The Scuola Grande di San Marco in Venice between architecture and perspective reliefs: restitutions and applications of advanced fruition

Abstract

The aim of the research was to investigate the facade of the Scuola Grande di San Marco in Venice through terrestrial photogrammetry and the procedures of perspective reversal, as well as digital representation and modeling. This investigation was conducted with particular interest in spatial reconstruction of the architectural elements defined in the perspective elevations.
The selection of photogrammetric methodology has permitted the acquisition of geometric data pertaining to the building that, in certain instances, are challenging to infer.
In addition to the projections and moldings of the Renaissance decorative apparatus, an orthogonal photographic mosaicking has been obtained that returns a planar projection of the main facade. The photogrammetric study was conducted in the lower portion of the elevation, where the illusionistic reliefs are situated. The reconstructions of these portions subsequently permitted the restoration of the plan and elevation in relation to the scene imagined in the marble perspectives, as well as the further three-dimensional modelling.
The integration of advanced sensing applications, perspective restitution, and digital representation of architecture enables the development of models that can be translated into augmented or virtual reality applications and physical-tactile replicas. These models can be utilized in a wider range of contexts, according to the specific needs of different categories of public (e.g., age, education, culture, disability, etc.).
They can serve as effective tools for dissemination and communication.
