MeshClosestPoint Method (Point3d, Point3d, Vector3d, Double)

public int ClosestPoint(
	Point3d testPoint,
	out Point3d pointOnMesh,
	out Vector3d normalAtPoint,
	double maximumDistance
)

Public Function ClosestPoint ( 
	testPoint As Point3d,
	<OutAttribute> ByRef pointOnMesh As Point3d,
	<OutAttribute> ByRef normalAtPoint As Vector3d,
	maximumDistance As Double
) As Integer

Parameters

testPoint

Type: Rhino.GeometryPoint3d
Point to search for.

pointOnMesh

Type: Rhino.GeometryPoint3d
Point on the mesh closest to testPoint.

normalAtPoint

Type: Rhino.GeometryVector3d
The normal vector of the mesh at the closest point.

maximumDistance

Type: SystemDouble
Optional upper bound on the distance from test point to the mesh. If you are only interested in finding a point Q on the mesh when testPoint.DistanceTo(Q) < maximumDistance, then set maximumDistance to that value. This parameter is ignored if you pass 0.0 for a maximumDistance.

Return Value
