Virtual reality (VR) is a useful tool for visualizations, either for reconstruction of historical environments (much used by archaeologists) or for creating controllable environments in which you can do other measurements, for example eye tracking. An important detail with a virtual reality visualization system is the possibility to create interaction with the environment. This makes it an interesting tool not only for research, but also for exhibitions in museums and similar situations.The Humanities Lab has, in collaboration with the VR-lab at Designcenter, a cave, consisting of three walls and and a floor with stereoscopic 3d and headtracking, for a visual reproduction of the models.To be able to create 3D-models to use in the visualization systems, there are also 3D recording devices. One Faro Focus phaseshift laserscanner for larger environments, a handheld Artec Eva scanner for mediumsized objects and two NextEngine triangulation 3D-scanners for smaller objects. A differential GPS-system for recording 3D-maps of landscapes and a couple of ordinary cameras and lenses used with different photogrammetry techniques. There is also a motion capture system for recording 3D-movements.As for software there is a whole range of different software used in different situations.
