Method and system for recording a viewing point

A method for recording a point in space, which is to be used as a viewing point from which an eye will view a subject, said view being monocular, so as to render visual perception two-dimensional, the viewing point being recorded in such a way as to allow the eye to be returned to the viewing point if the position of the eye is changed, the method comprising:

• (a) designating each reference point, of a first pair of reference points, by use of at least a first graphic form, said first graphic form being included in a first surface of an apparatus for designating reference points;
• (b) designating each reference point, of a second pair of reference points, by use of at least a second graphic form, such that said first pair of reference points is located between said second pair of reference points and the eye, said second graphic form being included in a second surface of said apparatus for designating reference points, wherein said first surface and said second surface are structurally connected to each other;
• and
• (c) positioning said graphic forms such that, when seen from the viewing point, each of said reference points of said first pair of reference points appears to be superimposed on said reference points of said second pair of reference points.
