AddNurbsSurfaceMesh2 (X3DObject)

Description

Creates a NurbsSurfaceMesh object. This method can be used for creating a mesh of multiple nurbs surfaces from a set of geometry data.

Scripting Syntax

X3DObject.AddNurbsSurfaceMesh2( Count, ControlPoints, [NbUControlPoints], [NbVControlPoints], [UKnots], [NbUKnots], [VKnots], [NbVKnots], [UDegree], [VDegree], [UClosed], [VClosed], [UParam], [VParam], [NurbsFormat], [Name] )

C# Syntax

X3DObject X3DObject.AddNurbsSurfaceMesh2( Object in_Count, Object in_ControlPoints, Object in_vsaNbUControlPoints, Object in_vsaNbVControlPoints, Object in_uKnots, Object in_vsaNbUKnots, Object in_vKnots, Object in_vsaNbVKnots, Object in_bUClosed, Object in_bVClosed, Object in_lUDegree, Object in_lVDegree, Object in_uParameterization, Object in_vParameterization, siNurbsFormat in_eNurbsFormat, String in_bstrName );

Parameters

Parameter

Type

Description

Count

Long

Number of surfaces.

ControlPoints

3D Array

The control points are stored in a 3-dimensional array. The array is 4 * (Max Number of V ControlPoints for a NurbsSurface) * (Total Number of U ControlPoints)

NbUControlPoints

Array of Longs

Specifies the number of U ControlPoints per NurbsCurve. Optional if you have only one NurbsCurve.

NbVControlPoints

Array of Longs

Specifies the number of V ControlPoints per NurbsCurve. Optional if you have only one NurbsCurve.

UKnots

Array

A vector of knot values in the U direction.

Default Value: Knots derived from control points.

NbUKnots

Array of Longs

Specifies the number of U Knots per NurbsCurve. Optional if there's only one NurbsCurve.

VKnots

Array

A vector of knot values in the V direction.

Default Value: Knots derived from control points.

NbVKnots

Array of Longs

Specifies the number of V Knots per NurbsCurve. Optional if there's only one NurbsCurve.

UDegree

Array of Longs

Degree of the nurbs surface in U direction.

Default Value: 3

VDegree

Array of Longs

Degree of the nurbs surface in V direction.

Default Value: 3

UClosed

Array of Boolean

Specifies whether the nurbs surface is closed or not in U direction.

Default Value: False

VClosed

Array of Boolean

Specifies whether the nurbs surface is closed or not in V direction.

Default Value: False

UParam

Array of siKnotParameterization

The parameterization factor of the nurbs surface in U direction.

Default Value: siNonUniformParameterization

VParam

Array of siKnotParameterization

The parameterization factor of the nurbs surface in V direction.

Default Value: siNonUniformParameterization

NurbsFormat

siNurbsFormat

Specifies how the data is formatted.

Default Value: siSINurbs

Name

String

name of object

Return Value

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