Berlin virtual 3D city model: Between 2003 and 2005, the computer Graphics Systems Group developed the Berlin city 3D model system architecture. In contrast to previous efforts, the virtual 3D city model of Berlin acts as an integration platform for 2D and 3D geodata rather than only being a 3D graphics model.
A 3D reconstruction of Roman Cologne producing a fully navigable 3D model of Roman Cologne as it existed at a certain point in time. The digital reconstruction of ancient Cologne was a joint effort by the Archaeological Institute of the University of Cologne, the Köln International School of Design (KISD) the Cologne University of Applied Sciences, the University of Potsdam’s Hasso-Plattner Institute, and the Cologne Romano-Germanic Museum (RGM).
Lenne3D was a joint project by ZALF Germany, Univ. Konstanz, Zuse Institut Berlin, and HPI, Potsdam. The project developed a new 3D modeling, rendering, and interaction techniques to cope with complex, vegetation-based virtual 3D landscapes.
