X3DObject.AddNurbsCurve
Creates a NurbsCurveList object composed of one curve. This is typically used for creating nurbs curves from a set of geometry data.
X3DObject X3DObject.AddNurbsCurve( Object in_ControlPoints, Object in_Knots, Boolean in_bClosed, Int32 in_lDegree, siKnotParameterization in_Parameterization, siNurbsFormat in_eNurbsFormat, String in_bstrName ); |
oReturn = X3DObject.AddNurbsCurve( ControlPoints, [Knots], [Closed], [Degree], [Parameterization], [NurbsFormat], [Name] ); |
This method returns the X3DObject parent of this new geometry, the new X3DObject is parented under this X3DObject.
| 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.
Default Value: Knots derived from control points. |
| 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 |
| Name | String | name of object |
