public class PgSurface_ConicType

extends PgSurfaceDescr

Parametrized surface given by method, or interactively, by function expressions. If the functions of a surface are specified in calc_f method and, later, interactively edited, then the interactive expressions are further used. This is important for evaluation of higher order differentials since they are only approximated using finite differences in the later case.
