The utility of the application of new three-dimensional technologies for the study and dissemination of heritage from a historical-technical perspective: case studies

In this article we analyse the different applications of convergent photogrammetry in three different cases. In the first one, the application in the beginning of a restoration project of the Chapel of the Purification in the Church of the Carmine in Milan (Italy), where we will explain the usefulness of this technology. In the second case the utility of the three-dimensional reproduction made to the hidden murals at the Collegiate Church of Santa Maria in Daroca (Spain) for its diffusion and finally the application of this technique as a tool for communicating the results of research in projects. The confrontation of these cases in which the same technology is applied at various stages of the process of conservation and study of heritage, with distinctly different purposes, aims both to deepen their usefulness, such as delineating its limits and requirements.
