    • Decomposition and Visualization of Fourth-Order Elastic-Plastic Tensors 

      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 ...

    • Obscurance-based Volume Rendering Framework 

      Ruiz, M.; Boada, I.; Viola, I.; Bruckner, S.; Feixas, M.; Sbert, M. (The Eurographics Association, 2008)
      Obscurances, from which ambient occlusion is a particular case, is a technology that produces natural-looking lighting effects in a faster way than global illumination. Its application in volume visualization is of special ...

    • 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 ...

    • Stereo Pseudo 3D Rendering for Web-based Display of Scientific Volumetric Data 

      Eng, Daniel Chern-Yeow; Choe, Yoonsuck (The Eurographics Association, 2008)
      Advancement in high-throughput microscopy technology such as the Knife-Edge Scanning Microscopy (KESM) is enabling the production of massive amounts of high-resolution volumetric data of biological microstructures. To fully ...

    • 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 ...

    • Stroke-Based Transfer Function Design 

      Ropinski, T.; Praßni, J.; Steinicke, F.; Hinrichs, K. (The Eurographics Association, 2008)
      In this paper we propose a user interface for the design of 1D transfer functions. The user can select a feature of interest by drawing one or more strokes directly onto the volume rendering near its silhouette. Based on ...

    • On Accuracy of Marching Isosurfacing Methods 

      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 ...

    • Harmonic Colormaps for Volume Visualization 

      Wang, Lujin; Mueller, Klaus (The Eurographics Association, 2008)
      Color design forms a crucial part in visual aesthetics, and it has been shown that a visually aesthetic visualization will be looked at more carefully. An important role plays here the choice of a colormap that is composed ...

    • A Survey of Methods for Moving Least Squares Surfaces 

      Cheng, Z.-Q.; Wang, Y.-Z.; Li, B.; Xu, K.; Dang, G.; Jin, S.-Y. (The Eurographics Association, 2008)
      Moving least squares (MLS) surfaces representation directly defines smooth surfaces from point cloud data, on which the differential geometric properties of point set can be conveniently estimated. Nowadays, the MLS surfaces ...

    • Parallel Construction of k-Nearest Neighbor Graphs for Point Clouds 

      Connor, M.; Kumar, P. (The Eurographics Association, 2008)
      We present a parallel algorithm for k-nearest neighbor graph construction that uses Morton ordering. Experiments show that our approach has the following advantages over existing methods: (1) Faster construction of k-nearest ...

    • A Graph-Based Approach to Symmetry Detection 

      Berner, A.; Bokeloh, M.; Wand, M.; Schilling, A.; Seidel, H.-P. (The Eurographics Association, 2008)
      Symmetry detection aims at discovering redundancy in the form of reoccurring structures in geometric objects. In this paper, we present a new symmetry detection algorithm for geometry represented as point clouds that is ...
