Patent ID: 7593829

Claim:
A method for generating a pseudo-random pattern of dots to be patterned on a surface, the method comprising the steps of: Receiving surface input parameters for the surface having a known shape including at least one curved surface at a programmable processor, wherein the surface input parameters mathematically describe the known shape with reference to a known coordinate system; Selecting dot locations for the pseudo-random pattern of dots for at least a portion of the surface based on the surface input parameters by executing software at the programmable processor, wherein the pseudo-random pattern is a pattern that incorporates a randomness that overlays a systematic structure, wherein non-overlapping cell areas completely cover the surface, wherein one dot location is randomly selected anywhere within a respective one of at least a portion of the non-overlapping cell areas, so that there is no more than one dot patterned in any one of said portion of non-overlapping cell areas; and outputting coordinates for dot centers based on the dot locations from the programmable processor.
