AddSurface (NurbsSurfaceMesh) *

Description

Adds a surface to the mesh.

Scripting Syntax

    NurbsSurfaceMesh.AddSurface( [ControlPoints], [UKnots], [VKnots], [UClosed], [VClosed], [UDegree], [VDegree], [UParam], VParam, [NurbsFormat] )

C# Syntax

    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 );

Parameters

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. Default Value: siSINurbs

Return Value

NurbsSurface
