Scan-to-HBIM Approach for Digital Management and Virtual Fruition

ng and outputs, jointly oriented toward documentation and dissemination, constitutes the topic of this contribution. Starting from a reality-based survey, an as-built model was developed and applied to the case study of the Fountain of the 99 Cannelle, validated according to the criteria of the Level of Accuracy (LOA) and enriched through a material–chromatic mapping of the surfaces, derived from photogrammetric data. This mapping is intended to make phenomena of decay and traces of intervention immediately legible, while at the same time increasing the informational density of the model. The model was then integrated into real-time visualization environments, in which it can also be explored and interrogated in immersive mode, making it an excellent support for collaborative processes of data management and sharing. In this regard, the results show how the controlled integration of textures within the HBIM workflow makes it possible to produce, in a coordinated manner, outputs for documentation and enhancement, facilitating access to information, including for non-specialist users; however, critical issues remain related to scalability and the complexity of texture management in these environments.
