    • RBF Volume Ray Casting on Multicore and Manycore CPUs 

      Knoll, Aaron; Wald, Ingo; Navratil, Paul; Bowen, Anne; Reda, Khairi; Papka, Mike E.; Gaither, Kelly (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Modern supercomputers enable increasingly large N-body simulations using unstructured point data. The structures implied by these points can be reconstructed implicitly. Direct volume rendering of radial basis function ...

    • Semi-Automatic Editing of Graphs with Customized Layouts 

      Gladisch, Stefan; Schumann, Heidrun; Ernst, Mathias; Füllen, Georg; Tominski, Christian (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Usually visualization is applied to gain insight into data. Yet consuming the data in form of visual representation is not always enough. Instead, users need to edit the data, preferably through the same means used to ...

    • Sets of Globally Optimal Stream Surfaces for Flow Visualization 

      Schulze, Maik; Esturo, Janick Martinez; Günther, Tobias; Rössl, Christian; Seidel, Hans-Peter; Weinkauf, Tino; Theisel, Holger (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Stream surfaces are a well-studied and widely used tool for the visualization of 3D flow fields. Usually, stream surface seeding is carried out manually in time-consuming trial and error procedures. Only recently automatic ...

    • SimilarityExplorer: A Visual Inter-Comparison Tool for Multifaceted Climate Data 

      Poco, Jorge; Dasgupta, Aritra; Wei, Yaxing; Hargrove, William; Schwalm, Christopher; Cook, Robert; Bertini, Enrico; Silva, Claudio (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Inter-comparison and similarity analysis to gauge consensus among multiple simulation models is a critical visualization problem for understanding climate change patterns. Climate models, specifically, Terrestrial Biosphere ...

    • Sparse Representation and Visualization for Direct Numerical Simulation of Premixed Combustion 

      Oster, Timo; Lehmann, Dirk J.; Frau, Gordon; Theisel, Holger; Thévenin, Dominique (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Direct Numerical Simulations of premixed combustion produce terabytes of raw data, which are prohibitively large to be stored, and have to be analyzed and visualized. A simultaneous and integrated treatment of data storage, ...

    • Stability of Dissipation Elements: A Case Study in Combustion 

      Gyulassy, Attila; Bremer, Peer-Timo; Grout, Ray; Kolla, Hemanth; Chen, Jacqueline; Pascucci, Valerio (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Recently, dissipation elements have been gaining popularity as a mechanism for measurement of fundamental properties of turbulent flow, such as turbulence length scales and zonal partitioning. Dissipation elements segment ...

    • Towards an Unbiased Comparison of CC, BCC, and FCC Lattices in Terms of Prealiasing 

      Vad, Viktor; Csébfalvi, Balázs; Rautek, Peter; Gröller, Eduard (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In the literature on optimal regular volume sampling, the Body-Centered Cubic (BCC) lattice has been proven to be optimal for sampling spherically band-limited signals above the Nyquist limit. On the other hand, if the ...

    • Visual Analysis of Sets of Heterogeneous Matrices Using Projection-Based Distance Functions and Semantic Zoom 

      Behrisch, Michael; Davey, James; Fischer, Fabian; Thonnard, Olivier; Schreck, Tobias; Keim, Daniel; Kohlhammer, Jörn (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Matrix visualization is an established technique in the analysis of relational data. It is applicable to large, dense networks, where node-link representations may not be effective. Recently, domains have emerged in which ...

    • Visual Analysis of Time-Series Similarities for Anomaly Detection in Sensor Networks 

      Steiger, Martin; Bernard, Jürgen; Mittelstädt, Sebastian; Lücke-Tieke, Hendrik; Keim, Daniel; May, Thorsten; Kohlhammer, Jörn (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a system to analyze time-series data in sensor networks. Our approach supports exploratory tasks for the comparison of univariate, geo-referenced sensor data, in particular for anomaly detection. We split the ...

    • Visual Multiplexing 

      Chen, Min; Walton, Simon; Berger, Kai; Thiyagalingam, Jeyan; Duffy, Brian; Fang, Hui; Holloway, Cameron; Trefethen, Anne E. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      The majority of display devices used in visualization are 2D displays. Inevitably, it is often necessary to overlay one piece of visual information on top of another, especially in applications such as multi-field visualization ...

    • Visual-interactive Exploration of Interesting Multivariate Relations in Mixed Research Data Sets 

      Bernard, Jürgen; Steiger, Martin; Widmer, Sven; Lücke-Tieke, Hendrik; May, Thorsten; Kohlhammer, Jörn (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      The analysis of research data plays a key role in data-driven areas of science. Varieties of mixed research data sets exist and scientists aim to derive or validate hypotheses to find undiscovered knowledge. Many analysis ...

    • Visualization of Medicine Prescription Behavior 

      Corput, Paul van der; Arends, Johan; Wijk, Jarke J. van (The Eurographics Association and John Wiley and Sons Ltd., 2014)
