View source for ParaView Tips

This page will have a handful of ParaView tricks that I find handy, and will probably want to make use of in the future.

=Stereoscopic Batch rendering=
I gave a talk on the ins and outs of ParaView stereoscopic batch rendering:
* [https://www.tacc.utexas.edu/documents/10165/1147324/02+Creating+Animations+with+Paraview.pdf/51d89121-5610-4dd0-bbec-eef15df5cd38 SuperComputing 2004 talk on stereo animation batch rendering]
Here's my main example of creating a "pvbatch" to render a stereo pair of images.
