6.7.7 NUBLBIS *(b, m)*

Creates a bicubic nurbs surface with 3 dimensional euclidian control points
which interpolates a matrix of data points *m* 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 *m* is a typeless node to which the rows of the matrix of data points
are connected.

In the C++ class hierarchy the class created by the NUBLBIS keyword is derived
from a general trimmed nurbs surface class (see TNURBSURF, 6.7.22),
so that it can be used at any places where a trimmed nurbs surface 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):
