The project deals with some experimentations related to the use of digital video projections on architectural mock-up models, aimed at enhancing and promoting architectonic cultural heritage. A mock-up video projection enable to augment architectural trivial and non-trivial models, on various scales and for different purposes. These ways involve digital video projectors and architectural scaled models to create light exhibits without the use of mobile or through screen devices. More specifically, this project outlines a scientific-technological framework regarding tools and procedural protocols to set up spatial projection based augmented reality applications.
