Creates a NurbsCurveList object. This is typically used for creating a nurbs surface from a set of geometry data.
oReturn = X3DObject.AddNurbsCurveList2( Count, ControlPoints, [NbControlPoints], [Knots], [NbKnots], [Closed], [Degree], [Parameterization], [NurbsFormat], [Name] ); |
Returns a X3DObject object holding the new geometry; the new X3DObject is parented under this X3DObject.
| 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 |
