VR and Holographic Information System for the Conservation Project

The presented research resulted from an unusual educational experience that brought lecturers in surveying and three-dimensional digitalization with lecturers in heritage conservation. The courses explore the possibility of utilizing digital reality-based models to better analyze, organize, and create reuse activities using virtual reality and a holographic collaborative experience. The instructional activity is also a pretext for demonstrating the potential of combining the 3D digital data fruition with additional data information, in virtual reality and holographic mode, for collaborative disciplinary investigations and interpretations in the process of knowledge, conservation, and reuse of the historic built heritage. The case study is Cornello dei Tasso (Bergamo, Italy). A little municipality on the old Via Mercatorum that birthed the Italian post system. Its morphology makes it ideal for testing and pushing the limits of virtual and holographic visualizations and interactions with the urban system conservation and enhancement project.For this reason, for some time now, within several master’s degree courses at the Polytechnic University of Milan, integrated classes in Survey and Built Heritage Preservation have been programmed that precisely encourage the learning and use of digital techniques for the knowledge and understanding of the existing built environment and as support for conservation, maintenance and reuse operations. One of the main unsolved issues in the digitalization pipeline regards the use by the practitioner of 3D data effectively and helpfully by making the most of the data completeness, immersivity of the tridimensional geometry, richness of detail, and accurate color.
