      Andrews, Keith; Wright, Benedict (The Eurographics Association, 2014)
      Much attention has been focused on the provision of information graphics and visualisations inside a web browser.Currently available infovis toolkits produce graphical output by either injecting SVG nodes into the DOM ...
    • Extracting Jacobi Structures in Reeb Spaces 

      Chattopadhyay, Amit; Carr, Hamish; Duke, David; Geng, Zhao (The Eurographics Association, 2014)
      Jacobi sets have been identified as significant in multi-field topological analysis, but are defined in the domain ofthe data rather than in the Reeb Space. This distinction is significant, as exploiting multi-field topology ...
    • Coherent View-Dependent Streamlines for Understanding Blood Flow 

      Lawonn, Kai; Günther, Tobias; Preim, Bernhard (The Eurographics Association, 2014)
      The expressive visualization of (time-dependent) 3D blood flow along with the vessel wall is essential for understandingvascular diseases. However, the high complexity of the underlying flow data makes the explorationchallenging. ...
    • Color and Uncertainty: It is not always Black and White 

      Tak, Susanne; Toet, Alexander (The Eurographics Association, 2014)
      To fully comprehend the meaning and impact of visualized data it is crucial that users are able to perceive andcomprehend the inherent uncertainty of the data in a correct and intuitive way. Data uncertainty is ...
    • Visualizing Uncertainty in HARDI Tractography Using Superquadric Streamtubes 

      Wiens, Vitalis; Schlaffke, Lara; Schmidt-Wilcke, Tobias; Schultz, Thomas (The Eurographics Association, 2014)
