Projection mapping is a technique used to accurately project video content onto an irregular surface. This is often a 3D surface such as a building or car, however 2D surfaces can be projection mapped too.We have prepared a glossary of terms with definitions to help you understand video, lighting and audio jargon
The key to projection mapping is accuracy and to achieve this the object is often 3D modelled in computer CAD software first. If a 3D model is unavailable then a large complex object such as a gothic building may be laser-scanned with millimetre accuracy in order to create one. Video content is then created and applied to the 3D design. Media servers are often used to make the process easier to visualise and to program a show and the computer can calculate exactly where to position each pixel from multiple projectors.
The technique has become more and more common in the last few years with advertisers and big-budget shows utilising it to astonishing effect. It is possible to create unreal illusions of buildings physically changing shape and even being built or falling down it’s easy to see why.
