A N-D Virtual Notebook About the Basilica of S. Ambrogio in Milan: Information Modeling for the Communication Of Historical Phases Subtraction Process

Abstract

This essay describes the combination of 3D solutions and software techniques with traditional studies and researches in order to achieve an integrated digital documentation between performed surveys, collected data, and historical research. The approach of this study is based on the comparison of survey data with historical research, and interpretations deduced from a data cross-check between the two mentioned sources. The case study is the Basilica of S. Ambrogio in Milan, one of the greatest monuments in the city, a pillar of the Christianity and of the History of Architecture. It is characterized by a complex stratification of phases of restoration and transformation. Rediscovering the great richness of the traditional architectural notebook, which collected surveys and data, this research aims to realize a virtual notebook, based on a 3D model that supports the dissemination of the collected information. It can potentially be understandable and accessible by anyone through the development of a mobile app. The 3D model was used to explore the different historical phases, starting from the recent layers to the oldest ones, through a virtual subtraction process, following the methods of Archaeology of Architecture. Its components can be imported into parametric software and recognized both in their morphological and typological aspects. It is based on the concept of LoD and ReverseLoD in order to fit the accuracy required by each step of the research.

The Integration of a Scan-to-Hbim Process in Bim Application: The Development of an Add-in to Guide Users in Autodesk Revit

“…In recent years, the growing need to improve the management and conservation of the built heritage has led to the development of interesting studies in the field of HBIM (Kuo et al 2018) (Fai et al 2014) (Tucci & Bonora 2011). Innovative methods in the field of digitisation of the built heritage have underlined the need to orientate BIM applications also for heritage artefacts (Stanga et al 2017). Starting from the assumption that each building has its own morphological and typological peculiarities, the use of reality capture data (point cloud data) has further highlighted the inadequacy of BIM libraries oriented solely to the creation of simplified models.…”

Generative Modeling, Virtual Reality and Hbim Interaction: Immersive Environment for Built Heritage: Case Study of Shaikh Isa Bin Ali House, Bahrain

“…The second step required the use of novel Scan-to-BIM modeling requirements. GOG 9 and GOG 10 have shown great flexibility for transforming point cloud data into BIM objects during the last few years b) (Stanga et al 2017).…”

A Content-Based Immersive Experience of Basilica of Sant'ambrogio in Milan: From 3d Survey to Virtual Reality

“…Recent studies have shown how the intangible and tangible values of detected heritage artifact can be shared and transmitted to different professionals and users with high levels of detail (LOD) and contents (LOI), going beyond the simple 2D representation and the simple use of BIM objects and BIM libraries developed for new buildings (Ortega et al, 2015;Statham, 2019). Thanks to previous researches (Banfi et al, 2019;Stanga et al, 2017), the presented paper offers a new virtual environment, based on the use of 'informative models', that communicates the 'hidden' values collected during the last few years of one of the most important monuments in Milan: the Basilica of Sant'Ambrogio.…”
