6.7.6 NUBLBIC *(b, v) *

Creates a nurbs curve with 3 dimensional euclidian control points
which interpolates a vector of data points *v* by
Local Bicubic Interpolation. If the flag *b* is
not zero the algorithm is corner preserving, else corners are
smoothed.
*b* is a number node, and *v* is a typeless nodes to which the
data points are connected.

In the C++ class hierarchy the class created by the NUBLBIC keyword is derived
from a general nurbs curve class (see NURBCURV, 6.7.9),
so that it can be used at any places where a nurbs curve is expected
(with the same number format and control point type of course)

The following variations of this keyword exist (some of them
define the same internal structures, and are only defined to allow
consistent naming conventions):
