NurbsSurfaceMesh.AddSurface
Adds a surface to the mesh.
NurbsSurface NurbsSurfaceMesh.AddSurface( Object in_vsaControlPoints, Object in_vsadUKnots, Object in_vsadVKnots, Boolean in_bUClosed, Boolean in_bVClosed, Int32 in_lUDegree, Int32 in_lVDegree, siKnotParameterization in_eUParam, siKnotParameterization in_eVParam, siNurbsFormat in_eNurbsFormat ); |
oReturn = NurbsSurfaceMesh.AddSurface( [ControlPoints], [UKnots], [VKnots], [UClosed], [VClosed], [UDegree], [VDegree], [UParam], VParam, [NurbsFormat] ); |
| Parameter | Type | Description |
|---|---|---|
| ControlPoints | 1D or 3D Array | The control points used for creating the nurbs surface. The control points can be stored in a 1 dimensional array or in a 3 dimensional matrix (UxVx4) of x,y,z,w values. The 1 dimensional array should contain the number of points in U and V at the beginning followed by a sequence of x,y,z,w values e.g. {U,V,Xo,Yo,Zo,...X(uv-1),Y(uv-1),Z(uv-1),W(uv-1)}. |
| UKnots | Array of Doubles | A vector of knot values in the U direction. |
| VKnots | Array of Doubles | An array of knot values in the V direction. |
| UClosed | Boolean | Specifies whether the nurbs surface is closed or not in U direction. |
| VClosed | Boolean | Specifies whether the nurbs surface is closed or not in V direction. |
| UDegree | Long | Degree of the nurbs surface in U direction. |
| VDegree | Long | Degree of the nurbs surface in V direction. |
| UParam | siKnotParameterization | The parameterization factor of the nurbs surface in U direction. |
| VParam | siKnotParameterization | The parameterization factor of the nurbs surface in V direction. |
| NurbsFormat | siNurbsFormat | Specifies how the data is formatted.
