Projection mapping, similar to video mapping 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, small indoor objects or theatrical stages.
In this very simple example, the pink "paint", writing and highlights were all projected onto this ordinarily plain white bus.
This gave the production company great flexibility as the bus starts out plain white at the beginning and changes as the story plays out. It would obviously be too impractical to have the cast use real paint!
Projection mapping usually requires the set pieces (e.g. a bus, a flat, or proscenium arch, etc.) to be spiked and fixed, and assured that when these items are brought onto the stage, they are at the exact same spot so the projector will hit the target accurately.
Ideally, the mapping process should be done at the venue if this is possible. It may be possible for us to do mapping based on photographs of the pieces, with precise dimensions supplied.
