    Lundin, Karljohan; Lundström, Claes; Cooper, Matthew; Ynnerman, Anders (The Eurographics Association, 2006)
    Direct volume haptics can provide both guidance and extra information during exploration of volumetric data. In this paper we present a novel approach to volume haptics enabling haptic exploration of tissue shape, borders ...
  • Contour-Based Surface Reconstruction using Implicit Curve Fitting, and Distance Field Filtering and Interpolation 

    Marker, Jeffrey; Braude, Ilya; Museth, Ken; Breen, David (The Eurographics Association, 2006)
    This paper presents a volumetric approach to reconstructing a smooth surface from a sparse set of paral- lel binary contours, e.g. those produced via histologic imaging. It creates a volume dataset by interpolating 2D ...
  • SIMD-Aware Ray-Casting 

    Leung, Warren; Neophytou, Neophytos; Mueller, Klaus (The Eurographics Association, 2006)
    With the addition of loop and branch capabilities into the GPU programming set, a more natural and free-flowing volume rendering pipeline execution mode recently emerged. While the execution of the looped fragment program ...
  • Pre-integrated Flow Illustration for Tetrahedral Meshes 

    Svakhine, N. A.; Ebert, D.; Tejada, E.; Ertl, T.; Gaither, K. (The Eurographics Association, 2006)
    Previous work has demonstrated the clarity and usefulness of illustrative techniques for visualizing flow data. However, previous systems were limited to applying these techniques to uniform grids. Since unstructured grids ...

  • GPU-Accelerated D2VR 

    Xu, Fang; Mueller, Klaus (The Eurographics Association, 2006)
