    • Particle Tracing in σ-Transformed Grids using Tetrahedral 6-Decomposition 

      Sadarjoen, Ari; Boer, Alex J. de; Post, Frits H.; Mynett, Arthur E. (The Eurographics Association, 1998)
      Particle tracing in curvilinear grids often employs decomposition of hexahedral cells into 5 tetrahedra. This method has shortcomings when applied to sigma-transformed grids, a grid type having strongly sheared cells, ...

    • Fast Generation of Multiresolution Surfaces from Contours 

      Schilling, Andreas; Klein, Reinhard (The Eurographics Association, 1998)
      Surface reconstruction from contours is an important problem especially in medical applications. Other uses include reconstruction from topographic data, or isosurface generation in general. The drawback of existing ...

    • Experiments on the Accuracy of Feature Extraction 

      Reinders, Freek; Spoelder, Hans J.W.; Post, Frits H. (The Eurographics Association, 1998)
      Feature extraction is an approach to visualization that ex- tracts important regions or objects of interest algorithmically from large data sets. In our feature extraction process, high-level attributes are cal- culated ...

    • Stereoscopic Volume Rendering 

      Hubbold, Roger J.; Hancock, David J.; Moore, Christopher J. (The Eurographics Association, 1998)
      In this paper we describe the extension of a parallel, distributed, direct volume renderer for use with a novel auto-stereoscopic display. We begin by brie y describing the target application of our research, radiation ...

    • Mirror, Mirror on the Wall, Who Has the Best Visualization of All?- A Reference Model for Visualization Quality 

      Haase, Helmut (The Eurographics Association, 1998)
      What is a 'good' visualization, one which leads to desired insights? How can we evaluate the quality of a scientific visualization or compare two visualizations (or visualization systems) to each other? In the following, ...

    • Visualization of Time-Dependent Velocity Fields by Texture Transport 

      Becker, Joachim; Rumpf, Martin (The Eurographics Association, 1998)
      Vector field visualization is an important topic in scientific visualization. The aim is to graphically represent field data in an intuitively understandable and precise way, which should be closely related to the physical ...

    • Three-Dimensional Visualization of Atomic Collision Cascades 

      Sroubek, Filip; Slavik, Pavel (The Eurographics Association, 1998)
      The paper describes a new approach to the visualization of atomic collision cascades and using the interaction with visualized data. The collision cascade is a physical phenomenon initiated by bombarding the surface of a ...

    • Particle Tracing on Sparse Grids 

      Teitzel, Christian; Grosso, Roberto; Ertl, Thomas (The Eurographics Association, 1998)
      These days sparse grids are of increasing interest in numerical simulations. Based upon hierarchical tensor product bases, the sparse grid approach is a very e cient one improving the ratio of invested storage and computing ...

    • Data Compression of Multiresolution Surfaces 

      Klein, Reinhard; Gumhold, Stefan (The Eurographics Association, 1998)
      In this paper we introduce a new compressed representation for multiresolution models (MRM) of triangulated surfaces of 3D-objects. Associated with the representation we present compression and decompression algorithms. ...

    • Adaptively Adjusting Marching Cubes Output to Fit A Trilinear Reconstruction Filter 

      Allamandri, Fabio; Cignoni, Paolo; Montani, Claudio; Scopigno, Roberto (The Eurographics Association, 1998)
      The paper focuses on the improvement of the quality of isosurfaces fitted on volume datasets with respect to standard MC solutions. The new solution presented improves the precision in the reconstruction process using an ...

    • Data-Dependent Surface Simplification 

      Frank, Karin; Lang, Ulrich (The Eurographics Association, 1998)
      In Scientific Visualization, surfaces have often attached data, e. g. cutting surfaces or isosurfaces in numerical simulations with multiple data components. These surfaces can be e. g. the output of a marching cubes ...

    • Where Weather Meets the Eye - A Case Study on a Wide Range of Meteorological Visualizations for Diverse Audiences 

      Haase, H.; Bock, M.; Hergenröther, E.; Knöpfle, C.; Koppert, H.-J.; Schröder, F.; Trembilski, A.; Weidenhausen, J. (Springer and The Eurographics Association, 1999)
      Sophisticated visualisation enables experts as well as lay persons to extract knowledge from complex data. This is particularly true for visualising the massive amounts of data involved in meteorological observations and ...

    • 2D Vector Field Visualization Using Furlike Texture 

      Khouas, Leila; Odet, Christophe; Friboulet, Denis (Springer and The Eurographics Association, 1999)
      This paper presents a new technique for 2D vector field visualization. Our approach is based on the use of a furlike texture. For this purpose, we have first developed a texture model that allows two dimensional synthesis ...

    • Visualization of Global Flow Structures Using Multiple Levels of Topology 

      Leeuw, Wim de; Liere, Robert van (Springer and The Eurographics Association, 1999)
      The technique for visualizing topological information in fluid flows is well known. However, when the technique is used in complex and information rich data sets, the result will be a cluttered image which is difficult to ...
