    • Graph Drawing by Subspace Optimization 

      Koren, Yehuda (The Eurographics Association, 2004)
      We show a novel approach for accelerating the computation of graph drawing algorithms. The method is based on the notion that we can find a subspace with a relatively low dimensionality that captures the "nice" layouts of ...
    • Illustrating Surfaces in Volume 

      Yuan, Xiaoru; Chen, Baoquan (The Eurographics Association, 2004)
      This paper presents a novel framework for illustrating surfaces in a volume. Surfaces are illustrated by drawing only feature lines, such as silhouettes, valleys, ridges, and surface hatching strokes, and are embedded in ...
    • Adaptive Volume Construction from Ultrasound Images of a Human Heart 

      Reis, Gerd; Bertram, Martin; Lengen, Rolf H. van; Hagen, Hans (The Eurographics Association, 2004)
      We present a volume modelling approach based on sequences of two-dimensional ultrasound images. Though generally applicable to arbitrary freehand ultrasound, our method is designed for the reconstruction of timevarying ...

      Amir, Amihood; Kashi, Reuven; Keim, Daniel A.; Netanyahu, Nathan S.; Wawryniuk, Markus (The Eurographics Association, 2004)
      Scatterplots are widely used in exploratory data analysis and class visualization. The advantages of scatterplots are that they are easy to understand and allow the user to draw conclusions about the attributes which span ...
    • Techniques for Visualizing Multi-Valued Flow Data 

      Urnessy, Timothy; Interrante, Victoria; Longmire, Ellen; Marusic, Ivan; Ganapathisubramani, Bharathram (The Eurographics Association, 2004)
      In this paper we discuss several techniques to display multiple scalar distributions within an image depicting a 2D flow field. We first address how internal contrast and mean luminance can effectively be used to represent ...
    • TimeHistograms for Large, Time-Dependent Data 

      Kosara, Robert; Bendix, Fabian; Hauser, Helwig (The Eurographics Association, 2004)
      Histograms are a very useful tool for data analysis, because they show the distribution of values over a data dimension. Many data sets in engineering (like computational fluid dynamics, CFD), however, are time-dependent. ...
    • Case Study: Visual Analysis of Complex, Time-Dependent Simulation Results of a Diesel Exhaust System 

      Doleisch, Helmut; Mayer, Michael; Gasser, Martin; Wanker, Roland; Hauser, Helwig (The Eurographics Association, 2004)
      In previous work we have presented visualization techniques that provide engineers with a high degree of interactivity and flexibility for analyzing large, time-dependent, and high-dimensional data sets resulting from CFD ...
    • Software Landscapes: Visualizing the Structure of Large Software Systems 

      Balzer, Michael; Noack, Andreas; Deussen, Oliver; Lewerentz, Claus (The Eurographics Association, 2004)
      Modern object-oriented programs are hierarchical systems with many thousands of interrelated subsystems. Visualization helps developers to better comprehend these large and complex systems. This paper presents a three-dimensional ...
    • Interactively Visualizing Procedurally Encoded Scalar Fields 

      Jang, Yun; Weiler, Manfred; Hopf, Matthias; Huang, Jingshu; Ebert, David S.; Gaither, Kelly P.; Ertl, Thomas (The Eurographics Association, 2004)
      While interactive visualization of rectilinear gridded volume data sets can now be accomplished using texture mapping hardware on commodity PCs, interactive rendering and exploration of large scattered or unstructured data ...
    • Interactive High Quality Trimmed NURBS Visualization Using Appearance Preserving Tessellation 

      Guthe, M.; Balázs, Á.; Klein, R. (The Eurographics Association, 2004)
      Trimmed NURBS models are the standard representation used in CAD/CAM systems and accurate visualization of large trimmed NURBS models at interactive frame rates is of great interest for industry. To visualize the quality ...
    • Boundary Switch Connectors for Topological Visualization of Complex 3D Vector Fields 

      Weinkauf, T.; Theisel, H.; Hege, H.-C.; Seidel, H.-P. (The Eurographics Association, 2004)
      One of the reasons that topological methods have a limited popularity for the visualization of complex 3D flow fields is the fact that their topological structures contain a number of separating stream surfaces. Since these ...
    • Superquadric Tensor Glyphs 

      Kindlmann, Gordon (The Eurographics Association, 2004)
      Tensor field visualization is a challenging task due in part to the multi-variate nature of individual tensor samples. Glyphs convey tensor variables by mapping the tensor eigenvectors and eigenvalues to the orientation ...
    • Accuracy Evaluation of Different Centerline Approximations of Blood Vessels 

      Cruz, A. La (The Eurographics Association, 2004)
      Accurate determination of the vessel axis is a prerequisite for automated visualization and quantification of artery diseases. This paper presents an evaluation of different methods for approximating the centerline of the ...
    • High-Quality Lighting and Efficient Pre-Integration for Volume Rendering 

      Lum, Eric B.; Wilson, Brett; Ma, Kwan-Liu (The Eurographics Association, 2004)
      Pre-integrated volume rendering is an effective technique for generating high-quality visualizations. The precomputed lookup tables used by this method are slow to compute and can not include truly pre-integrated lighting ...
    • Texture-Based Flow Visualization on Isosurfaces from Computational Fluid Dynamics 

      Laramee, Robert S.; Schneider, Jürgen; Hauser, Helwig (The Eurographics Association, 2004)
      Isosurfacing, by itself, is a common visualization technique for investigating 3D vector fields. Applying texturebased flow visualization techniques to isosurfaces provides engineers with even more insight into the ...
