Returns the number of knots for the referenced NURBS curve or surface. If the object is a curve, then index indicates the segment of the curve to consider. If the object is a surface, then the index indicates the U direction (for index = 1) or the V direction (for index = 0).
FUNCTION NurbsNumKnots(
objectHd : HANDLE;
index : LONGINT): LONGINT;def vs.NurbsNumKnots(objectHd, index):
return LONGINT| Name | Type | Description |
|---|---|---|
| objectHd | HANDLE | Handle to NURBS curve or surface. |
| index | LONGINT | Index of curve, or U/V choice for surface. |
/this function will work for both nurbs curves and nurbs surfaces. returns the number of knots for the indexed piece of the given nurbs curve. or number of U knot vector (index=1) or V knot vector (index=0) of the given nurbs surface
