Abstract:
1. A structure for representing a visual pattern, the structure comprising: a plurality of tile elements held in a fixed relationship to one another, each of the tile elements representing a corresponding area of the visual pattern, each of the tile elements comprising a generally planar surface inclined at an inclination angle with respect to a reference plane, each of the tile elements having an orientation angle with respect to a reference direction, the orientation angle defined between projections, on the reference plane, of a line normal to the generally planar surface and a line parallel to the reference direction; and a substrate having a surface wherein the plurality of tile elements are coupled to the surface of the substrate; wherein the orientation angle of each tile element is determined by a brightness of the corresponding area of the visual pattern, wherein the tile elements representing areas of the visual pattern with different brightnesses have different orientation angles, wherein the tile elements reflect light incident thereon to present luminance characteristics which vary based on a viewing location of an observer, and wherein the substrate comprises an optical medium and each tile element comprises a region of interrupted transparency in the optical medium.
