PanoLab and TrackingLab: Setups in which the Virtual Tübingen Modell is mainly used

The half-spherical screen of the PanoLab allows the simulation of large visual fields providing an increased degree of immersion. In the large room of the Tracking Lab, experiments are conducted in which participants can walk through and explore extensive virtual worlds that are displayed via Head-Mounted Displays.


The geometry of Virtual Tuebingen was initially created using Multigen Creator. Textures were processed using Photomodeler and an in-house developed tool called CorTex, to automatically correct distorted images. Later on, the model was converted into the max format, currently any modifications/extensions to the model are done with 3ds Max by Autodesk .

To render and display the Virtual Tuebingen in realtime, a graphics engine based on OpenGL Performer by SGI was developed in-house. This engine then became part of the veLib, and was modified to use pure OpenGL together with the SDL. As a 3d format to export all the data from 3ds max into the veLib, we currently use VRML, since it is easy to use and is supported by many modeling programs.
