Lenne3D (www.lenne3d.de) was a joint project, initiated by Philip Paar and Dr. Werner at the ZALF (Müncheberg, Germany) together with Prof. Deussen (Univ. Konstanz), Prof. Hege (Zuse Institut Berlin), and Prof. Döllner (HPI, Potsdam).
As most important results, new 3D modeling, rendering, and interaction techniques have been developed to cope with complex, vegetation-based virtual 3D landscapes.
In the context of Lenne3D project, the HPI was responsible for developing the system architecture, which is illustrated below. HPI deployed the LandXplorer system platform of 3D Geo as authoring system for virtual 3D landscapes.
