A disadvantage of hierarchical fiber clustering is its difficult visualization. The simple presentation as a 2D tree is visually too complex because of the amount of several thousand leaves. We present a framework that allows the modification of the dendrogram visualization in a flexible way. The modified dendrogram visualization can convey additional information that grants an easier orientation within the hierarchical clustering. Besides the interaction with the dendrogram itself, it is also possible to make use of a 3D view and a clustering preview. To illustrate potential use cases, we present two usage examples that show the versatility of our framework. }, author = {Stefan Philips and Mario Hlawitschka and Gerik Scheuermann} } @conference {Philips2013, title = {Parallelized Global Brain Tractography}, booktitle = {Proceedings of the 18th International Fall Workshop on Vision, Modeling, and Visualization (VMV13)}, year = {2013}, pages = {97{\textendash}104}, author = {Stefan Philips and Mario Hlawitschka and Gerik Scheuermann} } @booklet {eichelbaum2010d, title = {OpenWalnut: A New Tool for Multi-modal Visualization of the Human Brain}, year = {2010}, abstract = {In the course of the ongoing research into neurological diseases and the function and anatomy of the brain, a large variety of examination techniques has evolved. The different techniques aim at findings for different research questions or different viewpoints of a single task. Considering the different applications, it is evident that, for many research areas, only a combination of multiple techniques can help answering the posed questions. To name only one example, the combination of dwMRI and fMRI with an anatomical context provided by T1 MRI images is very common. To be able to analyze the data measured by the different techniques, a tool that can efficiently visualize the different modalities simultaneously is needed. The software (called {\em OpenWalnut}) we will present in this poster aims at exactly this task. It does not only allow to display the different modalities together, but also provides tools to analyze their interdependence and relations. In the following, we will provide you with an overview of OpenWalnut{\textquoteright}s features. Its simplicity, making it a useful visualization tool, on the one hand and its powerful and generic framework for computer scientist researchers on the other hand.}, author = {Eichelbaum, Sebastian and Mathias Goldau and Stefan Philips and Andr{\'e} Reichenbach and Ralph Schurade and Alexander Wiebel} }
