Hi all,
I have just imported a 3D parametric surface in Paraview (from a .VTU file
generated by a Python script), and I'm wondering how to display the cellNormals
as actual vectors. Since a cellNormal has an X, Y and Z component, it should be
possible to use these three scalar values to create
Does the file actually contain normals? I am guessing not. In that case, do:
Extract Surface
Generate Surface Normals
Glyph
If you had a vtp file (polydata) instead of vtu (unstructured grid), you
wouldn't need to Extract Surface.

ParaView does a weird thing, in the "Color By" drop down menu, it show an
array named "cellNormals" but this array doesn't actually exist on the data
object, and it doesn't appear in the information tab. So, as Berk said,
you should apply the Generate Surface Normals filter, and make sure you

Hi Pat, Berk,
Thanks for your replies. Displaying the cellNormals works fine now, but I
still can't select the normals computed in my Python script from the
dropdown menus in the Glyph filter.
I uploaded the relevant .VTU file to my web space, you can find it at

Try the Cell Centers filter. Out.vtu --> Cell Centers --> Glyph.
