      Sutton, Philip M.; Hansen, Charles D.; Shen, Han-Wei; Schikore, Dan (The Eurographics Association, 2000)
      Isosurface extraction is an important and useful visualization method. Over the past ten years, the field has seen numerous isosurface techniques published, leaving the user in a quandary about which one should be used. ...
    • WWW-based Visualization of the Real Time Run of a Space Weather Forecasting Model 

      Maurtis, Sergei; McAllister, Jeff; Watkins, Brenton (The Eurographics Association, 2000)
      As use of earth-orbiting space technology increases, so does the need to understand and forecast the space weather. The University of Alaska Fairbanks Eulerian Parallel Polar Ionosphere Model (UAF EPPIM) is a first principles ...

    • AlVis - An Aluminium-Foam Visualization and Investigation Tool 

      König, Andreas H.; Doleisch, Helmut; Kottar, Andreas; Kriszt, Brigitte; Gröller, Eduard (The Eurographics Association, 2000)
      In recent years there has been an increased interest in metal foams in the field of material science. The stress absorbing potential is one of the most interesting properties for the application of aluminium foam (e.g. car ...
    • ViSSh: A Data Visualisation Spreadsheet 

      Nunez, Fabian; Blake, Edwin (The Eurographics Association, 2000)
      We describe a data visualisation system which uses spreadsheets as its user interface metaphor. Similar systems implemented in the past were hampered by the contradiction between an imperative formula language and the ...
    • Design of Visualizations for Urban Modeling 

      Pinnel, L. Denise; Dockrey, Matthew; Brush, A.J. Bernheim; Borning, Alan (The Eurographics Association, 2000)
      Urban planning experts often use computer models to help evaluate alternative land use policies, particularly as they interact with transportation and environmental decisions. The greatly increased data volume provided by ...
    • SMARTLINK: An Agent for Supporting Dataflow Application Construction 

      Telea, Alexandru; Wijk, Jarke J. van (The Eurographics Association, 2000)
      Visual programmable dataflow systems are an effective way to build a large class of visualization applications from existing software modules. However, the appeal of dataflow systems is often decreased as their users have ...
    • A Framework for Interactive Hardware Accelerated Remote 3D-Visualization 

      Engel, Klaus; Sommer, Ove; Ertl, Thomas (The Eurographics Association, 2000)
      In this paper we present a framework that provides remote control to Open Inventor or Cosmo3D based visualization applications. A visualization server distributes a visualization session to Java based clients by transmitting ...
    • Appearance-Based Virtual-View Generation for Fly Through in a Real Dynamic Scene 

      Baba, Shigeyuki; Saito, Hideo; Vedula, Sundar; Cheung, Kong Man; Kanade, Takeo (The Eurographics Association, 2000)
      We present appearance-based virtual view generation which allows viewers to fly through a real dynamic scene. The scene is captured by synchronized multiple cameras. Arbitrary views are generated by interpolating two ...
    • Hybrid Model for Vascular Tree Structures 

      Puig, Anna; Tost, Dani; Navazo, Isabel (The Eurographics Association, 2000)
      This paper proposes a new representation scheme of the cerebral blood vessels. This model provides information on the semantics of the vascular structure: the topological relationships between vessels and the labeling of ...
    • Integrated Multiresolution Geometry and Texture Models for Terrain Visualization 

      Baumann, Konstantin; Döllner, Jürgen; Hinrichs, Klaus (The Eurographics Association, 2000)
      In this paper, an approach for integrating multiresolution representations of terrain geometry and terrain texture data is presented. A terrain is modeled by a regular grid, which can be partially refined by local TINs in ...
    • Variational Approach to Vector Field Decomposition 

      Polthier, Konrad; Preuß, Eike (The Eurographics Association, 2000)
      For the feature analysis of vector fields we decompose a given vector field into three components: a divergence-free, a rotation-free, and a harmonic vector field. This Hodge-type decomposition splits a vector field using ...
    • Direct Volume Rendering from Photographic Data 

      Ebert, David; McClanahan, Tim; Rheingans, Penny; Yoo, Terry (The Eurographics Association, 2000)
      Direct volume rendering from photographic volume data has the potential to create realistic images of internal volume structure, as well as the structure of boundaries within the volume. While possession of the photographic ...
