    • Dynamic Load Balancing for Parallel Volume Rendering 

      Marchesin, Stéphane; Mongenet, Catherine; Dischler, Jean-Michel (The Eurographics Association, 2006)
      Parallel volume rendering is one of the most efficient techniques to achieve real time visualization of large datasets by distributing the data and the rendering process over a cluster of machines. However, when using level ...
    • Optimized Volume Raycasting for Graphics-Hardware-based Cluster Systems 

      Müller, C.; Strengert, M.; Ertl, T. (The Eurographics Association, 2006)
      In this paper, we present a sort-last parallel volume rendering system based on single-pass volume raycasting performed in the fragment shader unit. The architecture is aimed for displaying data sets that utilize the total ...

      Thomaszewski, B.; Blochinger, W. (The Eurographics Association, 2006)
      The physically based simulation of clothes in virtual environments is a highly demanding problem. It involves both modeling the internal material properties of the textile and the interaction with the surrounding scene. ...
    • Parallelization of Inverse Design of Luminaire Reflectors 

      Magallon, J. A.; Patow, G.; Seron, F. J.; Pueyo, X. (The Eurographics Association, 2006)
      This paper presents the parallelization of techniques for the design of reflector shapes from prescribed optical properties (far-field radiance distribution), geometrical constraints and, if available, a user-given initial ...
    • Interactive Volume Rendering of Unstructured Grids with Time-Varying Scalar Fields
