Polynomial

The base radius of curvature and the conic constant are not used by this surface model. The sag of the polynomial surface is given by

z = γ 1 x 2 + γ 2 x 4 + γ 3 x 6 + γ 4 x 8 + γ 5 y 2 + γ 6 y 4 + γ 7 y 6 + γ 8 y 8

A more general polynomial surface is also available, see "Extended Polynomial".
