NurbsCurveList.AddCurve operator

Description

Add a curve to the end of the curve list

Scripting Syntax

oReturn = NurbsCurveList.AddCurve( ControlPoints, [Knots], [Closed], [Degree], [Parameterization], [NurbsFormat] );

Return Value

NurbsCurve

Parameters

Parameter Type Description
ControlPoints 1D or 2D Array The control points used for creating the nurbs surface. The control points can be stored in a 1 dimensional array or in a 2 dimensional matrix (Ux4) of x,y,z,w values. The 1 dimensional array should contain a sequence of x,y,z,w values e.g. {Xo,Yo,Zo,...X(n-1),Y(n-1),Z(n-1),W(n-1)}.
Knots Array of Doubles An array of knot values.
Closed Boolean Specifies whether the nurbs surface is closed or not in U direction.

Default Value: False

Degree Long Degree of the nurbs surface in U direction.

Default Value: 3

Parameterization siKnotParameterization The parameterization factor of the nurbs surface in U direction.

Default Value: siNonUniformParameterization

NurbsFormat siNurbsFormat Specifies how the data is formatted.

Default Value: siSINurbs
