Il ruolo dei modelli digitali 3D nell’analisi e nella rappresentazione di un’architettura rupestre. il caso studio della chiesa rupestre di S. Lucia alle Malve a Matera

Three-dimensional digital models – obtained using laser scanners ToF and digital photogrammetry – expand the ways in which it is possible to document and study a rupestrian architecture, also by implementing unprecedented analysis paths and renderings. The study presented is part of a series of theoretical/practical experimentations, conducted by the Architectural Survey Laboratory of the Department of Civil Engineering (University of Calabria), with the aim of investigating the capabilities and potential of these models in the rupestrian architecture field. The case study under consideration is represented by the rupestrian church of St. Lucia alle Malve in Matera. This structure was acquired by laser scanner ToF and digital photogrammetry, to obtain synthetic and detailed 3D models, which constitute, at the same time, a precious digital document and a powerful cognitive interface of the work. Starting from these 3D models, a series of figurative devices were created to describe the overall structure of the church, investigate the rocky surface to identify traces of processing, analyze the transformations and document the frescoes.
