      Brandes, U.; Dwyer, T.; Schreiber, F. (The Eurographics Association, 2004)
      Phylogenetic trees are built by examining differences in the biological traits of a set of species. An example of such a trait is a biological network such as a metabolic pathway, common to all species but with subtle ...
    • A Cluster-Space Visual Interface for Arbitrary Dimensional Classification of Volume Data 

      Tzeng, Fan-Yin; Ma, Kwan-Liu (The Eurographics Association, 2004)
      In volume visualization, users typically specify transfer functions to classify the data and assign visual attributes to each material class. Higher-dimensional classification makes it easier to differentiate material ...
    • Efficient Isosurface Tracking Using Precomputed Correspondence Table 

      Ji, Guangfeng; Shen, Han-Wei (The Eurographics Association, 2004)
      Feature tracking is a useful method for visualizing and analyzing time-varying scalar fields. It allows scientists to focus on regions of interest and track their evolution and interaction over time. To allow the user to ...
    • Visualization of Anatomic Tree Structures with Convolution Surfaces 

      Oeltze, S.; Preim, B. (The Eurographics Association, 2004)
      We present a method for visualizing anatomic tree structures, such as vasculature and bronchial trees based on clinical CT- or MR data. The vessel skeleton as well as the diameter information per voxel serve as input. Our ...
    • Medical Applications of Multi-Field Volume Rendering and VR Techniques

      This paper reports on a new approach for visualizing multi-field MRI or CT datasets in an immersive environment with medical applications. Multi-field datasets combine multiple scanning modalities into a single 3D, ...
    • A Botanically Inspired High-Dimensional Visualization with Multivariate Glyphs 

      Chlan, E. B.; Rheingans, Penny (The Eurographics Association, 2004)
      It is difficult for the average viewer to assimilate and comprehend huge amounts of high-dimensional data. It is important to present data in a way that allows the user a high level understanding of the overall organization ...
    • Volume Visualization and Visual Queries for Large High-Dimensional Datasets 

      Reina, G.; Ertl, T. (The Eurographics Association, 2004)
      We propose a flexible approach for the visualization of large, high-dimensional datasets. The raw, highdimensional data is mapped into an abstract 3D distance space using the FastMap algorithm, which helps, together with ...
    • Visual Component Analysis 

      Müller, Wolfgang; Alexa, Marc (The Eurographics Association, 2004)
      We propose to integrate information visualization techniques with factor analysis. Specifically, a principal direction derived from a principal component analysis (PCA) of the data is displayed together with the data in a ...
    • 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 ...
    • 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 ...
    • Ray Casting Curved-Quadratic Elements 

      Wiley, D. F.; Childs, H. R.; Hamann, B.; Joy, K. I. (The Eurographics Association, 2004)
      We present a method for ray casting curved-quadratic elements in 3D. The advantages of this approach is that a curved element can be directly visualized. Conventionally, higher-order elements are tessellated with several ...
