X3DObject.AddNurbsSurfaceMesh2
Creates a NurbsSurfaceMesh object. This method can be used for creating a mesh of multiple nurbs surfaces from a set of geometry data.
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 ); |
oReturn = X3DObject.AddNurbsSurfaceMesh2( Count, ControlPoints, [NbUControlPoints], [NbVControlPoints], [UKnots], [NbUKnots], [VKnots], [NbVKnots], [UDegree], [VDegree], [UClosed], [VClosed], [UParam], [VParam], [NurbsFormat], [Name] ); |
Returns the X3DObject object holding the new geometry; the new X3DObject is parented under this X3DObject.
| 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 |
