[Paraview-developers] How to add multiple inputs to a plugin (writer)

[houssen]

Hi Cory,

My need is very basic (natural) : I'd like to save (with a plugin 
writer) "what I see in the ParaView 3D viewpoint".
Ideally, I'd would like to save "only shown items" in the pipeline 
browser (not the hidden items - gray eye associated to each pipeline 
item).

How to do this ? (use multiple input port ? get the pipeline and scan 
it piece by piece + write each piece only if it is in "show" mode) Is 
there an existing example of that ?
