Time-of-Flight Range Data
Physically correct particle systems (PS) are designed to add essential properties to the virtual world. This work introduces a real-time GPU implementation of both the simulation and rendering of a dynamically-growing particle system of up to 1 million particles.
Level sets are used for the representation and evolution of closed surfaces. The particle level set (PLS) method combines the advantages of grid-based level set approaches and particle-based methods by interchanging the information between the grid and the particles.
Flow visualizations can help, e.g., climate researchers to explore flow characteristics. In this work, the Particle Level Set (PLS) method is adapted to volumetric dye advection via streak volumes, and to the visualization by time surfaces and path volumes. Additionally, a complete GPU-based particle engine and framework for the real-time visualization of unsteady climate flow data sets is presented.

Processing and Analysis of Sensor Data
The DFG-project "Interactive Analysis and Visualization of Multi-modal Confocal Raman Microscopy Data" involves the analysis and visualization of the measurement data obtained from our multispectra
Fast separation of direct and global scene components is subject to resolution loss. Therefore, we developed a constrained up-scaling technique in order to perform high-resolution acquisitions for time-critical scenes.
The processing of THz data allows to find object properties in a frequency range that is not well explored, yet. Current imaging technologies are not useable in this part of the spectrum. For example, security screenings and material detection can be improved.
Using depth maps, stereoscopic 3D video can be synthesized from conventional 2D video, and viewing conditions for 3D video can be improved by on-the-fly retargeting to different display geometries.
