  • Johnson, C.W.; Harrison, M.D. (Eurographics Association, 1990)
    Formal specifications provide the non-specialist with an extremely poor impression of what it would be like to interact with a computer system. Prototypes provide a far better impression of the ‘look and feel’ of possible ...
  • 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 ...
  • Sakas, Georgios (Eurographics Association, 1990)
    In recent years a number of techniques have been developed for rendering volume effects (haze, fog, smoke, clouds, etc.). These techniques are either time consuming (ray-tracing, radiosity) or do not account for arbitrary ...
  • Torres, Enric (Eurographics Association, 1990)
    This paper describes an improvement of the generation of BSP trees and its utilization in the visualization of dynamic polyhedral scenes. Dynamic BSP trees, a new six-level structure, are presented. Dynamic BSP trees are ...
  • Thirion, Jean-Philippe (Eurographics Association, 1990)
    Tries are data structures used for multidimensional searching. We introduce an original method to build Tries for a set of convex polyhedra, weshow how Tries can be used for Ray tracing and we compare them with other data ...
  • Koivunen, Marja-Riitta (Eurographics Association, 1990)
    This paper describes Window Strategies Environment (WSE), which is an environment for exploring different window strategies. It is a tool for developers who want to implement and explore different window strategies easily. ...
  • Meyer, Urs (Eurographics Association, 1990)
    This paper presents a new ray-tracing technique for generating soft shadows. The technique treats scenes consisting of light sources and opaque objects which are polygons or polyhedra of arbitrary shape and size. To determine ...
  • Poulin, Pierre; Amanatides, John (Eurographics Association, 1990)
    In virtually all rendering systems, linear light sources are modeled with a series of point light sources that require considerable computing resources to produce realistic looking results. A general solution for shading ...
  • Ramstein, G. (Eurographics Association, 1990)
    This paper presents a method using stochastic models for the simulation and interpolation of natural phenomena. These models are based on the general concept of random functions with stationary increments, to which the fbm ...
  • Girard, P.; Pierra, G.; Guittet, L. (Eurographics Association, 1990)
    In recent years, the number of computer end-users who do not know programming has increased rapidly. This new phenomenon has spurred a great deal of research about program design using very different approaches from the ...
  • 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 ...
  • 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, ...
  • Slusallek, Philipp B.; Seidel, Hans-Peter (Eurographics Association, 1990)
    TRIMO has been designed as a workstation-based interactive system for the generation, manipulation, and display of surfaces over arbitrary toplogical meshes. In addition to rational tensor product Bezier and B-spline ...
  • 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 ...
  • 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 ...
  • Cesar, Christian L. (Eurographics Association, 1990)
    A 3D graphics extension to the PostScript language is proposed. The extension maintains the same graphic programming style that characterizes the language's 2D environment. The extensions proposed cover 3D graphics state, ...
  • 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 ...
  • 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 ...
  • Scheller, Angela; Fuhrhop, Christian (Eurographics Association, 1990)
    This paper presents DAPHNE, a document processing system for joint editing within the German Research Network DFN. DAPHNE is based on two international standards in the area of document and graphics processing, the Standard ...
  • 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 ...
