  • 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. ...
  • Berger, Marc; Levit, Nancy; Trout, Terry (Eurographics Association, 1990)
    The past few years have seen some very impressive results in rendering natural phenomena. This paper addresses the problem of how to model and render optical illusions brought about by atmospheric refraction. Refraction ...
  • Sousa, A. Augusto; Costa, Antonio M. C.; Ferreira, Fernando N. (Eurographics Association, 1990)
    The generation of highly realistic images using the conventional Ray-Tracing algorithm, in CAD environments, is totally out of the question if we consider the interactive requirements of most CAD systems. In this paper, ...
  • Lewis, Robert R. (Eurographics Association, 1990)
    This paper describes a way to perform realistic three-dimensional texturing of ray-traced objects with irregular surfaces. Such texturing has teen done in the past with texture mapping, particle systems, or volumetric ...
  • 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, ...
  • Fellner, Dieter W.; Kappe, F. (Eurographics Association, 1990)
    Systems allowing the creation and manipulation of graphical information (so-called Graphic Editors) have become essential in various fields of applications. At the same time the typical user of such a system has changed. ...
  • Anjyo, Ken-ichi (Eurographics Association, 1990)
    Semi-globalized spectral synthesis is proposed as a new tool for three-dimensional scene description consisting of many natural objects, such as terrain, sea waves, and clouds. The method is based on the mathematical theory ...
  • Bieri, Hanspeter (Eurographics Association, 1990)
    Hyperimages represent a variation of the conventional digital images which implies pixels of different dimensions within the same image. The extent of a hyperimage is the disjoint union of all pixel extents it contains, ...
  • Dong, Jun-Cai; Peng, Qun-Sheng; Liang, You-Dong (Eurographics Association, 1990)
    A new functional modeling approach - -functional modeling, is presented to depict various classes of natural terrain. While this approach possesses the functions of several previous methods, it does not suffer the drawbacks ...
  • Higashi, Masatake; Kushimoto, Takuya; Hosaka, Mamoru (Eurographics Association, 1990)
    For evaluating quality of free-form surfaces and visualizing their features, various curves on a surface, which characterize its properties, are defined and their equations are deduced. Newly introduced curves include those ...
