    • Visibility-Driven Depth Determination of Surface Patches in Direct Volume Rendering 

      Stoppel, Sergej; Hege, Hans-Christian; Wiebel, Alexander (The Eurographics Association, 2014)
      This paper presents an algorithm called surfseek for selecting surfaces on the most visible features in directvolume rendering (DVR). The algorithm is based on a previously published technique (WYSIWYP) for picking 3Dlocations ...
    • Visualizing Graphs as Maps with Contiguous Regions 

      Kobourov, Stephen; Pupyrev, Sergey; Simonetto, Paolo (The Eurographics Association, 2014)
      Relational datasets, which include clustering information, can be visualized with tools such as BubbleSets, Line-Sets, SOM, and GMap. The countries in SOM-based and GMap-based visualizations are fragmented, i.e., theyare ...
    • Visualizing Uncertainty in HARDI Tractography Using Superquadric Streamtubes 

      Wiens, Vitalis; Schlaffke, Lara; Schmidt-Wilcke, Tobias; Schultz, Thomas (The Eurographics Association, 2014)
      Standard streamtubes for the visualization of diffusion MRI data are rendered either with a circular or with anelliptic cross section whose aspect ratio indicates the relative magnitudes of the medium and minor ...
    • Vortex Detection in 4D MRI Data: Using the Proper Orthogonal Decomposition for Improved Noise-Robustness 

      Carnecky, Robert; Brunner, Thomas; Born, Silvia; Waser, Jürgen; Heine, Christian; Peikert, Ronald (The Eurographics Association, 2014)
      Recent advances in magnetic resonance imaging (MRI) technology enabled the acquisition of time-resolved 3Dblood flow data. Several flow visualization methods have been applied to these data in order to investigate linksbetween ...
