[Paraview] Construct Point Set in Python

[Robert Maynard]

Currently I am unable to figure out how to create a set of points in
paraview with the python shell or programmable filter. I have constructed a
script
that can read a database and output a single point source for each point
(see below). Is there something I am missing to instead construct a point
set, or will I have to create a point set source object first?

#!/usr/bin/env python
import time
import sys
import paraview
from pysqlite2 import dbapi2 as sqlite

COLS_TO_GET = 100

# 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()
iter = pxm.group_iter("view_modules");
activeView = None
for proxy in iter:
  if proxy.IsA("vtkSMRenderModuleProxy"):
    activeView = proxy
    break
if activeView:
  db = sqlite.connect('/home/rmaynard/ProjParaview/rmaynard/Python/mine.db')

  c = db.cursor()

  #start time tracking
  startTime = time.time()

  c.execute('select * from data where lbExpl > 0')
  cols = c.fetchmany(COLS_TO_GET)
  for row in cols:
    grab the row x, y, z
    (x,y,z) = row[:3]
    point = paraview.CreateProxy("sources","PointSource","sources",
"point.%d.%d.%d"%(x,y,z))
    point.SetCenter(x,y,z)
    point.UpdateVTKObjects();
    disp = paraview.CreateDisplay(point, activeView);

  activeView.StillRender();
  #end time tracking
  endTime = time.time()
  print endTime-startTime
  c.close()
  db.close()
