X3DObject.AddNurbsCurveList2

Description

Creates a NurbsCurveList object. This is typically used for creating a nurbs surface from a set of geometry data.

C# Syntax

X3DObject X3DObject.AddNurbsCurveList2( Object in_vsalCount, Object in_vsaControlPoints, Object in_vsaNbControlPoints, Object in_vsadKnots, Object in_vsaNbKnots, Object in_vsabClosed, Object in_vsalDegree, Object in_vsalParam, siNurbsFormat in_eNurbsFormat, String in_bstrName );

Scripting Syntax

oReturn = X3DObject.AddNurbsCurveList2( Count, ControlPoints, [NbControlPoints], [Knots], [NbKnots], [Closed], [Degree], [Parameterization], [NurbsFormat], [Name] );

Return Value

Returns a X3DObject object holding the new geometry; the new X3DObject is parented under this X3DObject.

Parameters

Parameter Type Description
Count Long Number of curves.
ControlPoints 2D Array The control points are stored in a 2-dimensional array. The array is 4 x (number of U ControlPoints)
NbControlPoints Array of Longs Specifies the number of ControlPoints per NurbsCurve. Optional if there's only one NurbsCurve.
Knots Array of Doubles An array of knot values.

Default Value: Knots derived from control points.

NbKnots Array of Longs Specifies the number of Knots per NurbsCurve. Optional if there's only one NurbsCurve.
Closed Array of Boolean Specifies whether the nurbs curve is closed .

Default Value: False

Degree Array of Longs Degree of the nurbs curves.

Default Value: 3

Parameterization Array of siKnotParameterization The parameterization factor of the nurbs curve.

Default Value: siNonUniformParameterization

NurbsFormat siNurbsFormat Specifies how the data is formatted.

Default Value: siSINurbs

Name String name of object
