SubDEvaluateCurvature Method (SubDComponentParameter, SurfaceCurvature)

Evaluates the curvature of a point on this SubD's surface.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 9.0
Syntax
Copy
public bool EvaluateCurvature(
	SubDComponentParameter parameter,
	out SurfaceCurvature curvature
)

Parameters

parameter
Type: Rhino.GeometrySubDComponentParameter
The parameter to evaluate.
curvature
Type: Rhino.GeometrySurfaceCurvature
The surface curvature is returned here, or null if this fails.

Return Value

Type: Boolean
True if the evaluation succeeded.
Remarks
Unlike the overload that returns the two principal curvature values, this one also reports their directions. See CreateFromSubD(SubD, SubDComponentParameter) for when the curvature exists.
