Therefore, we introduce the idea of multiple linked views to tensor visualization. In contrast to common tensor visualization methods that only provide a single view to the tensor field, we pursue the idea of providing various perspectives onto the data in attribute and object space. Especially in the context of stress tensors, advanced tensor visualization methods have a young tradition. Thus, we propose a combination of visualization techniques domain experts are used to with statistical views of tensor attributes. The application of this concept to tensor fields was achieved by extending the notion of shape space. It provides an intuitive way of finding tensor invariants that represent relevant physical properties. Using brushing techniques, the user can select features in attribute space, which are mapped to displayable entities in a three-dimensional hybrid visualization in object space. Volume rendering serves as context, while glyphs encode the whole tensor information in focus regions. Tensorlines can be included to emphasize directionally coherent features in the tensor field. We show that the benefit of such a multi-perspective approach is manifold. Foremost, it provides easy access to the complexity of tensor data. Moreover, including wellknown analysis tools, such as Mohr diagrams, users can familiarize themselves gradually with novel visualization methods. Finally, by employing a focus-driven hybrid rendering, we significantly reduce clutter, which was a major problem of other three-dimensional tensor visualization methods.}, language = {en} } @article{KratzBaumHotz2013, author = {Kratz, Andrea and Baum, Daniel and Hotz, Ingrid}, title = {Anisotropic Sampling of Planar and Two-Manifold Domains for Texture Generation and Glyph Distribution}, series = {Transactions on Visualization and Computer Graphics (TVCG)}, volume = {19}, journal = {Transactions on Visualization and Computer Graphics (TVCG)}, doi = {10.1109/TVCG.2013.83}, pages = {1782 -- 1794}, year = {2013}, language = {en} } @article{KratzAuerStommeletal.2013, author = {Kratz, Andrea and Auer, Cornelia and Stommel, Markus and Hotz, Ingrid}, title = {Visualization and Analysis of Second-Order Tensors: Moving Beyond the Symmetric Positive-Definite Case}, series = {Computer Graphics Forum - State of the Art Reports}, volume = {1}, journal = {Computer Graphics Forum - State of the Art Reports}, doi = {10.1111/j.1467-8659.2012.03231.x}, pages = {49 -- 74}, year = {2013}, language = {en} } @inproceedings{AuerStripfKratzetal.2012, author = {Auer, Cornelia and Stripf, Claudia and Kratz, Andrea and Hotz, Ingrid}, title = {Glyph- and Texture-based Visualization of Segmented Tensor Fields}, series = {GRAPP/IVAPP Proc.

Here we combine the first large-scale serial electron tomography of whole mitotic spindles in early C. elegans embryos with live-cell imaging to reconstruct all microtubules in 3D and identify their plus- and minus-ends. We classify them as kinetochore (KMTs), spindle (SMTs) or astral microtubules (AMTs) according to their positions, and quantify distinct properties of each class. While our light microscopy and mutant studies show that microtubules are nucleated from the centrosomes, we find only a few KMTs directly connected to the centrosomes. Indeed, by quantitatively analysing several models of microtubule growth, we conclude that minus-ends of KMTs have selectively detached and depolymerized from the centrosome. In toto, our results show that the connection between centrosomes and chromosomes is mediated by an anchoring into the entire spindle network and that any direct connections through KMTs are few and likely very transient.}, language = {en} } @inproceedings{KratzKettlitzHotz2011, author = {Kratz, Andrea and Kettlitz, Nino and Hotz, Ingrid}, title = {Particle-Based Anisotropic Sampling for Two-Dimensional Tensor Field Visualization}, series = {Vision Modeling and Visualization (VMV'11)}, booktitle = {Vision Modeling and Visualization (VMV'11)}, publisher = {Eurographics Association target}, pages = {145 -- 152}, year = {2011}, language = {en} } @misc{KratzMeyerHotz2011, author = {Kratz, Andrea and Meyer, Bj{\"o}rn and Hotz, Ingrid}, title = {A Visual Approach to Analysis of Stress Tensor Fields}, series = {Scientific Visualization: Interactions, Features, Metaphors}, volume = {2}, journal = {Scientific Visualization: Interactions, Features, Metaphors}, editor = {Hagen, Hans}, publisher = {Schloss Dagstuhl-Leibniz-Zentrum fuer Informatik}, address = {Dagstuhl, Germany}, doi = {10.4230/DFU.Vol2.SciViz.2011.188}, pages = {188 -- 211}, year = {2011}, language = {en} } @inproceedings{KratzSchoeneichZobeletal., author = {Kratz, Andrea and Sch{\"o}neich, Marc and Zobel, Valentin and Burgeth, Bernhard and Scheuermann, Gerik and Hotz, Ingrid and Stommel, Markus}, title = {Tensor Visualization Driven Mechanical Component Design}, series = {Proc.
