Game engine for Cultural Heritage: New opportunities in the relation between simplified models and database

Game engines can be regarded as powerful tools in the Cultural Heritage domain, not just as dissemination tools, but for managing the urban context in real time. This case-study is based on the ongoing project of Pietrabuona Castle (Pescia, Italy). It is an interesting example of a stratified historical centre, the conservation and promotion of which might benefit from using a new, integrated survey and alphanumeric data management tool. The method used to survey this medieval fortification had to provide both local institutions and researchers with an interactive tool encompassing several features of Cultural Heritage: from technical (decay, maintenance, environmental risks, etc.) to cultural (urban standard, historical understanding, immaterial features). Due to the cross-disciplinary nature of the ongoing project, we decided to share some major points of our investigation with the scientific community, in particular those concerning our procedure: the opportunity to use interactive applications to display themes of urban settlements as 3D models, based on a survey by laser scanner.
