[Paraview] How to implement a multiview

Thu Jul 23 09:14:07 EDT 2009

Hi Jacques,

That depends on how familiar you are with paraview's servermanager c++ api
and pq (paraview qt) api.  I'm not sure what you had in mind, but you could
create a plugin that adds a panel/toolbar/menu to paraview in which you
provide a button that triggers some c++ code to setup the multiview for your
data.  Most of the c++ code could be written using just servermanager api,
but you'd have to touch some qt code to setup the view layout.

Except for the view layout problem, I think python is easier.  Often what
takes 10-20 lines in servermanager c++ takes just 1 line in python using the
paraview.simple module.
