    • Retailoring Box Splines to Lattices for Highly Isotropic Volume Representations 

      Csébfalvi, Balázs; Rácz, Gergely (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      3D box splines are defined by convolving a 1D box function with itself along different directions. In volume visualization, box splines are mainly used as reconstruction kernels that are easy to adapt to various sampling ...

      We present an Aortic Vortex Classification (AVOCLA) that allows to classify vortices in the human aorta semi-automatically. Current medical studies assume a strong relation between cardiovascular diseases and blood flow ...
    • Similarity Voting based Viewpoint Selection for Volumes 

      Tao, Yubo; Wang, Qirui; Chen, Wei; Wu, Yingcai; Lin, Hai (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Previous viewpoint selection methods in volume visualization are generally based on some deterministic measures of viewpoint quality. However, they may not express the familiarity and aesthetic sense of users for features ...
    • Source Inversion by Forward Integration in Inertial Flows 

      Günther, Tobias; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Inertial particles are finite-sized objects traveling with a certain velocity that differs from the underlying carrying flow, i.e., they are mass-dependent and subject to inertia. Their backward integration is in practice ...
    • Space-Time Bifurcation Lines for Extraction of 2D Lagrangian Coherent Structures 

      Machado, Gustavo Mello; Boblest, Sebastian; Ertl, Thomas; Sadlo, Filip (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a novel and efficient technique to extract Lagrangian coherent structures in two-dimensional time-dependent vector fields. We show that this can be achieved by employing bifurcation line extraction in the ...
    • TextDNA: Visualizing Word Usage with Configurable Colorfields 

      Szafir, Danielle Albers; Stuffer, Deidre; Sohail, Yusef; Gleicher, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Patterns of words used in different text collections can characterize interesting properties of a corpus. However, these patterns are challenging to explore as they often involve complex relationships across many words and ...
    • There is More to Streamgraphs than Movies: Better Aesthetics via Ordering and Lassoing 

      Bartolomeo, Marco Di; Hu, Yifan (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Streamgraphs were popularized in 2008 when The New York Times used them to visualize box office revenues for 7500 movies over 21 years. The aesthetics of a streamgraph is affected by three components: the ordering of the ...
    • Time-Series Plots Integrated in Parallel-Coordinates Displays 

      Gruendl, Henning; Riehmann, Patrick; Pausch, Yves; Froehlich, Bernd (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a natural extension of two-dimensional parallel-coordinates plots for revealing relationships in time-dependent multi-attribute data by building on the idea that time can be considered as the third dimension. A ...
