CurveClosestPoint Method (Point3d, Double, Double) |
Finds the 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.

)
Public Function ClosestPoint (
testPoint As Point3d,
<OutAttribute> ByRef t As Double,
maximumDistance As Double
) As Boolean
Parameters
- testPoint
- Type: Rhino.GeometryPoint3d
Point to project. - t
- Type: SystemDouble
parameter of local closest point returned here. - maximumDistance
- Type: SystemDouble
The maximum allowed distance.
Past this distance, the search is given up and false is returned.
Use 0 to turn off this parameter.
Return Value
Type:
Booleantrue on success, false on failure.
