      We present a flow visualization technique based on rendering geometry in a dense, uniform distribution. Flow is integrated using particle advection. By adopting ideas from texture-based techniques and taking advantage of ...
    • Discovering High-level Parameters for Visualization Design 

      Bhagavatula, Srinivas; Rheingans, Penny; Jardins, Marie des (The Eurographics Association, 2005)
      In most graphics and visualization applications, the effects of the mapping parameters on the output domain are multidimensional, non-linear and discontinuous. The complexity of such mapping often makes it difficult for a ...
    • 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 ...
    • Extending and Simplifying Transfer Function Design in Medical Volume Rendering Using Local Histograms 

      Lundström, Claes; Ljung, Patric; Ynnerman, Anders (The Eurographics Association, 2005)
      Direct Volume Rendering (DVR) is known to be of diagnostic value in the analysis of medical data sets. However, its deployment in everyday clinical use has so far been limited. Two major challenges are that the current ...
    • 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 ...
    • 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 ...
    • Hardware-Accelerated Glyphs for Mono- and Dipoles in Molecular Dynamics Visualization 

      Reina, Guido; Ertl, Thomas (The Eurographics Association, 2005)
      We present a novel visualization method for mono- and dipolar molecular simulations from thermodynamics that takes advantage of modern graphics hardware to interactively render specifically tailored glyphs. Our approach ...
    • High-Quality Rendering of Compressed Volume Data Formats 

      Fout, Nathaniel; Akiba, Hiroshi; Ma, Kwan-Liu; Lefohn, Aaron E.; Kniss, Joe (The Eurographics Association, 2005)
      Rendering directly from packed or compressed volume data formats using graphics hardware has advantages in terms of memory consumption and bandwidth, but results in lower-quality images due to the prohibitive cost of ...
    • 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, ...
    • 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 ...
