      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 ...
    • DTI Visualization with Streamsurfaces and Evenly-Spaced Volume Seeding 

      Vilanova, A.; Berenschot, G.; Pul, C. van (The Eurographics Association, 2004)
      Experimental evidence has shown that water diffusion is anisotropic in organized tissues such as white matter or muscles. Diffusion Tensor Imaging is a non-invasive MR technique that measures water diffusion. DTI is used ...
    • Efficient Display of Background Objects for Virtual Endoscopy using Flexible First-Hit Ray Casting 

      Neubauer, A.; Forster, M.; Wegenkittl, R.; Mroz, L.; Bühler, K. (The Eurographics Association, 2004)
      Many applications of virtual endoscopy require the display of background objects behind the semi-transparent surface of the investigated organ. This paper deals with pre-processing and visualization of background objects ...
    • 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 ...

    • Generalized Distance Transforms and Skeletons in Graphics Hardware 

      Strzodka, R.; Telea, A. (The Eurographics Association, 2004)
      We present a framework for computing generalized distance transforms and skeletons of two-dimensional objects using graphics hardware. Our method is based on the concept of footprint splatting. Combining different splats ...
    • 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 ...
    • 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 ...
    • 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 ...
