“Projection Mapping uses everyday video projectors, but instead of projecting on a flat screen (e.g. to display a PowerPoint), light is mapped onto any surface, turning common objects of any 3D shape into interactive displays. More formally, projection mapping is “the display of an image on a non-flat or non-white surface”. _PMC (Now Lightform)
