Hi all,<br>
<br>
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 a vector, pointing from the corresponding cell.<br>
<br>
I know I can create a vector field with the Glyph function, but I'm not sure how to continue from there. I cannot select any Scalars or Vectors from the two dropdown menus/lists (they are enabled but there is nothing to select).<br>
<br>
Any ideas on how to proceed would be very welcome!<br>
<br>
Best,<br>
Pieter<br>
<br>
PS: I'm using Paraview 3.98.1 on a Linux machine.<br>
