RFNurbsSurface.GetHControlPoint

Description

Retrieves the homogeneous control point coordinate of the NURBS surface at the specified index location.

Syntax

Function RFNurbsSurface.GetHControlPoint(uIndex As Long, vIndex As Long, pPoint As RFHPoint) As RFErrorCode

The GetHControlPoint syntax has these parts:

Part	Description
uIndex	[IN] Long Required. Control point index of the NURBS surface in U parametric direction.
vIndex	[IN] Long Required. Control point index of the NURBS surface in V parametric direction.
pPoint	[OUT] RFHPoint Required. Homogeneous control point coordinate of the NURBS surface at the specified index location.

Remarks

Control points index in U parametric direction ranges from 0 to (the number of control points in U parametric direction - 1).
Control points index in V parametric direction ranges from 0 to (the number of control points in V parametric direction - 1).
