    • Improving Angular Resolution in Visualizations of Geographic Networks 

      Brandes, Ulrik; Shubina, Galina; Tamassia, Roberto (The Eurographics Association, 2000)
      In visualizations of large-scale transportation and communications networks, node coordinates are usually fixed to preserve the underlying geography, while links are represented as geodesics for simplicity. This often leads ...
    • 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 ...
    • Multiresolution Techniques for Interactive Texture-based Rendering of Arbitrarily Oriented Cutting Planes 

      LaMar, Eric; Duchaineau, Mark A.; Hamann, Bernd; Joy, Kenneth I. (The Eurographics Association, 2000)
      We present a multiresolution technique for interactive texture based rendering of arbitrarily oriented cutting planes for very large data sets. Thismethod uses an adaptive scheme that renders the data along a cutting plane ...
    • Progressive Volume Models for Rectilinear Data using Tetrahedral Coons Volumes 

      Holliday, David J.; Nielson, Gregory M. (The Eurographics Association, 2000)
      We present a new technique for modeling rectilinear volume data. The algorithm produces a trivariate model, F(x; y; z), which is piecewise defined over tetrahedra that fits the volume data to within a user specified ...
    • Skeleton Graph Generation for Feature Shape Description 

      Reinders, Freek; Jacobson, Melvin E.D.; Post, Frits H. (The Eurographics Association, 2000)
      An essential step in feature extraction is the calculation of attribute sets describing the characteristics of a feature. Often, attribute sets include the position, size, and orientation of the feature. These attributes ...
    • 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 ...
    • Squarified Treemaps 

      Bruls, Mark; Huizing, Kees; Wijk, Jarke J. van (The Eurographics Association, 2000)
      An extension to the treemap method for the visualization of hierarchical information, such as directory structures and organization structures, is presented. The standard treemap method often gives thin, elongated rectangles. ...
    • Towards visual matching as a way of transferring pre-operative surgery planning 

      Buck, Stijn De; Cleynenbreugel, Johan Van; Marchal, Guy; Suetens, Paul (The Eurographics Association, 2000)
      This paper presents a case study towards intra-operative visualization of pre-operative medical images and surgery planning information. We describe a two stage procedure to provide a surgeon with valuable information ...
    • 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 ...
    • Very Large Scale Visualization Methods for Astrophysical Data 

      Hanson, Andrew J.; Fu, Chi-Wing; Wernert, Eric A. (The Eurographics Association, 2000)
      We address the problem of interacting with scenes that contain a very large range of scales. Computer graphics environments normally deal with only a limited range of orders of magnitude before numerical error and other ...
    • 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 ...
    • 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 ...
