A method for color conversion applying minimal surface theory to the formation of the volumes in a three-dimensional color cube. Volume center points on the color cube are selected as entries in a color look-up table, and these center points are plotted on the color cube. Spheres centered about each volume center point are created, and the discrete locations in the color cube falling within each sphere are associated with the CLUT entry corresponding to that volume center point. The radii of the spheres are incrementally increased, and the discrete locations falling within the enlarged spheres are associated with the corresponding CLUT entry. As the spheres enlarge they begin to intersect. The intersection of the spheres form planes which divide the discrete locations such that each discrete location is associated with the closest volume center point. |
