Representing geometry shape and matter of a complex façade: the church of San Placido in Catania

Abstract

This study investigates the potentialities, the limits and the advantages of the 3D model obtained by means of 3D laser scanner for the documentation and the geometric, formal, materic stdudy of an historical complex façade such as the one of the eight-century church of san Placido in Catania. The aim is also to detect possible protocols useful for 3D modeling and data management. The carried out elaborations have absorbed the research team in the exploration of the subsequent 3D digital models which represent, each one with its own feature, the geometry and the measure, the shape and the matter.
