RFNurbsSurface.CreateApproximatedSurface

Description

Creates NURBS surface by approximating the points.

Syntax

Function RFNurbsSurface.CreateApproximatedSurface(uDegree As Long, vDegree As Long, uNewPtsCount As Long, vNewPtsCount As Long, bClosed As Boolean, uPtsCount As Long, vPtsCount As Long, pPts As RFPoint3) As RFErrorCode

The CreateApproximatedSurface syntax has these parts:

Part	Description
uDegree	[IN] Long Required. Degree of NURBS surface in the U parametric direction. It should be set to 2 in this version.
vDegree	[IN] Long Required. Degree of NURBS surface in the V parametric direction. It should be set 2 in this version.
uNewPtsCount	[IN] Long Required. Number of target control points in the U parametric direction after the approximation.
vNewPtsCount	[IN] Long Required. Number of target control points in the V parametric direction after the approximation.
bClosed	[IN] Boolean Required. It determines whether NURBS surface is closed or not.
uPtsCount	[IN] Long Required. Number of points to interpolate in the U parametric direction.
vPtsCount	[IN] Long Required. Number of points to interpolate in the V parametric direction.
pPts	[IN] RFPoint3 Required. The first element of RFPoint3 array containing points to interpolate.

Remarks

Approximating points should be in the order of forwarding direction of parameterization as follows.

pPts (0) = Approximating Point (0,0)
pPts (1) = Approximating Point (0,1)

pPts (Vn - 1 ) = Approximating Point (0, Vn - 1)
pPts (Vn) = Approximating Point (1,0)

pPts (Un X Vn - 1) = Approximating Point (Un - 1, Vn - 1 )

where, Un = the number of approximating points in U parametric direction.(= uPtsCount)
Vn = the number of approximating points in V parametric direction. (=vPtsCount)
Approximating Points (i,j) = i'th in U parametric direction and j!/th in V parametric direction approximating point.
With bClosed = TRUE option, the resulting NURBS surface has same start point and end point.
