Patent number: 5284536Abstract: A method of fabricating model trees and plants for decorating a diorama. The model is made from stacking foliage disks on a telescoping dowel, which functions as an imitation trunk. First, an outline of leaves and branches is drawn within a panel on paper. Next, the outline is shaded in to obtain a silhouette thereof. Numerous foliage disks can be clustered on a single panel to conserve space and to facilitate mass production. The silhouette is photographed to obtain a reverse image. Then through photolithography and etching, a metal template of the reverse image is made. The template is overlaid on a wood veneer having a kraft paper backing, and is laser cut. After laser cutting, each foliage disk can be separated from the veneer sheet. An assembly hole is provided in each foliage disk to facilitate attachment to the dowel. In an alternative embodiment, the trunk can be fashioned from braided wire with one end that is unraveled and flared outwards.Type: GrantFiled: August 13, 1991Date of Patent: February 8, 1994Inventor: Michael I.

The liner and second layer portion of deposition material thereon are removed. A second mask is placed over the remaining support portion of the first mask and sprayed with deposition material therein. Then the liner portion of the second mask and deposition material therein are removed. This process is repeated until the three dimensional article is formed. Then the mask support portions surrounding the article are removed from the article.Type: GrantFiled: October 10, 1991Date of Patent: April 20, 1993Inventors: Fritz B. Prinz, Lee R. Weiss, Duane A.

A series of color profiles are made along one side of the sheet material in sequence, each color profile corresponding in shape and color to the shape and color of a different cross-section of the surface to be constructed. A coating of a pressure sensitive adhesive is then applied to one side of the sheet material. Areas on the sheet material outside of the profiles are then removed and discarded so as to leave a series of unconnected planar elements, each planar element having an edge shape or outline corresponding to a cross-section of the surface with the color profile itself forming at least a color border or margin on the surface of its respective planar element around the edge. The planar elements are then stacked one on top of the other in proper alignment and sequence and individually laminated together to produce the desired three-dimensional surface.Type: GrantFiled: December 27, 1988Date of Patent: May 14, 1991Inventor: Norman F.

Patent number: 4534813Abstract: Flat pattern equivalents for curved surfaces may be generated by developing a regular network of quadrilateral grid elements resembling a fish net which is mathematically smoothed onto the curved surface. Surface features such as boundaries and cutouts are mapped onto the network. The network is then transformed onto a flat mapping plane to form a grid in a manner analagous to smoothing a fish net mesh onto a flat surface. The surface features are then transformed to the flat surface grid.Individual plies or parts are then cut based upon the flat patterns. The plies or parts will conform to the curved surface exactly.Type: GrantFiled: July 26, 1982Date of Patent: August 13, 1985Assignee: McDonnell Douglas CorporationInventors: Robert D.

Patent number: 4255033Abstract: Conventional cameras and other optical instruments produce images upon one plane only. Objects at differing ranges from the lens of such cameras cannot appear upon that plane in-focus simultaneously, and the operator, hence the viewer, is obliged to choose one primary plane of interest in which the major subject lies; all other objects at other ranges will be out of focus.The invention described produces photographic images that are in-focus at all ranges.This is achieved by dividing the original scene into two or more images focussed upon different ranges, and eliminating from each image those parts that are out-of-focus. The remaining in-focus parts of each image are then reconstituted into a single image for presentation.The elimination of blurred parts may be done by comparison of one sub-image with another, or by the subjective intervention of an operator using a mathmatical support system.The images described may be applied to still or motion photography, film or electronic.Type: GrantFiled: February 23, 1979Date of Patent: March 10, 1981Inventor: Gordon M. Rose

Patent number: 3988520Abstract: 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.degree. 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.degree. 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.Type: GrantFiled: October 6, 1975Date of Patent: October 26, 1976Inventor: Marlene A.
