Ricerc@Sapienza

Il volume raccoglie contributi il cui filo conduttore è la modellazione 3D e il BIM, con una divisione in tre sezioni: Il BIM per l'industria delle costruzioni; il BIM per la valorizzazione e gestione del patrimonio esistente; il 3D Modeling. Ogni sezione presenta le più recenti ricerche, progetti, realizzazioni, costituendo un punto di osservazione privilegiato sullo stato dell'arte del settore inn ambito italiano ed internazionale.

ICTs are today frequently used in the communication of cultural heritage. Among these Mixed Virtuality offers a visualization system on smart devices where, depending on the needs of dissemination, the reconstructions of objects and spaces can be viewed in Virtual Reality or Augmented Reality mode. As a case study, an application is proposed in the archaeological area of the Acropolis of Volterra.

Augmented Reality (AR) represents a growing communication channel, responding to the need to expand reality with additional information, offering easy and engaging access to digital data. AR for architectural representation allows a simple interaction with 3D models, facilitating spatial understanding of complex volumes and topological relationships between parts, overcoming some limitations related to Virtual Reality.

Il volume raccoglie i contributi dei ricercatori, dei professionisti e degli operatori del settore, sullo stato della ricerca nell’ambito del 3D Modeling &BIM. È interessante verificare come, analizzando le “Keywords” presenti nei contributi, siano presenti quelle più comuni e fondanti il tema, come i termini BIM, HBIM, 3Dmodeling, VR, AR, Interoperabilità.

Sometimes, the georeferencing of a cave in the global reference system can be challenging. Some difficulties may arise when narrow passages do not allow the use of classical topographic equipment or a terrestrial laser scanner. In these specific cases, the surveyor can employ a visual-based approach to produce both the followed path and the 3D model of the hypogeum. The report we are presenting is the result of a survey in the Guattari cave carried out using images taken by a Huawei P9 mobile phone and a Nikon D800E camera with a 16mm fisheye lens.

The survey of ancient cave can generally be performed by traditional topographic methods that allow also its georeferencing in a global
reference frame; some difficulties may arise when there are narrow tunnels that do not consent the use of a total station or a terrestrial
laser scanner. In such cases a visual-based approach can be used to produce, both the followed path and the 3D model of the hypogeal
environment. A prompt photogrammetric survey has been used to reconstruct the morphology of the La Sassa Cave, situated in the
