    • Improved Sparse Seeding for 3D Electrostatic Field Lines 

      Scharnowski, Katrin; Boblest, Sebastian; Ertl, Thomas (The Eurographics Association, 2015)
      We present an improved seeding strategy for sparse visualization of electrostatic fields. By analyzing the curvature of the field lines, we extract points of extremal field strength between charges of different sign and ...
    • Interaction with Uncertainty in Visualisations 

      Sarkar, Advait; Blackwell, Alan F.; Jamnik, Mateja; Spott, Martin (The Eurographics Association, 2015)
      In recent years, a number of algorithms have been developed which provide fast approximate computations on large datasets. There is considerable interest in exploiting these techniques to render interactive visualisations ...
    • OceanPaths: Visualizing Multivariate Oceanography Data 

      Nobre, Carolina; Lex, Alexander (The Eurographics Association, 2015)
      Geographical datasets are ubiquitous in oceanography. While map-based visualizations are useful for many different domains, they can suffer from cluttering and overplotting issues when used for multivariate data sets. As ...
    • PoPI: Glyph Designs for Collaborative Filtering on Interactive Tabletops 

      Charleer, Sven; Klerkx, Joris; Duval, Erik (The Eurographics Association, 2015)
      Filtering data on a visualization can be a challenge when multiple people work on a shared visualization, for instance on an interactive tabletop. Visualizations can present data that satisfy the union of all user filters, ...
    • A Quality-Preserving Cartesian to Body-Centered Cubic Downsampling Transform 

      Alim, Usman R.; Oliveira, Thiago Valentin de (The Eurographics Association, 2015)
      The body-centered cubic lattice is the optimal sampling lattice in three dimensions. However, most volumetric datasets are acquired on the well-known Cartesian cubic lattice. In order to leverage the approximation capabilities ...
    • State of the Art in Mobile Volume Rendering on iOS Devices 

      Schiewe, Alexander; Anstoots, Mario; Krüger, Jens (The Eurographics Association, 2015)
      The ubiquity of ever-increasing computing power with mobile devices has put last generation desktop-grade hardware in everyone's palms. Mobile computing hardware is rapidly approaching today's desktop-grade hardware ...
    • Task Taxonomy for Cartograms 

      Nusrat, Sabrina; Kobourov, Stephen (The Eurographics Association, 2015)
      Cartograms are maps in which areas of geographic regions (countries, states) appear in proportion to some variable of interest (population, income). Despite the popularity of cartograms and the large number of cartogram ...
