It already has been shown that, by employing the metaphor of a fabric structure, tensor data can be visualized precisely on surfaces where the two eigendirections in the plane are illustrated as thread-like structures. This leads to a continuous visualization of most salient features of the tensor data set. We introduce a novel approach to compute such a visualization from tensor field data that is motivated by image-space line integral convolution (LIC). Although our approach can be applied to arbitrary, non-selfintersecting surfaces, the main focus lies on special surfaces following important features, such as surfaces aligned to the neural pathways in the human brain. By adding a postprocessing step, we are able to enhance the visual quality of the of the results, which improves perception of the major patterns.}, isbn = {978-3-642-27342-1}, doi = {10.1007/978-3-642-27343-8_4}, url = {http://dx.doi.org/10.1007/978-3-642-27343-8_4}, author = {Eichelbaum, Sebastian and Mario Hlawitschka and Bernd Hamann and Gerik Scheuermann}, editor = {Laidlaw, David H. and Vilanova, Anna} } @inbook {eichelbaum2010b, title = {Image-space Tensor Field Visualization Using a LIC-like Method}, booktitle = {Visualization in Medicine and Life Sciences 2}, series = {Mathematics and Visualization}, year = {2012}, pages = {193{\textendash}210}, publisher = {Springer-Verlag}, organization = {Springer-Verlag}, abstract = {Tensors are of great interest to many applications in engineering and in medical imaging, but a proper analysis and visualization remains challenging. Physics-based visualization of tensor fields has proven to show the main features of symmetric second-order tensor fields, while still displaying the most important information of the data, namely the main directions in medical diffusion tensor data using texture and additional attributes using color-coding, in a continuous representation. Nevertheless, its application and usability remains limited due to its computational expensive and sensitive nature. We introduce a novel approach to compute a fabric-like texture pattern from tensor fields motivated by image-space line integral convolution (LIC). Although, our approach can be applied to arbitrary, non-selfintersecting surfaces, we are focusing on special surfaces following neural fibers in the brain. We employ a multi-pass rendering approach whose main focus lies on regaining three-dimensionality of the data under user interaction as well as being able to have a seamless transition between local and global structures including a proper visualization of degenerated points.}, author = {Eichelbaum, Sebastian and Mario Hlawitschka and Bernd Hamann and Gerik Scheuermann}, editor = {Lars Linsen and Bernd Hamann and Hans Hagen and Hege, H.-C.} } @conference {631, title = {Topology-based Visualization and Analysis of High-dimensional Data and Time-varying Data at the Extreme Scale}, booktitle = {DOE Exascale Research Conference}, year = {2012}, month = {April}, address = {Portland, OR}, author = {Gunther H.
