Hi Ufuk, The threshold filter operates on scalar/single component arrays only. Also, underneath the covers it operates on cell data exclusively so if you request thresholding on point data it will do a point data to cell data operation as well.
I'm not aware of any filters in PV that would allow you to track a thresholded quantity. Unfortunately I can't think of any moderately easy way to do this in PV either.
