AddNurbsCurveList2 (X3DObject)

Description

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

Scripting Syntax

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

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 );

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

Return Value

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