Oops my bad. You need to add the following to the start of the script:
from paraview.vtk.vtkIOPLY import vtkPLYReader
Thanks

Utkarsh,
Thank you very much for your help! I tried as you said, but still the error.
Did i lack of some settings?
Traceback (most recent call last):
File string, line 19, in module
File string, line 6, in RequestData
NameError: global name 'vtkPLYReader' is not defined
Thanks,

Dxy,
ParaView has certain overhead when a new source/filter is created. It
will need some more profiling, but creating 500+ readers would indeed
push things closer to that limit. ParaView/VTK typically uses
composite datasets/multiblock datasets for handling multiple parts of
the same dataset. Here's a Script for the Python programmable filter
that can open all the PLY files as a single multblock dataset.
# 0. Create the Programmable Source from the Sources menu.
==
# 1. Set the Output DataSet Type to vtkMultiBlockDataSet.

# 2. Set as the Script

output = self.GetOutput()
cc = 0
for i in range(1, 538):
filename = /tmp/data/%03d.ply % i
reader = vtkPLYReader()
reader.SetFileName(filename)
reader.Update()
output.SetBlock(cc, reader.GetOutputDataObject(0))
del reader
cc = cc + 1

Not sure what exactly are you seeing. If you have a sample dataset to
share, that'll make it easier.
Thanks

Thanks for your reply. I tried as you said, it doesn't work. I use a
computer of 16G of memory, it can render out. Then I use 538 ply files,
they
are 11.9MB altogether, but when renderd, it will use 6G memory, either
the
display lists turned on or off. Why it is this?
Thanks for your help.

Try turning of display lists. In ParaView4.1 it was setting named
Immediate mode rendering under the Settings dialog. You'll need to
enable the checkbox.

Dear,
I use the paraview of Version4.1, and the memory of my
computer
is
4G. When I load about 190 ply files at the same time, there will be
errors
about out of memory, but it runs normally when the number of the file
is
less than 190.
The error message as shown below:
ERROR: In

Thanks for your help.
