      Zwan, Matthew van der; Lueks, Wouter; Bekker, Henk; Isenberg, Tobias (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Molecular systems may be visualized with various degrees of structural abstraction, support of spatial perception, and 'illustrativeness.' In this work we propose and realize methods to create seamless transformations that ...

    • ImPrEd: An Improved Force-Directed Algorithm that Prevents Nodes from Crossing Edges

      We describe a simulation-time random sampling of a large-scale particle simulation, the RoadRunner Universe MC3 cosmological simulation, for interactive post-analysis and visualization. Simulation data generation rates ...

    • Interactive Exploration of Protein Cavities 

      Krone, M.; Falk, M.; Rehm, S.; Pleiss, J.; Ertl, T. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      We present a novel application for the interactive exploration of cavities within proteins in dynamic data sets. Inside a protein, cavities can often be found close to the active center. Therefore, when analyzing a molecular ...

    • Interactive Visual Analysis of Temporal Cluster Structures 

      Turkay, Cagatay; Parulek, J.; Reuter, N.; Hauser, Helwig (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Cluster analysis is a useful method which reveals underlying structures and relations of items after grouping them into clusters. In the case of temporal data, clusters are defined over time intervals where they usually ...

    • Lagrangian Coherent Structures with Guaranteed Material Separation 

      Germer, Tobias; Otto, Mathias; Peikert, R.; Theisel, H. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Given an unsteady flow field, one common way to compute Lagrangian Coherent Structures (LCS) is to extract extremal structures of the Finite Time Lyapunov Exponent (FTLE). Experience has shown that the resulting structures ...

    • PaperVis: Literature Review Made Easy 

      Chou, Jia -Kai; Yang, C. -K. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Reviewing literatures for a certain research field is always important for academics. One could use Google-like information seeking tools, but oftentimes he/she would end up obtaining too many possibly related papers, as ...

    • Pathway Preserving Representation of Metabolic Networks 

      Lambert, Antoine; Dubois, J.; Bourqui, Romain (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Improvements in biological data acquisition and genomes sequencing now allow to reconstruct entire metabolic networks of many living organisms. The size and complexity of these networks prohibit manual drawing and thereby ...

    • Perceptual Evaluation of Ghosted View Techniques for the Exploration of Vascular Structures and Embedded Flow 

      Baer, Alexandra; Gasteiger, Rocco; Cunningham, Douglas; Preim, Bernhard (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      This paper presents three controlled perceptual studies investigating the visualization of the cerebral aneurysm anatomy with embedded flow visualization. We evaluate and compare the common semitransparent visualization ...

    • Piecewise Laplacian-based Projection for Interactive Data Exploration and Organization 

      Paulovich, Fernando V.; Eler, D. M.; Poco, J.; Botha, Charl P.; Minghim, R.; Nonato, L. G. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Multidimensional projection has emerged as an important visualization tool in applications involving the visual analysis of high-dimensional data. However, high precision projection methods are either computationally ...

    • Probabilistic Marching Cubes 

      Pöthkow, Kai; Weber, Britta; Hege, Hans-Christian (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In this paper we revisit the computation and visualization of equivalents to isocontours in uncertain scalar fields. We model uncertainty by discrete random fields and, in contrast to previous methods, also take arbitrary ...

    • Progressive Splatting of Continuous Scatterplots and Parallel Coordinates 

      Heinrich, Julian; Bachthaler, S.; Weiskopf, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Continuous scatterplots and parallel coordinates are used to visualize multivariate data defined on a continuous domain. With the existing techniques, rendering such plots becomes prohibitively slow, especially for large ...

    • Prostate Cancer Visualization from MR Imagery and MR Spectroscopy 

      Marino, Joseph; Kaufman, Arie (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Prostate cancer is one of the most prevalent cancers among males, and the use of magnetic resonance imaging (MRI) has been suggested for its detection. A framework is presented for scoring and visualizing various MR data ...

    • Semantic-Preserving Word Clouds by Seam Carving
