  • A Multiprocessor Implementation of Radiosity 

    Ng, Adelene; Slater, Mel (Blackwell Science Ltd and the Eurographics Association, 1993)
    This paper describes a multi-processor implementation of form factor computation in the radiosity method. Form factors are computed using the ray casting method and the algorithm is enhanced with Binary Space Partition ...
  • Graphic Objects: A Mathematical Abstract Model for Computer Graphics 

    Torres, J.C.; Clares, B. (Blackwell Science Ltd and the Eurographics Association, 1993)
    This paper defines an abstract mathematical model for graphic systems which incorporates modelling operations. The model is based on the"graphic object" concept. A graphic object is an abstraction of a graphic entity. ...
  • A Fractal Method for Digital Elevation Model Construction and its Application to a Mountain Region 

    Brivio, Pietro Alessandro; Marini, Daniele (Blackwell Science Ltd and the Eurographics Association, 1993)
    This paper presents and discusses the results of a methodology for the construction of Digital Elevation Models (DEM), based on mathematical principles of fractal geometry. Classical approaches to DEM are founded on numerical ...
  • The Method of Dynamic Palette Construction in Realistic Visualization Systems 

    Voloboj, Aleksej G. (Blackwell Science Ltd and the Eurographics Association, 1993)
    The paper describes the colour approximation problem and the method of dynamic palette construction is suggested for its solution. The method uses the graphic display palette based on the computed true colour of the ...
  • ANIMA: An Interactive Tool for Scientific Data Animation 

    Moltedo, Laura; Morigi, Serena (Blackwell Science Ltd and the Eurographics Association, 1993)
    This paper describes an animation interactive system that produces image sequences used to study the numerical results of scientific simulations. The fundamental goal of the system is to provide an easy method for observing ...
