Technological hybridization for the fruition of cultural heritage. Architectural Perspectives of Andrea Pozzo at St. Ignatius in Rome.

The survey techniques based on photo acquisition have nowadays regained importance thanks to three main aspects related to technological innovations: the cheapness of production of digital images; the evolution of capacity to compute, memorize and share data; the consequent development of recursive algorithms on massive data. In the last years many experimentations have been conducted on the acquisition of this data, but the way to display and communicate them - both for scientific and simply informative aims - is still uncertain and not sufficiently investigated. The experimentation we want to illustrate here concern the opportunity to realize an interactive and multimedia informative system of an architectural or archeological space, based on a progressive fruition of several multi-thematic spherical panoramas. The activities of study, experimentation and test have involved both technological aspects and communication problems, at the different levels of representation, fruition, interaction and characterization. The quality of the realized model and its structuration in an easily shareable format allow to investigate the properties in order to increase the knowledge of it, also in a remote way. The case study of our experimentation concern the paintings by Andrea Pozzo at St. Ignatius in Rome.
