What is video mapping or mapping projection?
Video Mapping is also known as video projection and spatial augmented reality, 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. 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.
\\\Projection mapping first came to prominence through guerilla advertising campaigns and video jockeys for electronic musicians.Large companies such as Nokia, Samsung and BMW have since used video projections to create campaigns for their products in major cities across the world. These advertising campaigns commonly use mapping techniques to project scenes onto the sides of buildings. Artists who are solely visual also use projection mapping as a means of creative expression, believing that it can enhance existing creative mediums such as painting and drawing.
