In 1400 Filippo Brunelleschi developed a drawing system of the space: the perspective.
Today architects and engineers don’t use pencils and leafs to draw a perspective more, but now the perspective is created by computer, so it isn’t a two-dimensional drawing. Today the space “can be browsed” by particular architectural software. New digital technologies have changed the communication language of the architecture, that it has always been united with images and drawings. Today it’s possible to create a building with its colours and its material before its construction through a professional software.
