Hi all,
I am using Linux and Paraview 3.4 or 3.5. I have one question when I use a
filter on Paraview 3.5 I have a error.
I laught python script with pvpython (or ipython) and paraview 3.4 my script is
running but with paraview 3.5 I have been a Attribut Error with
:reprShrink.ColorArrayName = "Normals"
I don't know why it don't understand a attribut "Normals" on paraview 3.5
There my script belong, if someone can help me to understand where is my bug.
I am new to paraview, but I think it's a bug in Paraview 3.5. What do you think?
Thanks in advance for your kind help.
Regards,
Jona
