The CSG Visualization develops solutions for interactive (optionally immersive) visualization of scientific datasets.
The latest developments in ever faster computing hardware as well es efficient algorithms allow domain scientist to generate fast, more reliable and more detailed simulations and models of real-world phenomena. This, however, also increases the complexity of the data and poses a variety of challenges. One of those challenges is to make sense of the data and cope with the sheer amount of information to process as well as monitoring simulations early on.
One common way to make the analysis of data and processes easier, is to use visualization which means mapping complex information to visual abstractions which harnesses the humans’ strong visual sense such that even large quantities of data and interconnected relations can be communicated easily.
As such, the task of the CSG Visualization is to provide state-of-the-art visualization methods for variety of data being used within the NHR context. This includes spatial visualizations of data in immersive 3D environments (VR) or 2D/3D rendering applications as well as interactive analysis tools tailored to specific domains and users. In situations, where no off-the-shelf visualization exists, the task of our group is to develop new methods beyond state of the art.
Current research topics:
- In-Situ Visualization: Provide instant visual feedback during simulations to monitor and judge current processes
- Uncertainty Visualization: Quantify the trustworthiness of the data
- Immersive Visualization
- Analyze challenges and provide experience in possible visualizations that aid the process
