ABSTRACT:
The projection of a planar distorted pattern onto a three dimensional surface provides a true or undistorted pattern on that surface. Complex patterns are applied to an irregular or curved surface by a method which includes the formation of a graphics display of the body on a computer graphics display and conversion to a two dimensional CADAM data base containing a planar projection of the pattern intended for application to the curved surface. This pattern information is translated into other forms, such as the form of a numerically controlled milling machine tape or photo mask, which is then used by ancillary method apparatus to form the desired pattern as a part of the method. The process describes the construction of a dichroic parabolic RF reflector.
