3D visualization and virtual reality for cultural heritage diagnostic

Over the last years a lot of new technologies for Cultural Heritage Diagnostic have been developed in these years. In particular laser scanner surveys integrated with digital photogrammetry and also multi-spectral surveys have begun to become very useful and inalienable tools for not invasive diagnosis. Inside SIDART Project (Integrated System for Cultural Heritage Diagnostic) we developed software for visualize and elaborate triangulated surfaces coming from high resolution laser scanner survey. In this paper we wanted to present the most innovative aspect of our study, consisting in the possibility to visualize and to work in default mode or in immersive Stereoscopy (3D mode). In this way the operator can perceive the third dimension and the "virtual investigation" of the object become more realistic. This let to take consideration in more simple, natural and correct way and also reduce the possibility to make evaluation mistakes due to the false prospective of the classic visualization.
