<div>Have you checked out vtkBoxWidget? It takes care of a lot of cropping work for you automatically. There is an example file that shows how to enable cropping of a volume with it (check the online class documentation for the link). I've only used vtkImageData -> vtkVolume as its input, but it will probably work with vtkStructuredPoints -> vtkVolume too,
