Public Function ClosestParameter ( 
	testPoint As Point3d,
	<OutAttribute> ByRef longitudeRadians As Double,
	<OutAttribute> ByRef latitudeRadians As Double
) As Boolean

testPoint

Type: Rhino.Geometry.Point3d
Point to project onto the sphere.

longitudeRadians

Type: System.Double
The longitudinal angle (in radians; 0.0 to 2pi) where the sphere approaches testPoint best.

latitudeRadians

Type: System.Double
The latitudinal angle (in radians; -0.5pi to +0.5pi) where the sphere approaches testPoint best.

Type: Boolean
true on success, false on failure. This function will fail if the point it coincident with the sphere center.
