1. In a digital processing system operable to generate synthetic images, the improvement comprising: selecting a rank-1 lattice in accordance with a maximized minimum distance function (max-min-dist lattice) corresponding to points in the synthetic image to be generated; calculating pixel values in accordance with the selected rank-1 lattice; and generating a display-controlling electronic output signal based on the calculated pixel values, wherein the electronic output signal is operable to enable the display of the synthetic image on a display screen.
