Digital 3D reconstruction for the multiscale investigation on the Drawing of the fortified wall of Turin

Abstract

[EN] The birth in Roman times, the development in the Baroque season and the massive Napoleonic demolition of the fortified wall of Turin constitute the phases of an event still clearly readable in the current urban fabric of the historical city center: the extant elements, even if portions of a highly fragmented layout, are punctual statements of an articulated pattern of superpositions, reconnections … Starting from the full bibliographic, cartographic and archival documentation, this contribute aims to actualize the numerous study schemes, drawn up over decades, anchoring their course, sketched by traces and additions, to the digital cartography. The goal is to construct a matrix from which it is possible to extrapolate thematic analysis oriented to survey and digital reconstruction of special items: city gates, bulwarks … The 3D representations could be used as a medium of interpretation and communication of the transformation, sedimentation and structuring of the urban form.
