Interactive Visualization Group
We deal with interactive visual analysis of complex scientific data. We integrate simulation, visualization, and analysis in unified workflows in order to support experts in various domains.
Modern simulation techniques generate large amounts of complex data.The simulation models have tens, hundreds, or even thousands of parameters. Exploring and tuning such models is a very challenging task. It can be successfully solved only by a combination of automatic and interactive methods.
The research in this group targets a synergy of interactive visualization, and computational analysis to simplify and speedup the entire workflow of exploration and optimization of complex engineering systems.
We provide novel methods for the preparation of simulations, controlling multiple simulation runs, and the interactive visual analysis of complex 3D and nD simulation results. We focus on complex data which usually includes many curves, surfaces, or other complex structures, per simulation run.
Our application domains include automotive engineering, geology, and medicine.
To support the initial setup of simulation domains, we also investigate visual techniques for interactive mesh editing and domain decomposition. We enable the exploration of high-dimensional parameter spaces by allowing the user to effectively create and steer simulation ensembles thereof. Our steering solutions, Hybrid steering and Hierarchical Steering, make it possible to simultaneously explore and analyze several simulation models of varying complexity.

SimVis is an interactive visual analysis platform for large, multi-variate, and time-dependent 3D simulation data on unstructured grids. SimVis stands for Simulation Visualization, which also describes its main application field.
ComVis is a coordinated multiple views research platform. It supports advanced interaction, multiple composite brushes, and a simultaneous analysis of multiple data tables. Besides standard scalar attributes, it also supports complex data, such as curves, surfaces, sets, trajectories, and events along trajectories, as atomic units in records.
