    • Real-Time Advection and Volumetric Illumination for the Visualization of 3D Unsteady Flow 

      Weiskopf, Daniel; Schafhitzel, Tobias; Ertl, Thomas (The Eurographics Association, 2005)
      This paper presents an interactive technique for the dense texture-based visualization of unsteady 3D flow, taking into account issues of computational efficiency and visual perception. High efficiency is achieved by a ...

    • Scalable, Robust Visualization of Very Large Trees 

      Beermann, Dale; Munzner, Tamara; Humphreys, Greg (The Eurographics Association, 2005)
      The TreeJuxtaposer system [MGT*03] allowed visual comparison of large trees with guaranteed visibility of landmarks and Focus+Context navigation. While that system allowed exploration and comparison of larger datasets than ...

    • A Simple and Novel Seed-Set Finding Approach for Iso-Surface Extraction 

      Hung, Chiang-Han; Yang, Chuan-kai (The Eurographics Association, 2005)
      Iso-surface extraction is one of the most important approaches for volume rendering, and iso-contouring is one of the most effective methods for iso-surface extraction. Unlike most other methods having their search domain ...

    • Spatialized Transfer Functions 

      Roettger, Stefan; Bauer, Michael; Stamminger, Marc (The Eurographics Association, 2005)
      Multi-dimensional transfer functions are an efficient way to visualize features in scalar volume data produced by CT or MRI scanners. However, the optimal transfer function is difficult to find in general. We present an ...

    • Spline-Based Gradient Filters For High-Quality Refraction Computations in Discrete Datasets 

      Li, Shengying; Mueller, Klaus (The Eurographics Association, 2005)
      Based on the finding that refraction imposes significantly higher demands onto gradient filters than illumination and shading, we evaluate the family of spline filters as a good alternative to the cubic filters, which so ...

    • Tiled Parallel Coordinates for the Visualization of Time-Varying Multichannel EEG Data 

      Caat, Michael ten; Maurits, N. M.; Roerdink, J. B. T. M. (The Eurographics Association, 2005)
      The field of visualization assists data interpretation in many areas, but some types of data are not manageable by existing visualization techniques. This holds in particular for time-varying multichannel EEG data. No ...

    • Transfer Functions for Imaging Spectroscopy Data using Principal Component Analysis 

      Broersen, Alexander; Liere, Robert van (The Eurographics Association, 2005)
      In this paper we present a new application of the principal component analysis (PCA) to generate multidimensional transfer functions. These transfer functions are needed in the volumetric visualization of spectral data to ...

    • Vector Field Analysis and Visualization through Variational Clustering 

      McKenzie, Alexander; Lombeyda, Santiago V.; Desbrun, Mathieu (The Eurographics Association, 2005)
      Scientific computing is an increasingly crucial component of research in various disciplines. Despite its potential, exploration of the results is an often laborious task, owing to excessively large and verbose datasets ...

    • Version-Centric Visualization of Code Evolution 

      Voinea, S. Lucian; Telea, Alexandru; Chaudron, Michel (The Eurographics Association, 2005)
      The source code of software systems changes many times during the system lifecycle. We study how developers can get insight in these changes in order to understand the project context and the product artifacts. For this ...

    • VIS-a-VE: Visual Augmentation for Virtual Environments in Surgical Training 

      Chung, Adrian; Deligianni, Fani; Shah, Pallav; Wells, Athol; Yang, Guang-Zhong (The Eurographics Association, 2005)
      Photo-realistic rendering combined with vision techniques is an important trend in developing next generation surgical simulation devices. Training with simulator is generally low in cost and more efficient than traditional ...

    • VisBiz: A Business Process Visualization Case Study 

      Hao, Ming; Keim, Daniel A.; Dayal, Umeshwar; Schneidewind, Joern (The Eurographics Association, 2005)
      Business process management involves many parameters and relationships and is modeled as complex business process workflows. A common way to analyze the process data is by using flowcharts. Visual analysis of a largescale ...

    • Visualisation and Analysis of Large and Complex Scale-free Networks 

      Ahmed, Adel; Dywer, Tim; Hong, Seok-Hee; Murray, Colin; Song, Le; Wu, Ying Xin (The Eurographics Association, 2005)
      Scale-free networks appear in many application domains such as social and biological networks [BA99, BB03, BO04]. Roughly speaking, scale-free networks have power-law degree distribution, ultra-short average path length ...

    • Visualization for Validation and Improvement of Three-dimensional Segmentation Algorithms 

      Weber, Gunther H.; Hendriks, Cris L. Luengo; Keränen, Soile V. E.; Dillard, Scott E.; Ju, Derek Y.; Sudar, Damir; Hamann, Bernd (The Eurographics Association, 2005)
      The Berkeley DrosophilaTranscription Network Project (BDTNP) is developing a suite of methods that will allow a quantitative description and analysis of three dimensional (3D) gene expression patterns in an animal with ...

    • Visualization of Computer-Modeled Forests for Forest Management 

      Mohammadi-Aragh, Mahnas Jean; Fujisaki, Ikuko; Irby, Derek; Evans, David; Moorhead, Robert; Roberts, Scott (The Eurographics Association, 2005)
      Forest management is a costly and time-consuming activity. Remote sensing has the potential to improve the process by making it cheaper and more efficient, but only if appropriate characteristics can be determined from ...
