    • A Simple Description of Complex Curves 

      Bouras, A.; Shariat, B.; Vandorpe, D. (Blackwell Science Ltd and the Eurographics Association, 1992)
      In this paper, we propose a method of complex curves description, based on the use of standard primitives (curve arcs), inscribed in including boxes. This method simplifies the creation steps (curves are not defined with ...
    • Simulation of Facial Muscle Actions Based on Rational Free Form Deformations 

      Kalra, Prem; Mangili, Angelo; Thalmann, Nadia Magnenat; Thalmann, Daniel (Blackwell Science Ltd and the Eurographics Association, 1992)
      This paper describes interactive facilities for simulating abstract muscle actions using Rational Free Form Deformations (RFFD). The particular muscle action is simulated as the displacement of the control points of the ...
    • Stochastic Motion-Motion Under the Influence of Wind 

      Shinya, Mikio; Fournier, Alain (Blackwell Science Ltd and the Eurographics Association, 1992)
      Stochastic approaches are very effective for modelling natural phenomena. This paper presents a motion model based on a stochastic process as well as physics, and proposes motion synthesis techniques for stochastic ...
    • SX/Tools - An Open Design Environment for Adaptable Multimedia User Interfaces 

      Kuhme, Thomas; Schneider-Hufschmidt, Matthias (Blackwell Science Ltd and the Eurographics Association, 1992)
      In this paper a brief review of user interface management systems (UIMSs) and their advantages is given. Shortcomings of current UIMSs and open requirements imposed by industrial application areas are outlined. Among the ...
    • Template-Based Volume Viewing 

      Yagel, Roni; Kaufman, Arie (Blackwell Science Ltd and the Eurographics Association, 1992)
      We present an efficient three-phase algorithm for volume viewing that is based on exploiting coherency between rays in parallel projection. The algorithm starts by building a ray-template and determining a special plane ...
    • Two-manifold cell-decomposition of r-sets. 

      Falcidieno, Bianca; Ratto, Ornella (Blackwell Science Ltd and the Eurographics Association, 1992)
      This paper discusses the relationships studied between manifold solids and r-sets by defining an r-set as a decomposition in two-manifold cells. This decomposition is represented as a graph (Two-manifold Cell Decomposition ...
    • A Unified Approach for Physical and Geometric Modeling for Graphics and Animation 

      Essa, Irfan A.; Sclaroff, Stan; Pentland, Alex (Blackwell Science Ltd and the Eurographics Association, 1992)
      We present a unified approach for geometric and physical modeling using implicit functions, for application to graphics and animation. This method extends previously proposed techniques, and allows the standard finite ...
    • Visual Composition and Multimedia 

      de Mey, Vicki; Breiteneder, Christian; Dami, Laurent; Gibbs, Simon and Tsichritzis, Dennis (Blackwell Science Ltd and the Eurographics Association, 1992)
      Multimedia applications can be seen as sets of autonomous parts, independent yet capable of working together. This assumption allows for the construction of multimedia applications in a"connectionist" fashion. In this paper ...
    • The Visualization Input Pipeline - Enabling Semantic Interaction in Scientific Visualization 

      Felger, W.; Schroder, F. (Blackwell Science Ltd and the Eurographics Association, 1992)
      Scientific Visualization systems are primarily output-oriented, Users can specify and change parameters that are controlling the visualization process, which will result in different data representations or images respectively. ...
