  • Multi-layer Depth Peeling by Single-Pass Hardware Rasterisation for Faster Isosurface Raytracing on a GPU 

    Liu, Baoquan; Clapworthy, Gordon J.; Dong, Feng (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Empty-space skipping is an essential acceleration technique for volume rendering. Image-order empty-space skipping is not well suited to GPU implementation, since it must perform checks on, essentially, a per-sample basis, ...

    Molchanov, Vladimir; Rosenthal, Paul; Linsen, Lars (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Signed distance functions (SDF) to explicit or implicit surface representations are intensively used in various computer graphics and visualization algorithms. Among others, they are applied to optimize collision detection, ...
  • Topology-based Smoothing of 2D Scalar Fields with C1-Continuity 

    Weinkauf, Tino; Gingold, Yotam; Sorkine, Olga (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Data sets coming from simulations or sampling of real-world phenomena often contain noise that hinders their processing and analysis. Automatic filtering and denoising can be challenging: when the nature of the noise is ...
  • Visualization and Analysis-Oriented Reconstruction of Material Interfaces 

    Meredith, Jeremy; Childs, Hank (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Reconstructing boundaries along material interfaces from volume fractions is a difficult problem, especially because the under-resolved nature of the input data allows for many correct interpretations. Worse, algorithms ...
  • Understanding Interactive Legends: a Comparative Evaluation with Standard Widgets 

    Riche, Nathalie Henry; Lee, Bongshin; Plaisant, Catherine (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Interactive information visualization systems rely on widgets to allow users to interact with the data and modify the representation. We define interactive legends as a class of controls combining the visual representation ...
  • The Readability of Path-Preserving Clusterings of Graphs 

    Archambault, Daniel; Purchase, Helen C.; Pinaud, Bruno (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Graph visualization systems often exploit opaque metanodes to reduce visual clutter and improve the readability of large graphs. This filtering can be done in a path-preserving way based on attribute values associated with ...
  • A Salience-based Quality Metric for Visualization 

    Jänicke, Heike; Chen, Min (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Salience detection is a principle mechanism to facilitate visual attention. A good visualization guides the observer s attention to the relevant aspects of the representation. Hence, the distribution of salience over a ...
  • The Perception of Correlation in Scatterplots 

    Rensink, Ronald A.; Baldridge, Gideon (The Eurographics Association and Blackwell Publishing Ltd., 2010)
  • Toward a Lagrangian Vector Field Topology 

    Fuchs, Raphael; Peikert, Ronny; Kemmler, Jan; Schindler, Benjamin; Waser, Juergen; Sadlo, Filip; Hauser, Helwig (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    In this paper we present an extended critical point concept which allows us to apply vector field topology in the case of unsteady flow.We propose a measure for unsteadiness which describes the rate of change of the ...
  • A Maximum Enhancing Higher-Order Tensor Glyph 

    Schultz, Thomas; Kindlmann, Gordon (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Glyphs are a fundamental tool in tensor visualization, since they provide an intuitive geometric representation of the full tensor information. The Higher-Order Maximum Enhancing (HOME) glyph, a generalization of the ...
  • Topology Aware Stream Surfaces 

    Schneider, Dominic; Reich, Wieland; Wiebel, Alexander; Scheuermann, Gerik (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    We present an algorithm that allows stream surfaces to recognize and adapt to vector field topology. Standard stream surface algorithms either refine the surface uncontrolled near critical points which slows down the ...
  • Visual Analysis of Multi-Joint Kinematic Data 

    Krekel, Peter R.; Valstar, Edward R.; Groot, Jurriaan de; Post, Frits H.; Nelissen, Rob G. H. H.; Botha, Charl P. (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Kinematics is the analysis of motions without regarding forces or inertial effects, with the purpose of understanding joint behaviour. Kinematic data of linked joints, for example the upper extremity, i.e. the shoulder and ...
  • An Evaluation of Glyph Perception for Real Symmetric Traceless Tensor Properties 

    Jankun-Kelly, T. J.; Lanka, Yagneshwara; II, J. Edward Swan (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    A perceptual study of four tensor glyphs for symmetric, real, traceless tensors was performed. Each glyph encodes three properties of the system: Orientation, uniaxiality (alignment along the direction of orientation), and ...
  • ProbExplorer: Uncertainty-guided Exploration and Editing of Probabilistic Medical Image Segmentation 

    Saad, Ahmed; Möller, Torsten; Hamarneh, Ghassan (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    In this paper, we develop an interactive analysis and visualization tool for probabilistic segmentation results in medical imaging. We provide a systematic approach to analyze, interact and highlight regions of segmentation ...
  • Reusable Visualizations and Animations for Surgery Planning 

    Mühler, Konrad; Preim, Bernhard (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    For surgical planning, the exploration of 3D visualizations and 2D slice views is essential. However, the generation of visualizations which support the specific treatment decisions is very tedious. Therefore, the reuse ...
  • Visual Support for Interactive Post-Interventional Assessment of Radiofrequency Ablation Therapy 

    Rieder, Christian; Weihusen, Andreas; Schumann, Christian; Zidowitz, Stephan; Peitgen, Heinz-Otto (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Percutaneous radiofrequency (RF) ablation is a minimally invasive, image-guided therapy for the treatment of liver tumors. The assessment of the ablation area (coagulation) is performed to verify the treatment success as ...
  • Topographic Map Visualization from Adaptively Compressed Textures 

    Andujar, Carlos (The Eurographics Association and Blackwell Publishing Ltd., 2010)
    Raster-based topographic maps are commonly used in geoinformation systems to overlay geographic entities on top of digital terrain models. Using compressed texture formats for encoding topographic maps allows reducing ...
