Curve.ClosestPoint Method (Point3d, Double)

CurveClosestPoint Method (Point3d, Double)

Finds parameter of the point on a curve that is closest to testPoint. If the maximumDistance parameter is > 0, then only points whose distance to the given point is <= maximumDistance will be returned. Using a positive value of maximumDistance can substantially speed up the search.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 5.0
Syntax
Copy
public bool ClosestPoint(
	Point3d testPoint,
	out double t
)
Public Function ClosestPoint ( 
	testPoint As Point3d,
	<OutAttribute> ByRef t As Double
) As Boolean

Parameters

testPoint
Type: Rhino.GeometryPoint3d
Point to search from.
t
Type: SystemDouble
Parameter of local closest point.

Return Value

Type: Boolean
true on success, false on failure.
