AbstractThe analysis of freeform surfaces requires them to be reduced to more regular geometric structures. One approach is to approximate fragments of the given surface by quadrics, then use the points, lines, and planes defined by the quadric as bases for measurements. The present work describes a series of experiments designed to assess the stability of points defined in this way on human facial features. Both positive and negative findings are discussed.
