ...

    • AN APPROACH TO THE FORMAL SPECIFICATION OF THE COMPONENTS OF AN INTERACTION 

      Faconti, Giorgio P.; Paterno, Fabio (Eurographics Association, 1990)
      In this paper we present the preliminary results from a work aiming to the formal specification af a model suitable for the description of interactive graphics program within the framework defined by the Reference Model ...

    • The Architecture of a Prototype System for Drawing Data Structures 

      Ding, Chen; Mateti, Prabhaker (Eurographics Association, 1990)
      Automatic drawing of aesthetically pleasing data structure diagrams is a challenging problem which has attracted much research attention. In building such a system, we are confronted with four basic problems: (1) proper ...

    • AUTOMATIC MODELLING OF NATURAL SCENES FOR GENERATING SYNTHETIC MOVIES 

      Koch, Reinhard (Eurographics Association, 1990)
      A model based analysis by synthesis algorithm is presented. It combines image analysis and synthesis techniques to obtain a three dimensional scene description and to generate synthetic movies out of that scene description. ...

    • A Browser for Large Directed Graphs 

      Bovey, J. D. (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      The paper describes an experimental graph browsing tool which provides fast interactive browsing on very large graphs. The particular graph for which the program was developed is based on the distributed tile system of a ...

    • CHARACTERIZATION OF TOPOGRAPHIC SURFACES 

      Falcidieno, Bianca; Spagnuolo, Michela (Eurographics Association, 1990)
      This paper presents a method for extracting and representang features of a topographic surface approximated by triangular tales An algorithm as given which computes characteristic regions (a. e. regions having concave, ...

    • COLOR IMAGE RECONSTRUCTION FROM NONUNIFORM SPARSE SAMPLES USING A THIN PLATE MODEL 

      Metaxas, Dimitris; Milios, Evangelos (Eurographics Association, 1990)
      In this paper we solve the problem of reconstructing a color image from sparse, noisy, and nonuniformly distributed color measurements. We apply a method for reconstructing a surface from sparse depth measurements to each ...

    • 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: ...

    • Combining Graphics and Windowing Standards in the XGKS System 

      Rogers, Greg; Sung, Kelvin; Kubitz, William (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      In the past few years we have seen the acceptance of standards for both two and three dimensional computer graphics. Also during this time, the workstation community has converged on a common windowing system. This paper ...
