[Paraview] python scripting inside Paraview

[Utkarsh Ayachit]

Hi Robert,

To make a source visible one needs to create what we call a "display" 
for that source. "Display" is a proxy which encapsulates the 
vtkMapper,vtkActor etc. Once must create the display for the source and 
then add it to the render module in which we want to "see" the source.

Here's the script that one can use to do the same:

import paraview
sphere = paraview.CreateProxy("sources","SphereSource","sources")


# Locate the view to which we'll add the "display". All views are
# registered in the group "view_modules" with the proxy manager.
pxm = paraview.pyProxyManager()

# Create a iterator that iterates over all proxies registered in
# a particular group.
iter = pxm.group_iter("view_modules");
activeView = None
for proxy in iter:
   # Locate a 3D render view.
   if proxy.IsA("vtkSMRenderModuleProxy"):
     activeView = proxy
     break
if activeView:
   # create a display for the source in the active view.
   disp = paraview.CreateDisplay(sphere, activeView);
   # Trigger a render.
   activeView.StillRender();
