    • Adaptive Enumeration of Implicit Surfaces with Affine Arithmetic 

      de Figueiredo, Luiz Henrique; Stolfi, Jorge (Blackwell Science Ltd and the Eurographics Association, 1996)
      We discuss adaptive enumeration and rendering methods for implicit surfaces, using octrees computed with affine arithmetic, a new tool for range analysis. Affine arithmetic is similar to standard interval arithmetic, but ...

    • Adaptive Sampling of Implicit Surfaces for Interactive Modelling and Animation 

      Desbrun, Mathieu; Tsingos, Nicolas; Gascuel, Marie-Paule (Blackwell Science Ltd and the Eurographics Association, 1996)
      This paper presents a new adaptive sampling method for implicit surfaces that can be used in both interactive modelling and animation. The algorithm samples implicit objects composed of blending primitives and efficiently ...

    • Approximate Conversion of Parametric to Implicit Surfaces 

      Velho, Luiz; Gomes, Jonas (Blackwell Science Ltd and the Eurographics Association, 1996)
      In this paper we present a framework for the approximate conversion of parametric to implicit surfaces. It takes as input a parametric description and generates a piecewise analytic implicit representation. The conversion ...

    • Efficient Hierarchical Refinement and Clustering for Radiosity in Complex Environments 

      Gibson, S.; Hubbold, R.J. (Blackwell Science Ltd and the Eurographics Association, 1996)
      Generating accurate radiosity solutions of very complex environments is a time-consuming problem. We present a rapid hierarchical algorithm that enables such solutions to be computed quickly and efficiently. Firstly, a new ...

    • The Production of Volume Data from Triangular Meshes Using Voxelisation 

      Jones, Mark W. (Blackwell Science Ltd and the Eurographics Association, 1996)
      Voxelisation is the term given to the process of converting data from one source type into a three dimensional volume of data values. The techniques known collectively as volume visualisation can then be applied to the ...
