Hmm, I guess you could use the Delauney 2D or 3D to create an area or volume but it might be tough using those since they grids they create may not be a good representation of your data geometry. I can't think of anything better than a programmable filter to get the desired translation amounts and then do the translation in the filter as well (maybe using numpy or efficiency). You can save it as a custom filter so that you don't have to enter the python code every time you want to do the centering.
