Hello,<br>
<br>
thank you very much !<br>
<br>
Do you know if is possible to write directly a reader in python ? <br>
<br>
Or is it only possible in C++ ?<br>

from a vtkStructuredGrid object, I use a vtkStructuredGridWriter to create a
vtk file, and I have the following problem :
when I launch the script in Paraview, the format of floating points is not
good (I obtain for example 33,1632 instead of 33.1632). So, the file created
is not readable by Paraview. If I launch the script directly in a terminal,
it works fine. Perhaps because the version of vtk module is not the same ?
If I use the binary format I have not this problem.

<pre wrap="">This seems to be related to the way the LOCALE is set on your system. It is
probably set to French in one case and English in the other. Does anybody know
if we can force LOCALE to English in the ParaView application or the reader?

any ideas ? I try to use LegacyVTKFileReader instead, but I have also some
problems.
I use a re-compile version of Paraview 3.8, under Linux (Fedora 10 - 64
bits)
thanks for your help.
