This scene shows a driving simulation database of Zürich, Switzerland, generated for the DISI-Xtreme image generator from Rheinmetall with the DBGS Xtreme road generator and procedurally based buildings. The upper part shows the complex details of an inner city roundabout area. The lower part shows the powerful lighting capabilities of DISI Xtreme for night scenes. Rheinmetall combines the architecture of a high end game engine with the functionality of a simulation multi channel image generator to support high fidelity and complex visual solutions for land, naval/marine and flight applications. The benefits of modern game engines with the high rendering quality are available on a simulation level from desktop training systems up to large simulators.
