[Visual Basic .NET]
Public Function LocateMultiple ( _
    ByVal pRay As IRay _
) As IMultipoint

[C#]
public IMultipoint LocateMultiple (
    IRay pRay
);

[C++]
HRESULT LocateMultiple(
  IRay* pRay,
  IMultipoint** ppLocations
);

[C++]

Parameters
pRay [in]

  pRay is a parameter of type IRay
ppLocations [out, retval]

  ppLocations is a parameter of type IMultipoint

Product Availability

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

Description

Returns the intersection points between a 3D ray and the surface.

The returned multipoint will contain 0..n points depending on the number of intersections between the ray and the surface.

 

Notes:

Consider using ITinSurface3.QueryLocate or ITinSurface3.QueryLocateWithinDistance when inside a loop, for the sake of efficiency, since those methods allow you to reuse output point and multipoint objects whereas this method always creates new ones.
