    • Superquadric Tensor Glyphs 

      Kindlmann, Gordon (The Eurographics Association, 2004)
      Tensor field visualization is a challenging task due in part to the multi-variate nature of individual tensor samples. Glyphs convey tensor variables by mapping the tensor eigenvectors and eigenvalues to the orientation ...
    • Interaction Spaces in Data and Information Visualization 

      Ward, M.; Yang, J. (The Eurographics Association, 2004)
      User interaction plays an integral part in the effective visualization of data and information. Typical interaction operations include navigation, selection, and distortion. A problem that can occur when these operations ...
    • Visual Component Analysis 

      Müller, Wolfgang; Alexa, Marc (The Eurographics Association, 2004)
      We propose to integrate information visualization techniques with factor analysis. Specifically, a principal direction derived from a principal component analysis (PCA) of the data is displayed together with the data in a ...

      This paper addresses the issue of how information visualization techniques can be used to assist full-text search in electronic documents. Our approach supports multiple term queries with interactive treemaps. We use a ...
    • Accuracy Evaluation of Different Centerline Approximations of Blood Vessels 

      Cruz, A. La (The Eurographics Association, 2004)
      Accurate determination of the vessel axis is a prerequisite for automated visualization and quantification of artery diseases. This paper presents an evaluation of different methods for approximating the centerline of the ...
    • Case Study: Visualization of annotated DNA sequences 

      Peeters, Tim; Fiers, Mark; Wetering, Huub van de; Nap, Jan-Peter; Wijk, Jarke J. van (The Eurographics Association, 2004)
      DNA sequences and their annotations form ever expanding data sets. Proper explorations of such data sets require new tools for visualization and analysis. In this case study, we have defined the requirements for a visualization ...
    • Visualization For Public-Resource Climate Modeling 

      Stainforth, D.A.; Frame, D.; Walton, J.P.R.B. (The Eurographics Association, 2004)
      Climateprediction.net aims to harness the spare CPU cycles of a million individual users PCs to run a massive ensemble of climate simulations using an up-to-date, full-scale 3D atmosphere-ocean climate model. Although it ...
    • Visualising Organisms with Hydraulic Body Parts: A Case Study in Integrating Simulation and Visualisation Models 

      Breiner, T.; Dörner, R.; Seiler, C.; Gudo, M. (The Eurographics Association, 2004)
      The physical structure of organisms can be modelled as a set of coupled hydraulic entities. The hydropneumatic biosimulation is a methodology that is able to simulate the behavior (like movements) of such organisms on the ...
    • Case Study: Visual Analysis of Complex, Time-Dependent Simulation Results of a Diesel Exhaust System 

      Doleisch, Helmut; Mayer, Michael; Gasser, Martin; Wanker, Roland; Hauser, Helwig (The Eurographics Association, 2004)
      In previous work we have presented visualization techniques that provide engineers with a high degree of interactivity and flexibility for analyzing large, time-dependent, and high-dimensional data sets resulting from CFD ...
    • Texture-Based Flow Visualization on Isosurfaces from Computational Fluid Dynamics 

      Laramee, Robert S.; Schneider, Jürgen; Hauser, Helwig (The Eurographics Association, 2004)
      Isosurfacing, by itself, is a common visualization technique for investigating 3D vector fields. Applying texturebased flow visualization techniques to isosurfaces provides engineers with even more insight into the ...
    • Visual Triangulation of Network-Based Phylogenetic Trees 

      Brandes, U.; Dwyer, T.; Schreiber, F. (The Eurographics Association, 2004)
      Phylogenetic trees are built by examining differences in the biological traits of a set of species. An example of such a trait is a biological network such as a metabolic pathway, common to all species but with subtle ...
    • Graph Drawing by Subspace Optimization 

      Koren, Yehuda (The Eurographics Association, 2004)
      We show a novel approach for accelerating the computation of graph drawing algorithms. The method is based on the notion that we can find a subspace with a relatively low dimensionality that captures the "nice" layouts of ...
    • Shape-Embedded-Histograms for Visual Data Mining 

      Amir, Amihood; Kashi, Reuven; Keim, Daniel A.; Netanyahu, Nathan S.; Wawryniuk, Markus (The Eurographics Association, 2004)

    • TimeHistograms for Large, Time-Dependent Data 

      Kosara, Robert; Bendix, Fabian; Hauser, Helwig (The Eurographics Association, 2004)
      Histograms are a very useful tool for data analysis, because they show the distribution of values over a data dimension. Many data sets in engineering (like computational fluid dynamics, CFD), however, are time-dependent. ...
