Projection or video mapping is a special type of AR technology (augmented reality), creating an optical illusion between the actual surface of the building to which it is projected and its virtual version. This technology creates a wonderful artistic effect and unusual movements on the surface.

Using specialised software, a three-dimensional subject is mapped to a virtual programme that mimics the real environment to which it is projected. This technology is popular among artists and advertisers adding optical illusions and motion illusion of static objects and buildings. Video mapping is usually accompanied by sound which provides a true audiovisual story.

The video is available here, but it is more beautifull from the square – see you there?
