Building Virtual Tuebingen

The creation of Virtual Tübingen consisted of two processes: processing of geometry (the three-dimensional 'structure' of the architecture) and processing of textures (the 'images', that is, photographs of the buildings and structures providing information about their visual appearance). For a house this means that creating the walls is separated from creating the textures that will be put onto these walls.

This division was motivated by the fact that by combining lower-resolution geometric data (which we had for most of the houses from architectural models of Tübingen) and high-resolution textures (which we get by simply taking photographs) we can create a very realistic model of Tübingen's houses and streets. This approach of separating geometry and texture is different from, for example, modeling of landscapes which would have required a different approach (e.g., using high resolution aerial photographs).


Current status

Currently, we have stopped the process of extending the model which now includes approx. 200 houses and covers an area of approx. 500x150 m. We are investigating methods to increase the rendering speed and quality and adding more realism to the scene such as realtime shadows or even animated characters.
