Hi Berk, Thank you for your reply. One of the priorities of our in-situ visualization work is speed, so moving data to main memory may not be a preferred approach. We just need several basic visualization functions(e.g. slice and contour ) and analysis functions(e.g. sub-sampling ). Is it possible that we write our own filters running on GPU and integrate them into the current VTK pipeline? Since the sources, readers,writers and filters are configured via XML file, if we set up the appropriate filter XML configuration file, will it work for us ?
