HBIM: from survey to digital twin. The workflow of the case study of the tomb of the Medusa at the Policlinico Umberto I, Rome

The article presents the results of a study carried out on the “Tomb of the Medusa” located within the walls of the Polyclinic Umberto I of Rome, dating back to the Hadrian period (II sec. A.C).

The objectives pursued firstly analyze the use of the HBIM methodology and subsequently the elaboration of the restoration project with particular attention to the material elements and the study of degradation.

The interoperability of the entire design process allows to pass from the survey through acquisition and management of point clouds to the information of the parametric three-dimensional model via the use of BIM modeler, VPL (visual programming language) and free form modelers.

The result achieved by the entire workflow thus comes to the proposal of museum design interventions based on the use of virtual reality.
