Abstract
In the last few years in Italy the scientific community has increasingly focused its interest on the documentation of Cultural Heritage. The evolution of relief and modeling technologies combined with an outstanding variety of software and hardware available on the market and online has allowed an increasing number of operators to produce three-dimensional models, to elaborate new reflections, studies and popular products. In the archaeological relief field, after an early preponderance of laser tools, interest has recently shifted towards photogrammetric tools, with a switch from stereo-photogrammetry to bundle reconstruction through commercial and open source software available online. In the field of Building Archaeology, the technological evolution has allowed us to continually set new goals, from the increasingly detailed three-dimensional recording of buildings, to the representation of realistic models of the construction phases and the demolition of the buildings over time. This article attempts to illustrate, through the presentation of some projects of the Laboratory of Building Archaeology of the University of Siena, the ‘mental structure’ existing before the material one, that is behind the recording of the construction characteristics of a building, by focusing on the factors that are at the base of the choice of a particular survey system and on the consequent possibilities in generating and managing three-dimensional models.
