When opening a file, paraview forces you to click Apply before you can do anything else (such as creating an Extract Subset filter). Thus, the data reader uses UPDATE_EXTENT=WHOLE_EXTENT and you may run out of memory before being able to subset the grid.
if instead, you instantiate your reader, do not execute it, do not create a representation for it, then create an Extract Subset with the VOI you desire, and then execute the whole thing, you will end-up passing the VOI extents upstream directly to the reader, and your reader will only execute once with the correct extents. Use the python shell and the followin example: reader = XMLImageDataReader( FileName= '/path/to/data/foo.vti'] ) reader.PointArrayStatus = ['data1'] ExtractSubset1 = ExtractSubset() ExtractSubset1.VOI = [2000, 2255, 2000, 2255, 2000, 2255] DataRepresentation2 = Show(ExtractSubset1) Render() Jean-- Swiss National Supercomputing Center _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
