WebWhat is circle packing algorithm? Introduction. A circle packing is a configuration P of circles realizing a specified pattern of tangencies. As such, it enjoys dual natures—combinatoric in the pattern of tangencies, encoded in an abstract “complex” K, and geometric in the radii of the circles, represented by a radius “label” R.
