    Neeman, Alisa G.; Brannon, Rebecca; Jeremic, Boris; Gelder, Allen Van; Pang, Alex (The Eurographics Association, 2008)
    Visualization of fourth-order tensors from solid mechanics has not been explored in depth previously. Challenges include the large number of components (3x3x3x3 for 3D), loss of major symmetry and loss of positive definiteness ...
  • Pre-Integrated Volume Rendering for Multi-Dimensional Transfer Functions 

    Kraus, M. (The Eurographics Association, 2008)
    This work presents an efficient extension of pre-integrated volume rendering for multi-dimensional transfer functions. Since even two-dimensional transfer functions can result in strong rendering artifacts that cannot be ...

    Hernell, Frida; Ljung, Patric; Ynnerman, Anders (The Eurographics Association, 2008)
    A novel technique for efficient computation of global light propagation in interactive DVR is presented in this paper. The approach is based on a combination of local shadows from the vicinity of each voxel with global ...
  • GPU-based Particle Systems for Illustrative Volume Rendering 

    Pelt, R.F.P. van; Vilanova, A.; Wetering, H.M.M. van de (The Eurographics Association, 2008)
    Illustrative techniques are generally applied to produce stylized renderings. Various illustrative styles have been applied to volumetric data sets, producing clearer images and effectively conveying visual information. ...
  • Isosurface Ambient Occlusion and Soft Shadows with Filterable Occlusion Maps 

    Penner, Eric; Mitchell, Ross (The Eurographics Association, 2008)
    Volumetric data sets are often examined by displaying isosurfaces, surfaces where the data or function takes on a given value. We propose a new method for rendering isosurfaces at interactive rates while supporting dynamic ...
  • Stereo Pseudo 3D Rendering for Web-based Display of Scientific Volumetric Data

  • Layers for Effective Volume Rendering 

    Raman, S.; Mishchenko, O.; Crawfis, R. (The Eurographics Association, 2008)
    A multi-layer volume rendering framework is presented. The final image is obtained by compositing a number of renderings, each being represented as a separate layer. This layer-centric framework provides a rich set of 2D ...
  • Multiresolution Interval Volume Meshes 

    Weiss, Kenneth; Floriani, Leila De (The Eurographics Association, 2008)
    Interval volumes are a generalization of isosurfaces that represent the set of points between two surfaces. In this paper, we present a compact multi-resolution representation for interval volume meshes extracted from ...

    Wang, Cuilan; Newman, Timothy S.; Lee, Jong Kwan (The Eurographics Association, 2008)
    Representational accuracy of the isosurface meshes produced by well-known marching isosurfacing methods is considered. Accuracy is determined versus the isosurface given by trilinear interpolation and quantified using a ...
