    ByVal pPoint As IPoint, _
    ByVal pTriangles As ILongArray _
public void QueryTriangleNeighborhoodIndices (
    IPoint pPoint,
    ILongArray pTriangles
HRESULT QueryTriangleNeighborhoodIndices(
  IPoint* pPoint,
  ILongArray* pTriangles


pPoint [in]

  pPoint is a parameter of type IPoint


  pTriangles is a parameter of type ILongArray

Product Availability

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


Returns the indices of all triangles that would be effected if the query point were inserted in the triangulation. These are the triangles whose circumscribed circles contain the query point.

No special attention is paid to the presence of breaklines or whether the query point falls inside the interpolation zone. Triangles connected to super nodes may be included in the returned set.

An empty set will be returned if the query point resides entirely outside the triangulation (including the super node extent).

The passed object that implements ILongArray must have already been instantiated.
