what is projection mapping? (which also called video mapping or spatial augmented reality.)
well…by mapping the contours and surfaces of objects, artists and techies can project animations onto them and create the illusion that they are being transformed. The objects can be complex architectural cityscapes or simpler abstract forms . The technique is used by artists and advertisers alike who can add extra dimensions, optical illusions, and notions of movement onto previously static objects and varied surfaces. Brands and events companies are increasingly using the technology for stunts that will go on to create an online presence buzz.
