Projection mapping is a technology used to turn irregularly shaped objects into a display surface for projection. After the object is chosen or created, a virtual replica of the entire physical setup is created. A virtual model of the projection surface is created, and placed within a virtual environment. Coordinates need to be defined for where the object is placed in relation to the projector. Finally, the xyz orientation, position, and lens specification of the projector are adding to the virtual scene.
Video mapping first gained notoriety through guerilla advertising campaigns and video jockeys for electronic musicians. These advertising campaigns commonly used mapping techniques to project interactive scenes onto the sides of buildings. Common techniques for these performances included both 3-D mapping techniques and 3D projection to create the illusion of depth.
