The contribution of the 3D study for new reconstructive proposals of Lecce in Roman age

This contribution concerns, in particular, the study of the two most important monuments of ancient Roman Lupiae: the amphitheater and the theater, whose remains, now incorporated in the modern urban fabric, can still be seen and visited only partially. Despite the evidence of the monumental ruins still visible, there is the impossibility for the visitor to perceive their actual size, both in plan and elevation. At the moment there are no information boards and didactic aids to understand the complete aspect of the two monuments how they could appear in ancient. The realization of accurate reconstructive proposals starting from the laser surveys, as well as the application of technologies that utilize Image- Based algorithms SfM (Structure from Motion), have been aimed at the realization of different outputs to facilitate the visit in situ of the two monuments, with different ways of reading. Applications of semi-AR in addition with stereoscopic narratives allow to understand the characteristics of architectural-construction not clearly understood, but rather to make readable reconstructions both within their original context, both superimposed over modern city. An approach useful to provide a sense of the scale of buildings. In this process of study, the contribution of 3D modeling software it is not confined to the pure generation and manipulation of polygons in the space, but it is crucial to facilitate the processes of interpretation.
