Set (NurbsSurfaceMesh) *

Description

Sets a NurbsSurfaceMesh from a complete data description of the mesh. This is only available from scripted operators. Note: If you use it on a object with some clusters and you change the topology the burden of updating the clusters is on the user. For non-scripted operators this property can only be set if the object has been frozen.

Scripting Syntax

NurbsSurfaceMesh.Set( Count, UVControlPoints, [NbUControlPoints], [NbVControlPoints], [UKnots], [NbUKnots], [VKnots], [NbVKnots], [UClosed], [VClosed], [UDegree], [VDegree], [UParam], [VParam], [NurbsFormat] )

C# Syntax

NurbsSurfaceMesh.Set( Object in_vsalCount, Object in_vsaUVControlPoints, Object in_vsaNbUControlPoints, Object in_vsaNbVControlPoints, Object in_vsadUKnots, Object in_vsaNbUKnots, Object in_vsadVKnots, Object in_vsaNbVKnots, Object in_vsabUClosed, Object in_vsabVClosed, Object in_vsalUDegree, Object in_vsalVDegree, Object in_vsaeUParam, Object in_vsaeVParam, siNurbsFormat in_eNurbsFormat );

Parameters

Parameter	Type	Description
Count	Long	Number of NurbsSurface in the mesh.
UVControlPoints	1D Array	The control points are stored in a 1 dimensional array. The array must contain the number of U control points, followed by the number of V control points, followed by the sequence of x,y,z,w values e.g. {NbU, NbV, Xo,Yo,Zo,Wo...X(n-1),Y(n-1),Z(n-1),W(n-1)}.
NbUControlPoints	Array of Longs	Specifies the number of U ControlPoints per NurbsCurve.
NbVControlPoints	Array of Longs	Specifies the number of V ControlPoints per NurbsCurve.
UKnots	Array of Doubles	An array of knot values in U direction.
NbUKnots	Array of Longs	Specifies the number of U Knots per NurbsCurve.
VKnots	Array of Doubles	An array of knot values in V direction.
NbVKnots	Array of Longs	Specifies the number of V Knots per NurbsCurve.
UClosed	Array of Boolean values	Specifies whether the nurbs surface is closed in U direction.
VClosed	Array of Boolean values	Specifies whether the nurbs surface is closed in V direction.
UDegree	Array of Longs	Degree of the nurbs surface in U direction.
VDegree	Array of Longs	Degree of the nurbs surface in V direction.
UParam	Array of siKnotParameterization values	The parameterization factor of the nurbs surface in U direction.
VParam	Array of siKnotParameterization values	The parameterization factor of the nurbs surface in V direction.
NurbsFormat	siNurbsFormat	Specifies how the data is formatted. Default Value: siSINurbs
