You can use the Resample With Dataset filter to apply the field values of the unstructured grid to the surface of the poly data. It is roughly equivalent to intersecting the unstructured grid with the surface.

This gives an image of resistivity (the colour value) in 3 dimensions. I also have another image giving the maximum depth to which I can trust the previous data. This is a polydata dataset of point data, where the points are simply the depths. Is it possible to clip or threshold my original image (the unstructured grid) according to the depths given in the polydata? I.e cut away any data in the original image that is below xx depth, where xx is given in the polydata surface?
