      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 

      Wu, Yingcai; Provan, Thomas; Wei, Furu; Liu, Shixia; Ma, Kwan-Liu (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Word clouds are proliferating on the Internet and have received much attention in visual analytics. Although word clouds can help users understand the major content of a document collection quickly, their ability to visually ...

    • A Shader Framework for Rapid Prototyping of GPU-Based Volume Rendering 

      Rieder, Christian; Palmer, Stephan; Link, Florian; Hahn, Horst K. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In this paper, we present a rapid prototyping framework for GPU-based volume rendering. Therefore, we propose a dynamic shader pipeline based on the SuperShader concept and illustrate the design decisions. Also, important ...

    • Stable Morse Decompositions for Piecewise Constant Vector Fields on Surfaces 

      Szymczak, Andrzej (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Numerical simulations and experimental observations are inherently imprecise. Therefore, most vector fields of interest in scientific visualization are known only up to an error. In such cases, some topological features, ...

    • Structural Decomposition Trees 

      Engel, Daniel; Rosenbaum, R.; Hamann, B.; Hagen, Hans (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Researchers and analysts in modern industrial and academic environments are faced with a daunting amount of multi-dimensional data. While there has been significant development in the areas of data mining and knowledge ...

    • Tablorer - An Interactive Tree Visualization System for Tablet PCs 

      Shin, HyunJu; Park, GwangHyun; Han, JungHyun (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      A variety of mobile devices are available today, but there is no dominant tree visualization system in the devices. This paper proposes Tablorer, a novel interactive tree visualization system for medium-sized mobile devices, ...

    • Temporal Visualization of Boundary-based Geo-information Using Radial Projection 

      Drocourt, Y.; Borgo, Rita; Scharrer, K.; Murray, T.; Bevan, S. I.; Chen, M. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      This work is concerned with a design study by an interdisciplinary team on visualizing a 10-year record of seasonal and inter-annual changes in frontal position (advance/retreat) of nearly 200 marine terminating glaciers ...

    • Topological Features in 2D Symmetric Higher-Order Tensor Fields 

      Schultz, Thomas (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      The topological structure of scalar, vector, and second-order tensor fields provides an important mathematical basis for data analysis and visualization. In this paper, we extend this framework towards higher-order tensors. ...
