- 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>>.
