Visualising the incomplete. Virtual representation and fruition of two maiolica tiled floors in Palermo

The paper describes a research experience conducted on the maiolica floorings of the Oratories of the Bianchi and San Mercurio in Palermo. The study focuses on the analysis, documentation, and digital reconstruction of the drawing of the two floorings, which, due to various circumstances, have been severely damaged, compromising their original image. The research aims to develop a multimedia application using motion tracking to digitally experience the lost configurations. The process involved archival research, surveys using laser scanning and photogrammetric techniques, graphic analysis, and comparison with similar elements. The survey, thoroughly documenting the state of preservation of the flooring, allows for accurately relating the ‘reconstructed’ drawing to the ‘partial’ state of affairs. Starting from survey data, it is possible to obtain three-dimensional digital models that enable users to explore objects or environments digitally in detail. User movement can be tracked to provide an engaging and personalised experience. The multimedia motion tracking application, developed for the flooring of the Oratorio di San Mercurio, constitutes a form of virtual restoration, allowing the exploration of an imaginary context without direct physical interventions on the artifacts. In this way, virtual reconstruction becomes an integral part of the interpretation process of the flooring.
