    • Localized Flow Analysis of 2D and 3D Vector Fields 

      Wiebel, Alexander; Garth, Christoph; Scheuermann, Gerik (The Eurographics Association, 2005)
      In this paper we present an approach to the analysis of the contribution of a small subregion in a dataset to the global flow. To this purpose, we subtract the potential flow that is induced by the boundary of the sub-domain ...

    • Mail Explorer - Spatial and Temporal Exploration of Electronic Mail

      In today s world, e-mail has become one of the most important means of communication in business and private lives due to its efficiency. However, the problems start as soon as mail volumes go beyond the scope of human ...

    • MoireTrees: Visualization and Interaction for Multi-Hierarchical Data 

      Mohammadi-Aragh, Mahnas Jean; Jankun-Kelly, T. J. (The Eurographics Association, 2005)
      Visualizing hierarchical data is one of the core areas of information visualization. Most of these techniques focus on single hierarchies hierarchies with a single root element and a single path to each element. In contrast, ...

    • Non-manifold Mesh Extraction from Time-varying Segmented Volumes used for Modeling a Human Heart 

      Bertram, Martin; Reis, Gerd; Lengen, Rolf H. van; Köhn, Sascha; Hagen, Hans (The Eurographics Association, 2005)
      We present a new algorithm extracting and fairing surfaces from segmented volumes composed of multiple materials. In a first pass, the material boundaries in the volume are smoothed considering signed distance functions ...

    • Pointillist and Glyph-based Visualization of Nanoparticles in Formation 

      Saunders, P. Coleman; Interrante, Victoria; Garrick, Sean C. (The Eurographics Association, 2005)
      In this paper we offer new, texture-based methods for the visualization of multivariate data. These methods aim to more effectively convey the results of calculations simulating the formation of nanoparticles in turbulent ...

    • Real-Time Advection and Volumetric Illumination for the Visualization of 3D Unsteady Flow 

      Weiskopf, Daniel; Schafhitzel, Tobias; Ertl, Thomas (The Eurographics Association, 2005)
      This paper presents an interactive technique for the dense texture-based visualization of unsteady 3D flow, taking into account issues of computational efficiency and visual perception. High efficiency is achieved by a ...

    • Scalable, Robust Visualization of Very Large Trees 

      Beermann, Dale; Munzner, Tamara; Humphreys, Greg (The Eurographics Association, 2005)
      The TreeJuxtaposer system [MGT*03] allowed visual comparison of large trees with guaranteed visibility of landmarks and Focus+Context navigation. While that system allowed exploration and comparison of larger datasets than ...

    • A Simple and Novel Seed-Set Finding Approach for Iso-Surface Extraction 

      Hung, Chiang-Han; Yang, Chuan-kai (The Eurographics Association, 2005)
      Iso-surface extraction is one of the most important approaches for volume rendering, and iso-contouring is one of the most effective methods for iso-surface extraction. Unlike most other methods having their search domain ...

    • Spatialized Transfer Functions 

      Roettger, Stefan; Bauer, Michael; Stamminger, Marc (The Eurographics Association, 2005)
      Multi-dimensional transfer functions are an efficient way to visualize features in scalar volume data produced by CT or MRI scanners. However, the optimal transfer function is difficult to find in general. We present an ...

    • Spline-Based Gradient Filters For High-Quality Refraction Computations in Discrete Datasets 

      Li, Shengying; Mueller, Klaus (The Eurographics Association, 2005)
      Based on the finding that refraction imposes significantly higher demands onto gradient filters than illumination and shading, we evaluate the family of spline filters as a good alternative to the cubic filters, which so ...

    • Tiled Parallel Coordinates for the Visualization of Time-Varying Multichannel EEG Data 

      Caat, Michael ten; Maurits, N. M.; Roerdink, J. B. T. M. (The Eurographics Association, 2005)
      The field of visualization assists data interpretation in many areas, but some types of data are not manageable by existing visualization techniques. This holds in particular for time-varying multichannel EEG data. No ...

    • Transfer Functions for Imaging Spectroscopy Data using Principal Component Analysis 

      Broersen, Alexander; Liere, Robert van (The Eurographics Association, 2005)
      In this paper we present a new application of the principal component analysis (PCA) to generate multidimensional transfer functions. These transfer functions are needed in the volumetric visualization of spectral data to ...

    • Vector Field Analysis and Visualization through Variational Clustering 

      McKenzie, Alexander; Lombeyda, Santiago V.; Desbrun, Mathieu (The Eurographics Association, 2005)
      Scientific computing is an increasingly crucial component of research in various disciplines. Despite its potential, exploration of the results is an often laborious task, owing to excessively large and verbose datasets ...
