MeshClosestPoint Method (Point3d, Point3d, Double)

Gets the point on the mesh that is closest to a given test point.

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

Since: 5.0

Syntax

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

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

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

Type: Int32
Index of face that the closest point lies on if successful. -1 if not successful; the value of pointOnMesh is undefined.
