[Paraview] question about programmable filter

[Cory Quammen]

Sergey,

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.

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.

Best,
Cory
