Abstract
Abstract A three dimensional reproduction of an object is made by photographing the object at predetermined intervals by rotating the camera in a fixed plane 180° about a fixed axis which is at right angles to the plane of rotation. Each photograph is divided at a point perpendicular to the photograph and along the axis of rotation. Each photograph is then embedded in or affixed to a wedge shaped carvable material, the angle of the wedges being the same as the angle of rotation between photographs. The wedges are fitted together such that the dissected portions of each photograph meet each other at the common axis in a linear plane, and all wedges, when fitted together, form a 360° circle. The outlines of the photographed article in the composite of wedges represent substantially a three dimensional reproduction of the article. Each wedge, when carved along the outline, represented by the photograph, thus produces a substantially accurate three dimensional reproduction of the image photographed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
182 words
A method for the three dimensional reproduction of an image which comprises steps of: a. photographing the image at specified angles of rotation over 180° in a fixed plane about a fixed axis, b. dividing the photographs thus obtained at the axis of rotation into two separate parts, c. affixing each part of the divided photograph to a wedge shaped carvable material such that the side of the photograph forming the axis of rotation is at the pointed edge of the wedge, the angle of the wedge being the same as the angle of rotation between photographs, the wedge being made of such material that the outline of the photographed image is visible therein, d. assembling each wedge into place so that the points of the wedges meet at a common axis of rotation and the divided photographs meet in a linear plane such that a 360° representation in outline form of the image is presented in the assembled wedges, and e. carving each wedge along the outline of the photograph contained therein to obtain a three-dimensional reproduction of the image photographed.
Claim 2
Independent Claim
182 words
A method for the three dimensional reproduction of an image which comprises steps of: a. photographing the image at specified angles of rotation over 180° in a fixed plane about a fixed axis, b. dividing the photographs thus obtained at the axis of rotation into two separate parts, c. affixing each part of the divided photograph to a wedge shaped carvable material such that the side of the photograph forming the axis of rotation is at the pointed edge of the wedge, the angle of the wedge being the same as the angle of rotation between photographs, the wedge being made of such material that the outline of the photographed image is visible therein, d. assembling each wedge into place so that the points of the wedges meet at a common axis of rotation and the divided photographs meet in a linear plane such that a 360° representation in outline form of the image is presented in the assembled wedges, and e. carving each wedge along the outline of the photograph contained therein to obtain a three-dimensional reproduction of the image photographed.
Claim 3
Dependent Claim
30 words
A method for the three dimensional reproduction of an image according to claim 1 wherein the carvable material is selected from the group consisting of wax, wax-polymer mixtures and polymers.
Claim 4
Dependent Claim
27 words
A method for the three dimensional reproduction of an image according to claim 2 wherein the angle of rotation between photographs is between one and ten degrees.
Claim 5
Dependent Claim
27 words
A method for the three dimensional reproduction of an image according to claim 3 wherein the photographs are enlarged prior to being affixed to the carvable material.
Claim 6
Dependent Claim
