Architectural mapping, façade projection, 3D projection videomapping, display surfaces, and architectural vj set are some of the definitions used for a new artistic format and a new technique that consists in projecting video images on buildings, façades, and other structures in public spaces (but also in theatres and museums) or on nearly any kind of complex surface or 3D object to shatter the viewer’s perception of perspective. The projector allows bending and highlighting of any shape, line or space. It creates astonishing optical illusions–a suggestive play of light that turns a physical object into something else by changing its perceived form. The context is that of so-called “augmented reality.”
The perceptual illusion, in the most successful cases of videomapping, is that of a “liquid architecture” which adheres as a film or mask over the concrete surface. Fragments of surfaces, as if they were Lego bricks, create an optical illusion of great impact for the audience, which no longer distinguishes between the real architecture and the virtual one. Immediately acquired by major international brands for advertising and the launch of new products, the technique also offers a glimpse of possible performative uses, which would allow combining video art, animation, installations, graphic art, light design, choreography and live theatre .
