    • 3D Interaction with the Desktop Bat 

      Steed, Anthony; Slater, Mel (Blackwell Science Ltd and the Eurographics Association, 1995)
      Many applications now demand interaction with visualizations of 3D scenes and data sets. Current flat 2D displays are limited in their capacity to provide this not only by the display technology but the interaction metaphors ...
    • Fast Generation of Leakproof Surfaces from Well-Defined Objects by a Modified Marching Cubes Algorithm 

      Roll, Stefan; Haase, Axel; von Kienlin, Markus (Blackwell Science Ltd and the Eurographics Association, 1995)
      Local surface reconstruction by the Marching Cubes algorithm and its derivatives has a well known ambiguity, which prevents constructed surfaces from being closed and simple. We investigate this ambiguity assuming that a ...
    • Colouration Issues in Computer Generated Facial Animation 

      Patel, M. (Blackwell Science Ltd and the Eurographics Association, 1995)
      In everyday interactions with one another we use the face for recognising people and for communicating with them. Despite the considerable amount of research into computer generated facial animation, one particular aspect, ...
    • Collision Detection for Animation using Sphere-Trees 

      Palmer, I. J.; Grimsdale, R. L. (Blackwell Science Ltd and the Eurographics Association, 1995)
      The detection of collisions between moving polyhedral objects is one of the most computationally intensive tasks in the computer animation process. The use of object-oriented techniques to encapsulate data within the objects ...
    • Optimised CSG Tree Evaluation for Space Subdivision 

      Zemcik, Pavel; Chalmers, Alan (Blackwell Science Ltd and the Eurographics Association, 1995)
      Ray tracing is a well known technique for producing realistic computer images. The computational requirements of this method are such that optimisation techniques, for example space subdivision, must be used if complex ...
    • Fractals and Quasi-Affine Transformations 

      Nehlig, P. W.; Reveilles, J.-P. (Blackwell Science Ltd and the Eurographics Association, 1995)
      In the continuum , contracting affine transformations have a unique fixed point. It is well known that this property is not preserved by dicretization and that the dynamics of discretized functions are very complicated. ...
