    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • Hierarchical Data Representations Based on Planar Voronoi Diagrams 

      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 ...

    • 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 ...

    • Dynamic Overview Techniques for Image Retrieval 

      Pu, Pearl; Pecenovic, Zoran (The Eurographics Association, 2000)
      One difficulty often overlooked in information retrieval systems is that search criteria themselves are often poorly defined. People describe their information needs in many different ways and frequently change their goals ...

    • 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 ...

    • 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 ...
