NurbsKnot

Description

Returns the specified knot in a NURBS curve or surface.

For NURBS curves, index1 corresponds to the segment of the curve to be queried, and index2 corresponds to the knot in the segment.

For NURBS surfaces, index1 corresponds to the u- or v-direction of the surface (u=1, v=0), and index2 corresponds to the knot index.

The index is zero based (0 to number of knots - 1).

PROCEDURE NurbsKnot(
				objectHd : HANDLE;
				index1   : LONGINT;
				index2   : LONGINT;
				VAR knot : REAL);

def vs.NurbsKnot(objectHd, index1, index2):
    return knot

Name	Type	Description
objectHd	HANDLE	Handle to NURBS curve or surface.
index1	LONGINT	Segment of curve to be queried (NURBS curve), or direction (NURBS surface).
index2	LONGINT	Index of segment or direction knot.
knot	REAL	Knot value.

this function will work for both nurbs curves and nurbs surfaces
