    • Contextual Visualization of Actor Status in Social Networks 

      Brandes, Ulrik; Wagner, Dorothea (The Eurographics Association, 2000)
      We propose a novel information visualization approach for an analytical method applied in the social sciences. In social network analysis, social structures are formally represented as graphs, and structural properties of ...

      Schussman, Shirley; Bertram, Martin; Hamann, Bernd; Joy, Kenneth I. (The Eurographics Association, 2000)
      Multiresolution representation of high-dimensional scattered data is a fundamental problem in scientific visualization. This paper introduces a data hierarchy of Voronoi diagrams as a versatile solution. Given an arbitrary ...
    • 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 ...
    • 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 ...
    • 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 ...
    • DAG Drawing from an Information Visualization Perspective 

      Melancon, G.; Herman, I. (The Eurographics Association, 2000)
      When dealing with a graph, any visualization strategy must rely on a layout procedure at least to initiate the process. Because the visualization process evolves within an interactive environment the choice of this layout ...
    • Fast Visualization of Special Relativistic Effects on Geometry and Illumination 

      Weiskopf, Daniel (The Eurographics Association, 2000)
      This paper describes a novel rendering technique for the special relativistic visualization of the geometry and illumination of fast moving objects. The physical basis consists of the relativistic aberration of light, the ...
    • 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 ...
    • Drawing Relational Schemas 

      Battista, Giuseppe Di; Didimo, Walter; Patrignani, Maurizio; Pizzonia, Maurizio (The Eurographics Association, 2000)
      A wide number of practical applications would benefit from automatically generated graphical representations of relational schemas, in which tables are represented by boxes, and table attributes correspond to distinct ...
    • 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 ...
    • 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 ...
    • 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 ...
    • Hardware Accelerated Wavelet Transformations 

      Hopf, Matthias; Ertl, Thomas (The Eurographics Association, 2000)
      Wavelets and related multiscale representations are important means for edge detection and processing as well as for segmentation and registration. Due to the computational complexity of these approaches no interactive ...
    • 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 ...
    • Case Study: Resource Steering in a Visualization System 

      Chi, Ed H.; Riedl, John T. (The Eurographics Association, 2000)
      Visual computational steering environments extend traditional visualization environments by enabling the user to interactively steer the computations applied to the data. In this paper, we develop a new type of computational ...
    • A Case Study of Isosurface Extraction Algorithm Performance 

      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. ...
