Detailed Description

Implementation of PlanarFigure representing a subdivision polygon (smooth curve).

A subdivision polygon uses iterative subdivision to produce a smooth curve from the control points. The number of subdivision rounds and a tension parameter control the smoothness of the resulting curve.

Inherits circumference and area features from PlanarPolygon. The polyline is generated by applying multiple rounds of subdivision to the control points.
