    • Simplification of Global-Illumination Meshes 

      Hughes, Merlin; Lastra, Anselmo A.; Saxe, Edward (Blackwell Science Ltd and the Eurographics Association, 1996)
      We present a methodfor simplifying the meshes produced as solutions to global illumination problems, reducing geometric complexity while retaining the perceived imagefidelity. The method has been applied to produce meshes ...

    • Special Effects with Half-Toning 

      Buchanan, John W. (Blackwell Science Ltd and the Eurographics Association, 1996)
      Half-toning is the process by which gray-scale images are approximated with sets of black and white pixels. The process works because our eyes perceive a local average, thus half-toning seeks to approximate the local ...

    • Surface Graph Sketching 

      Hutchinson, D.; Lin, F.; Hewitt, W.T. (Blackwell Science Ltd and the Eurographics Association, 1996)
      The production of patterns and designs upon surfaces has received only limited attention, with texturing techniques being accepted as adequate. Texturing, however, can be a very unsatisfactory and clumsy method of producing ...

    • Symbiosis of Virtual Reality and Scientific Visualization System 

      Haase, Helmut (Blackwell Science Ltd and the Eurographics Association, 1996)
      This paper describes a concept for the symbiosis of a virtual reality system and a system for scientific visualization, as well as an implementation (called ISVAS-VR) to evaluate the concept. The idea is to preserve the ...

    • A Three Dimensional Image Cache for Virtual Reality 

      Schaufler, Gernot; Sturzlinger, Wolfgang (Blackwell Science Ltd and the Eurographics Association, 1996)
      Despite recent advances in rendering hardware, large and complex virtual environments cannot be displayed with a sufficiently highframe rate, because of limitations in the available rendering performance.This paper presents ...

    • Three-Dimensional Modeling and Effects on Still Images 

      Zakait, Yaron; Rappoport, Ari (Blackwell Science Ltd and the Eurographics Association, 1996)
      Designers and creative artists use computer graphics and image processing effects on stall photographs in application areas such as advertising entertainment broadcasting and the arts Most of the effects available in ...

    • Vector Field Based Texture Mapping of Animated Implicit Objects 

      Smets-Solanes, Jean-Paul (Blackwell Science Ltd and the Eurographics Association, 1996)
      This paper shows that an adequate use of vectorfields can solve most inconsistencies related to texture mapping that appear in current animation and rendering systems based on implicit objects. The method used is based on ...
