As far as I know, the extract VOI filter can only be used for rectangular regions? My clipping plane will be positioned in ways that the output will not be rectangular. I've looked in the vtkShepardMethod to sample the output of the vtkClipPolyDate onto a structured grid, I think that this will be the easiest way to achieve my goal?<div>

Have you tried the extract VOI filter?<br>
