Thanks for the reply . tThe FrustrumSelection works best . Though I have a problem. I need to save this new extracted dataset but I am not able too . If I convert to a Polydata it crashes . If i cast it as a PointSet it works but I cannot visualize it at all . It there some way to save the data . I am trying for sometime and I cannot get anything<br>

I believe you are looking for Frustum Selection. That picks all<br>
cells/points behind the rubber band not just the ones nearest the<br>
camera like HardwareSelector does.<br>
<br>
See Rendering/Testing/Cxx/TestAreaSelections.cxx for an example of both of them.<br>
