[vtkusers] VtkInteractorStyleRubberBandPick

[Darshan Pai]

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

Regards
Darshan
