1. A system for reorienting clusters within a display, comprising:

  • a database to maintain clusters within a display, each cluster having a center located at a distance relative to a common origin for the display and a radius measured from the center;

    a reorient module, comprising;

    a comparison module to select a pair of the clusters based on their distances from the common origin, to determine a bounding region for each cluster in the pair by forming a pair of tangent vectors about the cluster and originating at the common origin, and to compare the bounding regions of the clusters in the pair; and

    a distance determination module to increase the distance from the common origin of one of the clusters in the pair upon overlap of the bounding regions as a perspective-corrected distance and to move the one cluster to reorient the cluster'"'"'s center at the perspective-corrected distance in the display, wherein the perspective-corrected distance is determined as a function of the distances and the radii of the clusters in the pair, and an angle between tangent vectors representing the distances of the clusters in the pair, anda processor to execute the modules.
