Abstract
Projection mapping is an expressive technology in which a video projector is used to projection images onto a three-dimensional “object” such as an architectural structure or sometimes a tree, moving person, etc., rather than a square screen. From a technological aspect, projection mapping is the process of creating the desired expression through a combination of conventional 3DCG technology, image processing technology and projection technology. This paper provides an overview of the relationship between projection mapping and conventional technologies, as well as a new workflow using a 3D printer.
