public interface Cone
extends GriddedSurface

A gridded surface given as a family of conic sections whose control points vary linearly. A 5-point ellipse with all defining positions identical is a point. Thus, a truncated elliptical cone can be given as a 2×5 set of control points

<<P1, P1, P1, P1, P1>, <P2, P3, P4, P5, P6>>.

P1 is the apex of the cone. P2, P3, P4, P5, and P6 are any five distinct points around the base ellipse of the cone. If the horizontal curves are circles as opposed to ellipses, then a circular cone can be constructed using <<P1, P1, P1>, <P2, P3, P4>>.
