BIM, Virtual and Augmented Reality for citizen involvement in the evaluation of the urban transformation

The knowledge of the urban pattern and of the rules that over time have led the cities’ transformation cannot be separated from the representation of individual building artefacts that make up the structure of the urban fabric. Geometry is an inalienable means to manage the spatial expression of a drawing and to efficiently and properly display it according to strictly proven rules. It is also an unequivocal speculative instrument for the investigation of the form and for the comprehension of its structure, from two-dimensional to three-dimensional of reality, from sign to meaning, from project to object.
