SubDEvaluateCurvature Method (SubDComponentParameter, SubDExtraordinaryVertexCurvature, SurfaceCurvature)

Evaluates the curvature of a point on this SubD's surface, choosing what to report exactly on an extraordinary vertex.

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

Parameters

parameter
Type: Rhino.GeometrySubDComponentParameter
The parameter to evaluate.
extraordinaryVertexCurvature
Type: Rhino.GeometrySubDExtraordinaryVertexCurvature
What to report when the parameter is exactly on an extraordinary vertex, where the limit surface has no curvature of its own.
curvature
Type: Rhino.GeometrySurfaceCurvature
The surface curvature is returned here, or null if this fails.

Return Value

Type: Boolean
True if the evaluation succeeded.
