## Package vgp.surface.common Description

Parametrized surfaces given by Java functions, 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.
