The 3D CAVE is an excellent tool for research and teaching of complex spatial models
The 3-sided computer animated virtual environment (3D CAVE) at the Institute of Geoscience offers a modern immersive visualization that supports an improved and faster analysis of complex spatial and temporal multi-scale datasets. 
Based on nearly 10 years of experience, we focus on a fast data integration / easy-access usability, building on (1) a fast and smooth data / model transfer from standard software to 3-dimensional visualization, and (2) the immediate possibility of discussing and manipulating models with groups up to 10 users directly within the visualization cluster. The setup offers an inspiring and supportive learning environment, allowing professional interaction with 3D data, presentation and training, as well as knowledge transfer with non-experts.
The focus of the lab is to project complex data sets spatially in order to visually analyze data structures and their internal relationships. Simultaneously, sonification and haptification techniques should be used to detect spatiotemporal patterns. 
The laboratory comprises a computer cluster and a visualization platform. The computer cluster manages the massive amounts of data, performs calculations and controls the visualization. The visualization platform allows the temporal-spatial representation of the data through special projection technology. Viewers can interact with the projection system and thus grasp the multidimensional relationships. A tracking system with various interactive tools allows this in-situ communication with the data. 
In addition to its scientific use, the lab is of central importance for industrial cooperation. Numerous large and medium-sized companies have registered a need to use the lab. In the course of more intensive cooperation, new (third-party funded) projects with industrial participation have been promised. The laboratory is an integral part of the BMBF joint project PROGRESS and is integrated into the pearls and Geo.X research alliances. Financing comes from federal funds.
Dr. Gerold Zeilinger
Head and Geological Applications
Since 2005 Researcher at Geosciences in Potsdam. Diploma in Geology in 1997, Tübingen University. Doctor degree 2002 at ETH Zurich, with studies in NW-Himalaya using modern field techniques for plate collision reconstruction. Followed by postdoc positions in Genève, Bern and Zurich with research foci on deformation processes and feed­back mechanisms acting between erosion and crustal response. Current projects in geological GIS/3D applications include remote sensing methods for surface change detection and quantification.
Dr. Matthias Ohrnberger
Geophysical Applications
Since 1997 researcher at Institute of Geosciences of University of Potsdam. 
Diploma in Geophysics from LMU Munich, Doctoral degree in Geophysics obtained 2001 at University of Potsdam with research on volcano seismology at the Indonesian high-risk volcano Merapi. Focus of research has been multi-component digital signal processing and the application of intelligent (knowledge driven) data analysis methods to seismological problems. Special interest on seismologically observable dynamic processes from tiniest environmental and anthropogenic signals to megathrust Earthquakes. Current projects are related to real-time impact assessment of mid-sized EQ in the Mediterranean, the long-term observation of earthquake swarms at a 3D-sensor network and the use of large-N sensor networks for the observations of 3D wave propagation phenomena.
