[vtkusers] combine vtk

[Meehan, Bernard]

This is a python script, and I haven't actually run this
but it should work something like the following:

import glob, vtk

# get a list of VTK polydata files in your current directory
files = glob.glob("*vtp")

# create an append filter to hold your data
append = vtk.vtkAppendPolyData()

# loop over your files
for f in files:
  rdr = vtk.vtkPolyDataReader()
  rdr.SetFileName(f)
  append.AddInputData(rdr.GetData())

# make sure your data is updated
append.Update()

# write out your appended data
writer = vtk.vtkPolyDataWriter()
writer.SetFileName("big_glob_of_polydata.vtp")
writer.SetInputConnection(append.GetOutputPort())
writer.Write()

Thanks for the link. Unfortunately I'm not a programmer by any means, so I'm
still a bit lost. I have VTK and vtkAppendFilter built on my machine. Could
you give me an example on how to read in the data using vtkPolyDataReader? I
have a general understanding on what tools' functions, but not so much on
how to execute them. Thank you
