Abstract

Description of the three-dimensional scenic space design process F. Moran Mariano Garcia Abril 5, Valladolid47014, Spain The Roman architect Vitrubio, who lived in the 2nd century, described in his fifth book of architecture how the Greeks and Romans introduced on stage in their theatres three triangular prisms in which they painted the scenes corresponding to the three acts in which every classic play is divided. Turning over its own axis, the representation of the three different settings appeared successively placed on the faces of three triangular prisms . Nowadays ,this system has been used again in an innovative way, by means of the multiplication of prisms to make advertising placards which show three different aspects.
