Od virtuálnej reality k reálnej virtuálite

3D planning gradually becomes the standard not only at the universities or research institutes, but in companies too. By the tools of the virtual reality new factories are planned, machines, as well as conveyors, transport systems, energy wiring etc., are located. A problem comes, when already existing construction is not 3D digitized, but only in 2D. Then often the 2D is transformed into3D, which is not accurate.
