【 摘 要 】

The latest information technology developments in the field of digital heritage (DH) have enabled the creation of novel virtual experiences favouring information-sharing connected to the 3D digital reconstruction of historical and existing buildings. In recent years, Building Information Modelling for historic buildings (HBIM) projects are the most applied methods to transmit the richness of built heritage from both the geometrical and informative points of view, but they are not always adequate to ensure a simple reading of different type of information for not-expert users. For this reason, further investigations were performed, following a novel SCAN-to-BIM process based on novel Grades of Generation (GOG 9 and 10) in order to digitally represent one of the most complex structure of the Basilica of Sant’Ambrogio in Milan. It is composed of arches supported by pillars, characterised by a double-wave curve, both on its vertical and horizontal axis. The information coming from the previous studies, such as historical documentation, as-found drawings, building archaeology analysis (materials and brick surface texture) and decay data (crack patterns, material discontinuity), was integrated with a novel webimmersive solution able to display 360° pictures, video and HBIM simultaneously. A detailed comparison of the 360 multimedia data of the current arrangement with the one of the HBIM historical phases allow experts and not-experts to analyse the transformation of the arch structures in a new immersive environment with different devices such as laptops, mobile phones and latest virtual and augmented reality (VR-AR) headset.
