The 3d printer as a distinct media can realize digital operation into analog object. Therefore it is the perfect tool for our aim. Considering this, we are also interested in the abstraction of the printed result, that automatically appears while printing. (Due to the small resolution of the model and the visible plastic layers, created by the printhead) | The 3d printer as a distinct media can realize digital operation into analog object.

== | ==The Principle of the Zoetrope== | ||
To transform digital animation into analog animation there are several ways. | |||
The classical way is to expose film material frame by frame with the single shots of the animation until you have a complete copy of the movie. (e.g. for cinema movies) This form of analogisation is not suitable for our aims, cause only the carrier media is analog and real. The animation itself is a virtual image. Besides it is impossible to catch the full range of the 3rd dimension with this method, cause the film image itself is only a two dimensional copy. | |||

Therefore we have decided to use a very old optical technique, which was invented in 1834 by William George Horner: the zoetrope. | |||
A zoetrope basically a film sequence, arranged as a 360° panorama, that rotates infront of the viewers eyes. By the use of rotation the animation phases are arranged like a film. But the human eye can see the animation only with the help of a so called shutter. (otherwise the eye is too slow) The shutter in fact, is a kind of image interupter. The enables the slow human eye to perceive the animation through a quick change between image and darkness. (it lowers the framerate of the film by blocking the sight on the rotation with black phases) | |||
