[Paraview] How to clip an image according to a surface?

[james ramm]

Hi
Thanks, but this simply colours the polydata surface with the values of the
unstructured grid. I want to cut all the data in the unstructured grid that
lies below the polydata, but keep all the cells that lie above, not just
extract the polydata surface
