[Paraview] Parameter Filters

[David E DeMarle]

There isn't an in built mechanism for that.

The python programmable filter runs on the server, so it can not
control other filters along the pipeline (although it can set up
internal filters if you are familiar with programming at the vtk
level).

You best bet may be to use a python macro, which is the same thing
really as python trace or the python shell, ie client side python
scripting. From there you can control properties of filters up and
down the pipeline.

Another tool that might be useful are custom filters. Custome filters
are really canned pipeline segments. Ie construct pipeline a->b->c and
then condense all of that into custom filter Z so that you can reuse
the set whenever you like. You can choose any, all or none of the
properties on filters a,b,c to expose in your new filter Z.
