Adds a trimmed surface to the mesh.
oReturn = NurbsSurfaceMesh.AddSurfaceWithTrim( [ControlPoints], [UKnots], [VKnots], [UClosed], [VClosed], [UDegree], [VDegree], [UParam], [VParam], [NurbsFormat], [NbTrim], [IsBoundary], [ProjectionType], [NbCurve], [CurveControlPoints], [CurveNbControlPoints], [CurveParam], [CurveKnots], [CurveNbKnots], [CurveDegree], [CurveClosed] ); |
| 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.
Default Value: false |
||||||
| VClosed | Boolean | Specifies whether the nurbs surface is closed or not in V
direction.
Default Value: false |
||||||
| UDegree | Long | Degree of the nurbs surface in U direction.
Default Value: 3 |
||||||
| VDegree | Long | Degree of the nurbs surface in V direction.
Default Value: 3 |
||||||
| UParam | siKnotParameterization | The parameterization factor of the nurbs surface in U
direction.
Default Value: siNonUniformParameterization |
||||||
| VParam | 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 |
||||||
| NbTrim | Long | Specifies how many trims this surface contains.
Default Value: 0 |
||||||
| IsBoundary | Array of Booleans | Specifies whether each trim is a boundary. | ||||||
| ProjectionType | Array of Longs | Specifies the projection type of each trim. Each member of the
array maps to a single trim, so the array is actually a combination
of the possible values (0 and 1).
|
||||||
| NbCurve | Array of Longs | Number of nurbs curves in each trim | ||||||
| CurveControlPoints | 2D Array of 2D Array | Array where each set of control points is stored in a 2-dimensional array. The array is 4 x Number of ControlPoints. | ||||||
| CurveNbControlPoints | Array of Array of Longs | Specifies the number of ControlPoints per NurbsCurve per trim. | ||||||
| CurveParam | Array of Array of siKnotParameterization values | The parameterization factor of the nurbs curve for each trim. | ||||||
| CurveKnots | Array of Array of Doubles | An array of knot values for each trim. | ||||||
| CurveNbKnots | Array of Array of Longs | Specifies the number of Knots per nurbs curve per trim. | ||||||
| CurveDegree | Array of Array of Longs | Degree of the nurbs curves for each trim.
Default Value: 3 |
||||||
| CurveClosed | Array of Array of Booleans | Specifies whether the nurbs curve is closed for each trim.
Default Value: False |
