Knowing All About Projection Mapping Projection mapping is also called video mapping or spatial augmented reality and which refers to a form of projection technology wherein a specialized software installed in a computer converts an image into either a 2D or 3D graphic by spatially mapping this image on a virtual program, as if to video mimic the natural environment, and from this, the virtual 2D or 3D graphic image is sent to the video projector, that is attached to the computer, and which displays this virtual image to a blank space, such as building facades and walls or in small indoor objects or theater stages, like a moving video scene. This new technology is specially used by many advertisers and artists for expressing their art into this new medium, such that they enhance the virtual, projected image by adding extra dimensions into it or using optical illusions or notions of movements and combined any of these with audio music to create an audio-visual narrative. There were two historical events when projection mapping was first introduced, one debuted in 1969 in the Haunted Mansion ride of Disneyland, wherein the ride used fake disembodied head objects, which were projected in a 16 mm film projector, making them appear animated, and followed in 1980, when artist Michael Naimark filmed people interacting with objects, in which he projected this film in the room wall, creating illusions as if the people interacting with the objects were really there in the room. Projection mapping is conducted following these steps: first, an object which will be projected is either chosen or created through a video; second, a specialized software installed in the computer will be used to spatially map the corners of the created video with the chosen object in it, so the video can cover the entire space, which have been selected as the display area; third, using an opacity template to mask the exact shapes and positions of the different parts of the display area; fourth, a 3D mapping technique is used to define the coordinates so that the object is placed in relation to the lens specification of the projector, such that 20,000 lumens for large projectors are used, such as for city skyscrapers or for small scale projection, a 2,200 lumens is adequate for theater projections.
What Do You Know About Projections
Because of projection mapping technology, many people are benefiting from it, using it as follows: advertising campaigns for well-known products in major cities across the world, such that through projection mapping, campaign scenes are projected onto the sides of buildings; video jockeys for electronic musicians which is becoming common for DJs to accompany their music with a synced visuals; artists use their avant garde form of art into projection mapping, such that they can show their art work in any location using any space as their canvas; advocates use projection mapping as their medium of activism by video displaying their advocacy in a chosen building site; and this technology is frequently used by Disney in their Imagineering department.What Do You Know About Projections
