ACQUISITION AND INTERACTIVITY OF 3D REPRESENTATION CONNECTED WITH THE VIRTUAL HERITAGE

The research that is proposed concerns the experimentation, applied to case studies, of modern methodologies and software of interactive representation with the possibility of employment in the professional and cultural field. The work focuses on the definition of a workflow that relates the three-dimensional photogrammetric techniques with automatic retopology methods and transfer on a virtual RTR platform. Specifically, the study is aimed at a precious artefact on the Appia Antica in Rome, and eventually extendable to a virtual museum path along the consular road: the Sepulcher of the Festoons and that of the Frontispice of the late Republican era, first half of the 1st cent. BC Along the fourth mile, the majority of the tombs is little more than a mass of bricks eroded by time, with the exception of the Tomb of the Festoon, an example of "Ara tomb" that incorporates, in reduced forms, the typology of the altar for sacrifices. The Superintendency decided to maintain the structure given to the tombs by Luigi Canina during the nineteenth-century restorations, integrating only the gaps created with the wear and tear of time. The ultimate aim is to create a prototype of an immersive virtual museum, explored through interactive tours through the help of virtual headsets and controllers such as Oculus Rift and HTC_VIVE. The research is therefore part of the theories on digital cloning, digital crafting and virtual migration, proposing to offer, through three-dimensional graphic informatics models, the possibility of generating environments and artifacts similar to the real ones in a non-existent space, completely configurable in function of the archaeological museum dissemination.
