Understanding projector mapping.
Projector mapping encompasses various terms, including video mapping and spatial augmented reality. The way in which this produces such unique displays, is the projection technology which turns, morphs or augments the primary image to cover an irregular shape, rather than a traditional square or rectangular surface area. Projector mapping can transform complex buildings and industrial landscapes into intricate art forms, which are used for publicity or background displays. Often technology allows for specialised software to turn a flat 2D image into a 3D or even 4D image – the surface area of a building can be used to create a multi dimensional spatial designs, thus mimicking or disguising the original environmental surface.
Problem with outdoor projector mapping.
The main challenge is finding hardware that can cope with the external weather conditions and as far as we have researched there is no other option but to put the hardware in an outdoor housing that protects the projector from the weather and possible theft. We found one company that seems to be the only manufacture of projector environmental housings who fits their ProEnc outdoor projector enclosure with high security locks. These provide all the protection needed and puts any installers mind at rest when deploying a multi thousand dollar projector in the outdoors.
Projector mapping is suitable for many applications:
• Products or Services
• Music Venues
• Large scale groups
Creating optical illusions is a very clever way of getting a product or service noticed. Graphics are highly complex and can incorporate text and audio-visual properties to provide a narrative. As technology evolves, this recent development has already taken the digital advertising world be storm. Since its infancy in the 1960, techniques it has crept quietly through development to the phenomenon it is today. Because of its scale and complex content, clients are put off using it, possibly because it looks expensive; therefore it must be, but not necessarily! A screen is not required because there is a ‘free’ building on which to display the image.
Buildings used in the past have included;
The Sydney Opera House in Australia
Bucking Palace. The Queen’s residence in London England
The festival Fête des Lumières in Lyon.
Disneyland’s Haunted Mansion ride
Big brand companies have embraced the use of projector mapping for digital advertising campaigns on a large scale for many years now. The chosen object is created as a complete physical replica, which is then videoed using specialist software by artists, who turn it into an image to be projected onto a surface. This ‘masks’ the exact shape or multiple shapes using templates. The image is ‘shaped’, without loosing detail , onto the designated building or surface area. Any man made construction or indeed natural spatial property is capable of hosting a projected image. From a branded training shoe, to a detailed front of a House of Worship, through to a 3 dimensional room with everyday objects. It is a virtual world of color, shape and design. The technical elements, for specialised technicians to work out is the X-Y-Z orientation of the image; and the position, distance and lense specification.
As a final note on this subject, projection mapping can also be interactive, as displayed by creating the illusion of a giant pinball machine, where people were able to interact with the game. So if you are wanting to cover any building for advertising, such as a night club, then projector mapping is the answer!
