    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 ...

    Hierarchical Opacity Optimization for Sets of 3D Line Fields 

    Günther, Tobias; Rössl, Christian; Theisel, Holger (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Abstract The selection of meaningful lines for 3D line data visualization has been intensively researched in recent years. Most approaches focus on single line fields where one line passes through each domain point. This ...

    Opacity Optimization for Surfaces 

    Günther, Tobias; Schulze, Maik; Esturo, Janick Martinez; Rössl, Christian; Theisel, Holger (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    In flow visualization, integral surfaces rapidly tend to expand, fold and produce vast amounts of occlusion. While silhouette enhancements and local transparency mappings proved useful for semi-transparent depictions, they ...

    Automating Transfer Function Design with Valley Cell-Based Clustering of 2D Density Plots 

    Wang, Yunhai; Zhang, Jian; Lehmann, Dirk J.; Theisel, Holger; Chi, Xuebin (The Eurographics Association and Blackwell Publishing Ltd., 2012)
    Two-dimensional transfer functions are an effective and well-accepted tool in volume classification. The design of them mostly depends on the user's experience and thus remains a challenge. Therefore, we present an approach ...

    Topological Construction and Visualization of Higher Order 3D Vector Fields 

    Weinkauf, Tino; Theisel, Holger; Hege, Hans-Christian; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing, Inc, 2004)
    We present the first algorithm for constructing 3D vector fields based on their topological skeleton. The skeleton itself is modeled by interactively moving a number of control polygons. Then a piecewise linear vector field ...

    Vortex Analysis in Uncertain Vector Fields 

    Otto, Mathias; Theisel, Holger (The Eurographics Association and Blackwell Publishing Ltd., 2012)
    We present an approach to extract and visualize vortex structures in uncertain vector fields. For this, we generalize the concepts of the most common vortex detectors to uncertain vector fields, namely the λ ...

    Sets of Globally Optimal Stream Surfaces for Flow Visualization 

    Schulze, Maik; Esturo, Janick Martinez; Günther, Tobias; Rössl, Christian; Seidel, Hans-Peter; Weinkauf, Tino; Theisel, Holger (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Stream surfaces are a well-studied and widely used tool for the visualization of 3D flow fields. Usually, stream surface seeding is carried out manually in time-consuming trial and error procedures. Only recently automatic ...

    MCFTLE: Monte Carlo Rendering of Finite-Time Lyapunov Exponent Fields 

    Günther, Tobias; Kuhn, Alexander; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Traditionally, Lagrangian fields such as finite-time Lyapunov exponents (FTLE) are precomputed on a discrete grid and are ray casted afterwards. This, however, introduces both grid discretization errors and sampling errors ...

    Visualnostics: Visual Guidance Pictograms for Analyzing Projections of High-dimensional Data 

    Lehmann, Dirk J.; Kemmler, Fritz; Zhyhalava, Tatsiana; Kirschke, Marco; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    The visual analysis of multivariate projections is a challenging task, because complex visual structures occur. This causes fatigue or misinterpretations, which distorts the analysis. In fact, the same projection can lead ...

    Source Inversion by Forward Integration in Inertial Flows 

    Günther, Tobias; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Inertial particles are finite-sized objects traveling with a certain velocity that differs from the underlying carrying flow, i.e., they are mass-dependent and subject to inertia. Their backward integration is in practice ...
