CurveGetLocalTangentPoint Method (Point3d, Double, Interval, Double)

Search for a location on the curve, near seedParmameter, that is tangent to a test point.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll)

Since: 6.0

Syntax

public bool GetLocalTangentPoint(
	Point3d testPoint,
	double seedParmameter,
	Interval subDomain,
	out double curveParameter
)

Public Function GetLocalTangentPoint ( 
	testPoint As Point3d,
	seedParmameter As Double,
	subDomain As Interval,
	<OutAttribute> ByRef curveParameter As Double
) As Boolean

Parameters

testPoint: Type: Rhino.GeometryPoint3d
The test point.
seedParmameter: Type: SystemDouble
A "seed" parameter on the curve.
subDomain: Type: Rhino.GeometryInterval
The sub-domain of the curve to search.
curveParameter: Type: SystemDouble
The parameter value at the tangent point

Return Value

Type: Boolean
True if a solution is found, false otherwise.
