Abstract
The aim of the paper is to study the characteristics of different 3D digital models (point clouds, mesh, CSG, BIM) for the realization of a museum of historical buildings widespread in the territory of South Tyrol through the 3D modeling of several farmhouses between the towns of Collalbo, Longomoso and Siffiano, in the Renon area. Therefore, moving from a defined case study, the paper proposes a workflow for model choice, use, and sharing considering also users profile. The objective is to create a system that allows, the sharing, both on site and remotely, of farmhouses digital models, information, images and documents found during the research. The purpose is to enhance the territory with the promotion of its knowledge taking into account also the importance of the participative aspects. In fact, in this system, are crucial and are a fundamental part of the safeguarding process, effectively increasing the information content and filling any information gaps, allowing the system to grow and become increasingly considerable and effective for the knowledge, documentation and enhancement of the territory.
