La mappatura scientifica e gli approcci comunicativi nella ricostruzione virtuale del sito "Grotte di Catullo" mediante la metodologia Extended Matrix: il caso studio di e-Archeo 3D.

This contribution outlines the scientific mapping process of the virtual reconstruction model for the Roman archaeological site "Grotte di Catullo" (Sirmione, BS) and discusses communicative approaches in the e-Archeo 3D web app. This work is part of the broader e-Archeo project (Ministry of Culture, Ales S.p.A) and it focuses on the University of Verona's study of Roman villa in Sirmione. It provides a brief historical-architectural overview of the site and details the creation of a three-dimensional model and its scientific back-end. The methodology employed, known as Extended Matrix from CNR-ISPC, ensures transparency by linking reconstructed elements directly to the sources used for their validation. This scientific-mapped model was used as the basis for a photorealistic virtual reconstruction, carried out by Carraro LAB. The subsequent section describes the e-Archeo 3D web app, that offers three virtual navigation levels: the current site preservation view, a photorealistic virtual reconstruction, and a three-dimensional model with a scientific back-end. Different communicative modes for presenting these levels are discussed, considering narrative choices and user types. In summary, this contribution provides an overview of techniques and methodologies for virtual reconstruction, emphasizing the importance of scientific validity and transparent communication of research results.
