      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, ...
    • High-Quality Volume Rendering with Resampling in the Frequency Domain 

      Artner, Martin; Möller, Torsten; Viola, Ivan; Gröller, Meister E. (The Eurographics Association, 2005)
      This work introduces a volume rendering technique that is conceptually based on the shear-warp factorization. We propose to perform the shear transformation in the frequency domain. Unlike the standard shear-warp algorithm, ...

      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 ...

      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 ...
    • 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 ...
    • Dynamically Modelling Interaction 

      May, Jon (The Eurographics Association, 2005)
      Technological advances are increasing the use of dynamic or changing displays, in many forms of interface. The increasing amount of information held on the Internet and in private government and commercial databases also ...
    • Visualization for Validation and Improvement of Three-dimensional Segmentation Algorithms 

      Weber, Gunther H.; Hendriks, Cris L. Luengo; Keränen, Soile V. E.; Dillard, Scott E.; Ju, Derek Y.; Sudar, Damir; Hamann, Bernd (The Eurographics Association, 2005)
      The Berkeley DrosophilaTranscription Network Project (BDTNP) is developing a suite of methods that will allow a quantitative description and analysis of three dimensional (3D) gene expression patterns in an animal with ...
    • GVis: A Scalable Visualization Framework for Genomic Data 

      Hong, Jin; Jeong, Dong Hyun; Shaw, Chris D; Ribarsky, William; Borodovsky, Mark; Song, Chang (The Eurographics Association, 2005)
      This paper describes a framework we have developed for the visual analysis of large-scale phylogeny hierarchies populated with the genomic data of various organisms. This framework allows the user to quickly browse the ...
    • Interactive rendering of massive terrains on PC clusters 

      Gouranton, V.; Madougou, Souley; Melin, Emmanuel; Nortet, Cyril (The Eurographics Association, 2005)
      We describe a parallel framework for interactive smooth rendering of massive terrains. We define a parallelization scheme for level of detail algorithms in cluster-based environments. The scheme relies on modern PC clusters ...
    • 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 ...
    • Galilean Invariant Extraction and Iconic Representation of Vortex Core Lines 

      Sahner, Jan; Weinkauf, Tino; Hege, Hans-Christian (The Eurographics Association, 2005)
      While vortex region quantities are Galilean invariant, most methods for extracting vortex cores depend on the frame of reference. We present an approach to extracting vortex core lines independently of the frame of reference ...
    • The i-Disc - A Tool To Visualize and Explore Topic Maps 

      Hofmann, Tobias; Wendler, Hendrik; Froehlich, Bernd (The Eurographics Association, 2005)
      We present the i-Disc, a tool to interactively visualize and explore medium sized topic maps. Topic maps contain two basic structures: the topic hierarchy and the associations between topics. Our system presents the topic ...
    • Illustrative Context-Preserving Volume Rendering 

      Bruckner, Stefan; Grimm, Sören; Kanitsar, Armin; Gröller, M. Eduard (The Eurographics Association, 2005)
      In volume rendering it is very difficult to simultaneously visualize interior and exterior structures while preserving clear shape cues. Very transparent transfer functions produce cluttered images with many overlapping ...
