Abstract
Abstract. The paper deals with an interdisciplinary research activity aiming at developing a digital and integrated tool able to collect several data concerning the cultural heritage, and to manage and communicate them to a wide community. The small church of San Menna, located in the hamlet with same name in the municipality of Lucoli not so far from L’Aquila city, was the object of the research. The church has been chosen for its historical significance, its architectural peculiarity and for the valuable artworks that it preserves. Based on a photogrammetric model of the church, also used for the remote analysis of cultural asset (planimetric and evolutionary hypotheses, three-dimensional stratigraphic analysis, etc.) a virtual word usable in Virtual Reality (VR) has been developed. The VR setting allows the accessibility of a digital semantic model with information that can be activated with special interactive hotspots (images, texts and audio), which are able to provide an immersive and all-encompassing experience to the tourist. The potentialities of the same tool in the context of diagnosis and conservation process related to cultural heritage in seismic areas, such as those of the Abruzzi Apennines, have also been investigated through the integration of forms concerning the significant features of the artistic assets surveyed in the construction.
Highlights
1.1 3D modelling and cultural heritageThe field of cultural heritage has been strongly renewed due to the use of recent and new digital technologies
The use of digital technologies, including those of Information and Communication Technology (ICT), in the field of cultural heritage has allowed the development of highly detailed threedimensional digital models, which support the enhancement of the heritage thanks to the possibilities provided by several software of virtual reality that allow the remote use of the assets located on a territory
The workflow developed by the research team for the study case of the San Menna church in Lucoli, which begins from geometric survey of the artefact to arrive at the use of contents structured through the Cardboard technology launched in 2014 by Google, integrating different low cost technologies, represents a process that our team has in common with other research groups (Maiellaro et al, 2018; Bozzelli et al, 2019; Rahamana et al, 2019)
Summary
The field of cultural heritage has been strongly renewed due to the use of recent and new digital technologies. The implementation of digital models that accurately illustrate the cultural heritage, allow to have digital archives in which qualitative information, concerning the conservation state and the history of an artefact, are combined with quantitative information, related to the geometry of building elements These correlation between information allows to define: specific and planned analyses, such as the drafting of investigation surveys and the realization of maintenance interventions, promoting the conservation (Marra et al, 2019); new ways to approach culture, making the user no more a simple spectator but a dynamic actor able to interact and interface with cultural heritage (MiBAC, 2019; Bettio et al, 2015; Trizio et al, 2019b). In addition to the valuable fresco, a seventeenth century altar, placed at the back of the nave added, hides another wonderful artwork ascribed to Pompeo Cesura, another major exponent of Abruzzi culture and Raffaello Sanzio’s follower (fig. 2), and currently visible from the central altarpiece
