Abstract
Abstract A process generates and displays representations of various entities--solid objects, scenes, graphs, lines, and points--in true three dimensional space (3D) space. A series of segments of thin transparent film are marked with respect to reference elements of the film segments to correspond to a series of sections of an entity. The segments are assembled spaced apart in corresponding sequence in an apparatus for display, aligned therein by their reference elements, and illuminated by a diffuse substantially uniform light source at one end of the sequence. The assembly of marks on the film segments can be seen from the other end of the sequence by transmitted light as a three dimensional representation of said entity. Apparatus and film segments have unique features accomodating the process of this invention.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
171 words
A process for producing a representation in three dimensional space of an entity which comprises the steps of, marking positively each of a series of segments of thin transparent film to correspond to each of a series of sectional portions of said entity so that similar markings on any segment in said series of segments have similar brightness, assembling said segments in association with display means in a sequence corresponding to the sequence of sectional portions of said entity and holding said segments flat, spaced apart, substantially smooth and parallel to each other in coaction with said display means, illuminating said sequence of segments with light transmitted through said segments from one end of said sequence from a diffuse substantially uniformly bright distributed light source at least coextensive in area with a segment at said one end of sequence, presenting the assembly of marks of said segments to be viewed from the other end of the sequence by transmitted light from said source as a three dimensional reconstitution of said entity.
Claim 2
Dependent Claim
171 words
A process for producing a representation in three dimensional space of an entity which comprises the steps of, marking positively each of a series of segments of thin transparent film to correspond to each of a series of sectional portions of said entity so that similar markings on any segment in said series of segments have similar brightness, assembling said segments in association with display means in a sequence corresponding to the sequence of sectional portions of said entity and holding said segments flat, spaced apart, substantially smooth and parallel to each other in coaction with said display means, illuminating said sequence of segments with light transmitted through said segments from one end of said sequence from a diffuse substantially uniformly bright distributed light source at least coextensive in area with a segment at said one end of sequence, presenting the assembly of marks of said segments to be viewed from the other end of the sequence by transmitted light from said source as a three dimensional reconstitution of said entity.
Claim 3
Dependent Claim
41 words
A process as described in claim 1 wherein said step of assembling said series of segments is reversible, whereby said segments can be removed from said display means and replaced by different series of segments for the display of different entities.
Claim 4
Dependent Claim
65 words
A process as described in claim 1 wherein said step of assembling said series of segments is reversible, and further including the steps of, removing select segments from said assembly, altering the markings on said select segments, reinserting said segments in said assembly, whereby alteration for correction of a three dimensional representation of an entity or adjustment to alteration of said entity can be effected.
Claim 5
Dependent Claim
161 words
A process for producing a representation in three dimensional space of an entity which comprises the steps of, marking each of a series of segments of thin transparent film with respect to prescribed fiducial markings similarly located on said segments to correspond to each of a series of sectional portions of said entity, assembling said series of segments in association with display means in a sequence corresponding to the sequence of sectional portions of said entity, and holding said segments substantially smooth, parallel to each other and spaced apart in correspondance in depth with said sectional portions and capable of transverse displacement, and the step of aligning each segment systematically and accurately by its fiducial markings with respect to said fiducial markings of other segments by displacement for optical coincidence whereby the assembly of marks on said series of segments can be exhibited as a three dimensional reconstitution of said entity systematically aligned independently of the nature of the subject markings.
Claim 6
Dependent Claim
161 words
A process for producing a representation in three dimensional space of an entity which comprises the steps of, marking each of a series of segments of thin transparent film with respect to prescribed fiducial markings similarly located on said segments to correspond to each of a series of sectional portions of said entity, assembling said series of segments in association with display means in a sequence corresponding to the sequence of sectional portions of said entity, and holding said segments substantially smooth, parallel to each other and spaced apart in correspondance in depth with said sectional portions and capable of transverse displacement, and the step of aligning each segment systematically and accurately by its fiducial markings with respect to said fiducial markings of other segments by displacement for optical coincidence whereby the assembly of marks on said series of segments can be exhibited as a three dimensional reconstitution of said entity systematically aligned independently of the nature of the subject markings.
Claim 7
Dependent Claim
41 words
A process as described in claim 4 wherein said step of assembling said series of segments is reversible, whereby said segments can be removed from said display means and replaced by different series of segments for the display of different entities.
