Scan-To-BIM-To-VR Processes for the Documentation and Valorization of the Defensive Fortifications in Piombino

The paper intends to explore the integration between Scan-to-BIM parametric modelling techniques and VR virtual systems to support activities of documentation, analysis, valorization, and popular storytelling of Architectural Heritage. In this sense, these themes have been deepened through a series of experimental HBIM applications conducted on the military fortifications of Piombino, and more specifically, on the case study of the defensive complex formed by the Rivellino and the Porta a Terra. Through the implementation of the HBIM model within game-engine platforms, the project aims at enhancing the historical heritage, favouring dissemination and interactive use through immersive virtual environments.

Multisensory VR Experiences Based on Auralization and HBIM. The Teatro del Maggio in Florence

The paper presents an HBIM-based workflow for the development of multisensory virtual reality experiences integrating architectural visualization and acoustic auralization. Starting from laser scanner surveys and Nurbs-based 3D modeling, the research develops an HBIM digital twin enriched with material and acoustic metadata to simulate the sound behavior of theatrical spaces. The methodology combines TLS acquisition, semantic segmentation of architectural elements and materials, acoustic parameter classification, BIM data enrichment, and interoperability with Unreal Engine for immersive VR experiences. Through plugins and sound simulation systems, the virtual environment reproduces both the visual and acoustic perception of the theater, enabling users to interactively experience the architectural and acoustic heritage of the venue.
