Abstract

A pair of convex clusters are selected. Each convex cluster has a center of mass located at an original fixed distance from a common origin, and is oriented along a vector formed at a fixed angle from a common polar axis. A span is measured between the centers of mass of each convex cluster. A segment is measured from the center of mass of each convex shape to a point closest to the other convex shape along the span. A new fixed distance from the common origin for the center of mass for one of the convex clusters located along the vector for that convex cluster is evaluated if the span is less than the sum of the segments of the convex clusters. The pair of convex clusters are displayed rendered using at least the new fixed distance for the center of mass of the one convex cluster.

Claims

1. A system for providing a perspective-corrected representation of a multi-dimensional cluster rendering, comprising:

a comparison module measuring a span between centers for a pair of clusters, each center having an independent radius and being located in concept space at an independent distance along a vector drawn from a common origin and formed at an independent angle from a common axis drawn through the common origin; and

a distance determining module determining a perspective-corrected independent distance from the common origin for one such cluster if the span does not substantially equal the sum of the independent radii of the clusters, the perspective-corrected independent distance substantially equaling a root of a quadratic equation formed by the independent distances of the clusters and angle formed there between.
