OK, this … sort of … worked. I was able to use the Kitware download (Yay!). I called pvbatch (surprisingly, it was built by Kitware for Linux), and then used flags --mesa-llvm and --use-offscreen-rendering. I believe --use-offscreen-rendering will be replaced in the future by --force-offscreen-rendering in PV 5.5.0.
Thanks Cory, and everyone else that chimed in.

The help for --force-offscreen-rendering says: "If supported by the build and platform, create headless (offscreen) render windows for rendering results." I believe this should work on linux systems, but you should try it out on the system on which you want to force offscreen rendering just to be sure before using it to produce classified images. pvbatch running the same script will indeed not pop up a render window even without the --force-offscreen-rendering option. Let us know how it goes, Cory On Mon, Nov 13, 2017 at 5:04 PM, Scott, W Alan <wasc...@sandia.gov<mailto:wasc...@sandia.gov>> wrote: Ben, I believe this is a change from the past. Here is what I desire – how do I get it? I want to run pv(pythonScript). I want it to produce output. I want it to run off screen, not showing on the console display or current display. This is especially important on classified systems. MPI is not available. Not too long ago, my understanding was this was pvbatch. pvpython used either the console display or current display as it’s rendering space. This does not catch my needs.

Where is this documented? pvpython is the non-MPI version of pvbatch. The superbuild docs could probably be improved here. Currently, the mention is: ParaView supports multiple rendering engines including `egl`, `mesa`, `osmesa`, and `qt5`. All of these are incompatible with each other. If none of these are chosen, a UI-less ParaView will be built (basically just `pvpython`). On Windows and macOS, only the `qt5` rendering engine is available. --Ben _______________________________________________ Powered by www.kitware.com<http://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 Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview -- Cory Quammen Staff R&D Engineer Kitware, Inc.
