Documentation	A cone is a gridded surface given as a family of conic sections whose control points vary linearly. NOTE! A 5-point ellipse with all defining positions identical is a point. Thus, a truncated elliptical cone can be given as a 2x5 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, the a circular cone can be constructed using ((P1, P1, P1),(P2, P3, P4)). The apex most not coinside with the other plane.
