Starting from the field of architecture and the nowadays widespread 3D digital design, the transfer of a problem to a digital world, which is infinite on directions and independent to realtime, its conditions and limitations, a start has been made towards a new era. From the moment, though, that the models are not in the physical world in which they are depended, it is difficult to understand completely the massive amount of information that are transferred and how would the corresponding images of the models be in the real world.This particular problem does not only show on the field of architecture, but also in other fields, like internal decoration, advertising, clothing industry, even in fields irrelevant to design like modern medicine.

Mapping Projection offers a solution to this problem, evolving even more in the abilities of digital media by transferring this private universe back to reality, thus offering the user a sense of interaction and experience during the course of the presentation. The name betrays the process of this technique, which is divided into the stages of Mapping, i.e. the analytical mapping of surfaces and the Projection, i.e. the projection of the desired image onto the previously mapped area. The user can operate the two stages, either in the manner described, or by any other technological or not media that he wants. There is thus created a new 4TH dimension in our reality where the visual map of the three dimensions, which consists of the views of the buildings and the surrounding environment, to the work and the details of the smallest object, giving its position to this parallel layer of optical reality.
