      Broersen, Alexander; Liere, Robert van; Heeren, Ron M. A. (The Eurographics Association, 2007)
      An imaging mass spectrometer is an analytical instrument that can determine the spatial distribution of chemical compounds on complex surfaces. The output of the device is a multi-spectral datacube; a three-dimensional ...
    • Path Visualization for Adjacency Matrices 

      Shen, Zeqian; Ma, Kwan-Liu (The Eurographics Association, 2007)
      For displaying a dense graph, an adjacency matrix is superior than a node-link diagram because it is more compact and free of visual clutter. A node-link diagram, however, is far better for the task of path finding because ...
    • Dimensional Congruence for Interactive Visual Data Mining and Knowledge Discovery 

      Baumgaertner, Sebastian; Ebert, Achim; Deller, Matthias (The Eurographics Association, 2007)
      Many authors in the field of 3D human computer interaction have described the advantages of 3D user interfaces: Intuitive metaphors from daily life, immersive workspaces, virtual environments that closely resemble natural ...
    • TrustNeighborhoods: Visualizing Trust in Distributed File Sharing Systems 

      Elmqvist, Niklas; Tsigas, Philippas (The Eurographics Association, 2007)
      We present TrustNeighborhoods, a security trust visualization for situational awareness on the Internet aimed at novice and intermediate users of a distributed file sharing system. The TrustNeighborhoods technique uses the ...
    • Multi-Resolution Techniques for Visual Exploration of Large Time-Series Data 

      Hao, Ming; Dayal, Umeshwar; Keim, Daniel; Schreck, Tobias (The Eurographics Association, 2007)
      Time series are a data type of utmost importance in many domains such as business management and service monitoring. We address the problem of visualizing large time-related data sets which are difficult to visualize ...
    • Hardware-accelerated Stippling of Surfaces derived from Medical Volume Data 

      Baer, Alexandra; Tietjen, Christian; Bade, Ragnar; Preim, Bernhard (The Eurographics Association, 2007)
      We present a fast hardware-accelerated stippling method which does not require any preprocessing for placing points on surfaces. The surfaces are automatically parameterized in order to apply stippling textures without ...
    • Integrating Local Feature Detectors in the Interactive Visual Analysis of Flow Simulation Data 

      Buerger, Raphael; Muigg, Philipp; Ilcík, Martin; Doleisch, Helmut; Hauser, Helwig (The Eurographics Association, 2007)
      We present smooth formulations of common vortex detectors that allow a seamless integration into the concept of interactive visual analysis of flow simulation data. We express the originally binary feature detectors as ...
    • Subdivision Volume Splatting 

      McDonnell, Kevin T.; Neophytou, Neophytos; Mueller, Klaus; Qin, Hong (The Eurographics Association, 2007)
      Volumetric Subdivision (VS) is a powerful paradigm that enables volumetric sculpting and realistic volume deformations that give rise to the concept of "virtual clay". In VS, volumes are commonly represented as a space-filling ...
    • Online Dynamic Graph Drawing 

      Frishman, Yaniv; Tal, Ayellet (The Eurographics Association, 2007)
