    Abstract: A system includes a computer generated hologram (CGH) design plane and a processor capable of representing a three dimensional object. The processor is configured to represent a surface of the three dimensional object by a facet, impose a grid defining a set of nodes upon the facet, and associate object points with each node of the grid. The processor is further configured to orient the facet to include a common global origin in the CGH design plane and displace the object points away from their associated node in a random or pseudo random direction parallel to the CGH design plane.

    Abstract: A thermosetting powder coating composition according to the present invention comprises as binder a co-reactable particulate mixture of a carboxylic acid-functional polyester component and a curing agent having groups reactive with carboxylic acid groups, characterized in that the carboxylic acid-functional component comprises a semi-crystalline polyester having an acid value of from 10 to 70 mg KOH/g and a hydroxy value of no more than 11 mg KOH/g. Generally the semi-crystalline polyester has one or more Tg values less than 55° C., a sharp melting point of 50 to 200° C. and preferably a number average molecular weight of at least 1600. The composition may, if desired, include an amorphous polyester and the curing agent may be, for example, an epoxy resin or a bis(beta-hydroxyalkylamide).
