The NurbsSurfaceData type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | NurbsSurfaceData |
Copy constructor.
|
Methods
| Name | Description | |
|---|---|---|
 | Create |
Construct NurbsSurfaceData based on NURBS surface data, where the weights are supplied.
The NURBS surface will be (piecewise) polynomial if all the weights are equal, rational if not.
Note: A rational polynomial is a quotient of two polynomials; this includes a polynomial,
which can be thought of as a quotient with denominator equal to 1.
|
| Dispose | Releases all resources used by the NurbsSurfaceData |
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| GetControlPoints |
Get the list of control points.
|
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetKnotsU |
Get the list of knots in the u-direction.
|
| GetKnotsV |
Get the list of knots in the v-direction.
|
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetWeights |
Get the list of weights.
|
| IsValid |
Check if the object contains a valid NurbsSurfaceData.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Properties
| Name | Description | |
|---|---|---|
 | DegreeU |
The degree of the spline in the u-direction.
|
| DegreeV |
The degree of the spline in the v-direction.
|
| IsRational |
Tells if the spline is rational or not.
If it is true (rational), then the NURBS is a piecewise rational polynomial function.
If it is false (non-rational), then the NURBS is a piecewise polynomial function.
|
| IsValidObject |
Specifies whether the .NET object represents a valid Revit entity.
|
| ReverseOrientation |
If true, the surface's orientation is opposite to the canonical parametric orientation, otherwise it is the same.
The canonical parametric orientation is a counter-clockwise sense of rotation in the uv-parameter plane.
Extrinsically, the oriented normal vector for the canonical parametric orientation points in the direction of
the cross product dS/du x dS/dv, which S(u, v) is the parameterized surface.
