The paper presents a methodological framework for the digital documentation, modeling, and dissemination of Cultural Heritage Routes within the H2020 PROMETHEUS project. It integrates multi-scale digital survey techniques (TLS, UAV photogrammetry, mobile scanning) with HBIM modeling and database construction to create structured digital replicas of heritage sites. These models are connected within virtual platforms to enable extended accessibility, supporting both analysis and public engagement. XR technologies (AR and VR) are employed to enhance storytelling, interactive exploration, and design scenarios, allowing users to visualize historical transformations and future redevelopment proposals. The approach emphasizes the creation of interoperable, multi-layered information systems linking geometry, metadata, and cultural narratives across territorial, urban, and architectural scales.
Tactile and Digital Narratives for a Sensitive Fruition of Bas-Relief Artworks
This paper investigates how digital technologies can support inclusive and multisensory museum narratives through the case of Donatello’s pulpit in Prato. Triggered by the temporary loan of two original relief panels to international exhibitions, the project developed a hybrid strategy combining digital documentation, tactile replicas, and augmented reality experiences to compensate for their absence and enrich visitor engagement. The research employed integrated image-based and range-based survey methods, including photogrammetry, terrestrial laser scanning, and structured-light scanning, to generate accurate 3D databases of the original parapet and its external copy. These datasets were used to produce orthophotos, high-resolution visual reproductions, and full-scale 3D printed tactile panels that visitors could touch and explore. Additional AR applications allowed users to visualize the missing reliefs in color and place digital models in external environments through mobile devices. The study demonstrates how digital replicas can become interpretative tools rather than mere copies, improving accessibility, participation, and heritage education while preserving the authenticity of the original artwork.
