AN INFORMATIVE CONTENT 3D MODEL FOR THE HALL HOLDING THE RESURRECTION OF CHRIST BY PIERO DELLA FRANCESCA MURAL PAINTING AT SANSEPOLCRO, ITALY

Abstract. The Resurrection of Christ by Piero della Francesca (about 1460) at Sansepolcro (Italy) is a masterpiece in the development of painting. The painting is located in a hall of the city government building, which today holds the Civic Museum of Sansepolcro. This mural painting was realized on a brick wall (15 cm thick) located in a different place as it is today. Shortly later, the painting was moved by means of a transport to solid-wall and placed against a pre-existing wall (60 cm thick), where it is today, erecting against this wall a counter wall (15 cm thick) where the mural painting wall-panel (225 × 200 cm) had been inserted.

Within the studies aimed at restoration and conservation of the painting, the type and characteristics of the walls of the museum hall and of the wall where the painting is located have been defined through different types of diagnostic surveys. Geometric, physical, mechanical and material data from surveys are knowledge that must be archived and made accessible for future maintenance operations. Building Information Modeling (BIM) is a valid methodology that allows to build a three-dimensional database in which to collect information about diagnostics and conservation of the historical building. The aim of this paper is digitalization through the HBIM methodology of the hall of Resurrection, in order to create a “3D informative model” that describes the geometry with objects linking them the information related to knowledge of cultural heritage and it can represent a technical and organizational support for future conservation operations.
