OPEN SOURCE PLATFORM FOR 3D MODELS

We have created an open-source platform that allows researchers to manage and analyze 3D data and to store and organize the different phases of the building reconstruction, including its architectural elements and decorations. It is accessible through username and password, and all its information can be easily updated and shared.

The system implements two different representation models: Point cloud and 3D mesh. Therefore, the user can work with the model that better suits the analysis in progress and use actual data without the need for post-production.

The scan points are organized hierarchically based on the indications given by the working team, with specific categories for the new structures and restorations. In order to create the 3D model, the points align with each other and are georeferenced by relative coordinates. Once converted to a mesh, the model is used to:

• create supports for findings’ storage and conservation;
• generate a 1:1 scale model and integrate the damaged parts;
• create supports for the application of the restored elements.

The computer reconstruction instantly compares the real and virtual models. For instance, for the ceiling restoration, we matched the pre- and post-collapse models of the coffering, with its elements and geometries highlighted on a superimposed layer.

The platform allows sharing the documentation produced according to Building Information Modeling (BIM) systems, based on a participative model focused on data exchange.

The project was selected by HBIM (Smart Heritage Building Performance Measurement for Sustainability), which studies methods for intelligent performance measurement in historic buildings, such as the impact on sustainability and the effects on the building’s health after its reconstruction.
