      Wei, Tzu-Hsuan; Lee, Teng-Yok; Shen, Han-Wei (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      While isosurfaces have been widely used for scalar data visualization, it is often difficult to determine if the selected isosurfaces for visualization are sufficient to represent the entire scalar field. In this paper, ...
    • Constructing Isosurfaces with Sharp Edges and Corners using Cube Merging 

      Bhattacharya, Arindam; Wenger, Rephael (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      A number of papers present algorithms to construct isosurfaces with sharp edges and corners from hermite data, i.e. the exact surface normals at the exact intersection of the surface and grid edges. We discuss some fundamental ...
    • Maximum Entropy Summary Trees 

      Karloff, Howard; Shirley, Kenneth E. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Given a very large, node-weighted, rooted tree on, say, n nodes, if one has only enough space to display a knode summary of the tree, what is the most informative way to draw the tree? We define a type of weighted tree ...
    • Preface and Table of Contents 

      B. Preim, P. Rheingans, and H. Theisel (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    • Continuous Representation of Projected Attribute Spaces of Multifields over Any Spatial Sampling 

      Molchanov, Vladimir; Fofonov, Alexey; Linsen, Lars (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      For the visual analysis of multidimensional data, dimension reduction methods are commonly used to project to a lower-dimensional visual space. In the context of multifields, i.e., volume data with a multidimensional ...
    • Visualizing Interchange Patterns in Massive Movement Data 

      Zeng, Wei; Fu, Chi-Wing; Arisona, Stefan Müller; Qu, Huamin (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Massive amount of movement data, such as daily trips made by millions of passengers in a city, are widely available nowadays. They are a highly valuable means not only for unveiling human mobility patterns, but also for ...
    • Streamlines for Illustrative Real-Time Rendering 

      Lawonn, Kai; Moench, Tobias; Preim, Bernhard (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Line drawing techniques are important methods to illustrate shapes. Existing feature line methods, e.g., suggestive contours, apparent ridges, or photic extremum lines, solely determine salient regions and illustrate them ...
    • User-driven Feature Space Transformation

      Interactive visualization systems for exploring and manipulating high-dimensional feature spaces have experienced a substantial progress in the last few years. State-of-art methods rely on solid mathematical and computational ...
    • Spatially Efficient Design of Annotated Metro Maps 

      Wu, Hsiang-Yun; Takahashi, Shigeo; Hirono, Daichi; Arikawa, Masatoshi; Lin, Chun-Cheng; Yen, Hsu-Chun (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Annotating metro maps with thumbnail photographs is a commonly used technique for guiding travelers. However, conventional methods usually suffer from small labeling space around the metro stations, especially when they ...
    • AOI Rivers for Visualizing Dynamic Eye Gaze Frequencies 

      Burch, Michael; Kull, Andreas; Weiskopf, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      It is difficult to explore and analyze eye gaze trajectories for commonly applied visual task solution strategies because such data shows complex spatio-temporal structure. In particular, the traditional eye gaze plots of ...
    • Vector Field k-Means: Clustering Trajectories by Fitting Multiple Vector Fields 

      Ferreira, Nivan; Klosowski, James T.; Scheidegger, Carlos E.; Silva, Cláudio T. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
