6.7.2 NUBGAC (p, n, v)

Creates a nurbs curve with 3 dimensional euclidian control points which approximates a vector of data points v by Global Approximation. p is the degree and n the number of control points that the calculated curve shall have.

p and n are number nodes, and v is a typeless nodes to which the data points are connected.

In the C++ class hierarchy the class created by the NUBGAC 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):

Keyword	numbers
NUBGAC	float
NUBGAC_F	float
NUBGAC_D	double
NUBGAC_F_E3	float
NUBGAC_D_E3	double
