Interactive Visualization
- Beyond Standard Techniques for Irrelevant Datasets

Thomas Ertl
Institut für Visualisierung und Interaktive Systeme und
Visualisierungsinstitut der Universität Stuttgart

Abstract
Thomas Ertl During the last 20 years visualization has developed into a scientific discipline of its own right at the crossroads of computer graphics, human-computer interaction, and data analysis. Today, interactive visualization techniques play a crucial role in the process of understanding the huge datasets resulting from simulations, sensor measurements, and information systems. The talk will look at the current state of the field which is characterized by the fact that by now elaborate algorithms and efficient GPU implementations exist for many classical visualization problems dealing with 3D scalar and vector data sets. Therefore, it has become obvious that future visualization research cannot only concentrate on optimizing standard techniques for well-known benchmark data sets. A closer cooperation with application domains very often leads to real-life problems whose size and dimension require new approaches often combining known techniques into innovative tools. In this context the talk will present some of the current research results of the visualization group at the University of Stuttgart in the areas of visualization of video streams, molecular dynamics simulations, and patent databases.

Biography
Thomas Ertl received a masters degree in computer science from the University of Colorado at Boulder and a PhD in theoretical astrophysics from the University of Tuebingen. Currently, Dr. Ertl is a full professor of computer science at the University of Stuttgart, Germany and the head of the Visualization and Interactive Systems Institute (VIS) and the Visualization Research Center of the University of Stuttgart (VISUS). Prior to that he was a professor of computer graphics and visualization at the University of Erlangen where he lead the scientific visualization group. Besides that, he is a cofounder and a member of the board of science+computing ag, a Tuebingen based IT company. His research interests include visualization, computer graphics and human computer interaction in general with a focus on volume rendering, flow visualization, multiresolution analysis, parallel and hardware accelerated graphics, large datasets and interactive steering. Dr. Ertl is coauthor of more than 290 scientific publications and he served as a reviewer for most of the conferences and journals in the field. He has been a member of many program committees (e.g. SIGGRAPH, Eurographics) and a papers co-chair for several conferences (e.g. IEEE Visualization, EG/IEEE EuroVIS, Volume Graphics). Since 2007 Dr. Ertl is Editor-in-Chief of the IEEE Transactions on Visualization and Graphics and Vice President of the Eurographics Association. He received the Outstanding Technical Contribution Award of the Eurographics Association and the Technical Achievement Award of the IEEE Visualization and Graphics Technical Committee in 2006 and he was elected as a Member of the Heidelberg Academy of Sciences and Humanities in 2007.
