Returns all Natural Neighbors corresponding to the query point.

[Visual Basic .NET]
Public Sub QueryNaturalNeighborIndices ( _
    ByVal pPoint As IPoint, _
    ByVal pNodes As ILongArray _
public void QueryNaturalNeighborIndices (
    IPoint pPoint,
    ILongArray pNodes
HRESULT QueryNaturalNeighborIndices(
  IPoint* pPoint,
  ILongArray* pNodes


pPoint [in]

  pPoint is a parameter of type IPoint


  pNodes is a parameter of type ILongArray

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.


Returns the indices of the nodes that are natural neighbors of the query point. This set represents those the point would connect to if inserted into the triangulation.

If the query point is coincident with an existing node, that nodes neighbors will be returned.

An empty set is returned if the query point falls outside the triangulation.

The passed LongArray must already be instantiated.

The TIN must be Delaunay.
