<div dir="ltr">Sergey,<div><br></div><div>While Aron is correct about learning how to do Python scripting of the ParaView application via tracing, doing so won't necessarily help you write a Programmable Filter, which operates entirely without knowing that it is executing inside of ParaView. Tracing doesn't record the internal VTK operations that you would need to write in a programmable filter. Instead, it records the ParaView-level execution, which is higher level.</div><div><br></div><div>Someone may help you with the filter if you provide a starting point showing what you tried and describing how it doesn't work. It is much less likely that someone will just write the filter for you.</div><div><br></div><div>Best,</div><div>Cory</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Aug 5, 2017 at 1:19 PM, Aron Helser <span dir="ltr"><<a href="mailto:aron.helser@kitware.com" target="_blank">aron.helser@kitware.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Sergey,<div>A good way to start writing something in Python is to use the 'start trace' in the Tools menu in ParaView.
