    • Navigation and Exploration of Interconnected Pathways 

      Streit, Marc; Kalkusch, M.; Kashofer, K.; Schmalstieg, Dieter (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Visualizing pathways, i. e. models of cellular functional networks, is a challenging task in computer assisted biomedicine. Pathways are represented as large collections of interwoven graphs, with complex structures present ...
    • Particle Level Set Advection for the Interactive Visualization of Unsteady 3D Flow 

      Cuntz, Nicolas; Kolb, Andreas; Strzodka, Robert; Weiskopf, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Typically, flow volumes are visualized by defining their boundary as iso-surface of a level set function. Grid-based level sets offer a good global representation but suffer from numerical diffusion of surface detail, ...
    • Physically-based Dye Advection for Flow Visualization 

      Li, Guo-Shi; Tricoche, Xavier; Hansen, Charles (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Dye advection is widely used in experimental flow analysis but has seen less use for visualization in computational fluid dynamics. One possible reason for this disconnect is the inaccuracy of the texture-based approach, ...
    • Quality Isosurface Mesh Generation Using an Extended Marching Cubes Lookup Table 

      Raman, Sundaresan; Wenger, Rephael (The Eurographics Association and Blackwell Publishing Ltd., 2008)
    • Raycasting of Light Field Galleries from Volumetric Data 

      Rezk-Salama, Christof; Todt, Severin; Kolb, Andreas (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      The paper describes a technique to generate high-quality light field representations from volumetric data. We show how light field galleries can be created to give unexperienced audiences access to interactive high-quality ...
    • Results of a User Study on 2D Hurricane Visualization 

      Martin, Joel P.; II, J. Edward Swan; II, Robert J. Moorhead; Liu, Zhanping; Cai, Shangshu (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      We present the results from a user study looking at the ability of observers to mentally integrate wind direction and magnitude over a vector field. The data set chosen for the study is an MM5 (PSU/NCAR Mesoscale Model) ...
    • A Screen Space Quality Method for Data Abstraction 

      Johansson, Jimmy; Cooper, Matthew (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      The rendering of large data sets can result in cluttered displays and non-interactive update rates, leading to time consuming analyses. A straightforward solution is to reduce the number of items, thereby producing an ...
    • Sound Tracing: Rendering Listener Specific Acoustic Room Properties 

      Bellmann, Jens; Michel, Frank; Deines, Eduard; Hering-Bertram, Martin; Mohring, Jan; Hagen, Hans (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      We present an acoustic rendering approach visualizing the listener-specific contribution of frequency-dependent pressure fields on a scene geometry with acoustic reflection and scattering properties. Our method facilitates ...
    • TimeRadarTrees: Visualizing Dynamic Compound Digraphs 

      Burch, Michael; Diehl, Stephan (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      The evolution of dependencies in information hierarchies can be modeled by sequences of compound digraphs with edge weights. In this paper we present a novel approach to visualize such sequences of graphs. It uses radial ...
    • Topology-Preserving lambda_2-based Vortex Core Line Detection for Flow Visualization 

      Schafhitzel, Tobias; Vollrath, Joachim E.; Gois, Joao P.; Weiskopf, Daniel; Castelo, Antonio; Ertl, Thomas (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      We propose a novel vortex core line extraction method based on the lambda_2 vortex region criterion in order to improve the detection of vortex features for 3D flow visualization. The core line is defined as a curve that ...
    • Towards Closing the Analysis Gap: Visual Generation of Decision Supporting Schemes from Raw Data 

      May, Thorsten; Kohlhammer, Jörn (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      The derivation, manipulation and verification of analytical models from raw data is a process which requires a transformation of information across different levels of abstraction. We introduce a concept for the coupling ...
    • Virtual Klingler Dissection: Putting Fibers into Context 

      Schultz, Thomas; Sauber, Natascha; Anwander, Alfred; Theisel, Holger; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Fiber tracking is a standard tool to estimate the course of major white matter tracts from diffusion tensor magnetic resonance imaging (DT-MRI) data. In this work, we aim at supporting the visual analysis of classical ...
    • Visual Abstractions of Solvent Pathlines near Protein Cavities 

      Bidmon, Katrin; Grottel, Sebastian; Bös, Fabian; Pleiss, Jürgen; Ertl, Thomas (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Water is known to play a crucial role in protein structure, flexibility and activity. The use of molecular dynamics simulations allows detailed studies of complex protein-solvent interactions. Cluster analysis and density-based ...
    • Visual Analysis and Semantic Exploration of Urban LIDAR Change Detection 

      Butkiewicz, Thomas; Chang, Remco; Wartell, Zachary; Ribarsky, William (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Many previous approaches to detecting urban change from LIDAR point clouds interpolate the points into rasters, perform pixel-based image processing to detect changes, and produce 2D images as output. We present a method ...
    • Visual Clustering in Parallel Coordinates 

      Zhou, Hong; Yuan, Xiaoru; Qu, Huamin; Cui, Weiwei; Chen, Baoquan (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Parallel coordinates have been widely applied to visualize high-dimensional and multivariate data, discerning patterns within the data through visual clustering. However, the effectiveness of this technique on large data ...
    • Visual Comparison of Hierarchically Organized Data 

      Holten, Danny; Wijk, Jarke J. van (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      We provide a novel visualization method for the comparison of hierarchically organized data. Our technique visualizes a pair of hierarchies that are to be compared and simultaneously depicts how these hierarchies are related ...
    • Visual Inspection of Multivariate Graphs 

      Pretorius, A. Johannes; Wijk, Jarke J. van (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Most graph visualization techniques focus on the structure of graphs and do not offer support for dealing with node attributes and edge labels. To enable users to detect relations and patterns in terms of data associated ...
