Projection Mapping, also known as Video Mapping, is a projection technology used to turn objects, often irregularly shaped, into a display surface for video projection. These objects may be complex industrial landscapes, such as buildings. By using specialized software, a two or three dimensional object is spatially mapped on the virtual program which mimics the real environment it is to be projected on. This way, the computer knows exactly where to project its information as it can bend and highlight any shape or form. Almost any surface can be used to ‘become a dynamic video display of 2D and 3D images that can transform what is reality for the audience into illusions and images of infinite possibilities’. Using this information, the software can interact with a projector to fit any desired image onto the surface of that object. This technique is used by artists and advertisers alike who can add extra dimensions, optical illusions, and notions of movement onto previously static objects. The video is commonly combined with, or triggered by, audio to create an audio-visual narrative.
