Dear community ,
I am trying to visualize array of atoms with their displacement vectors in
Paraview. The structure is complicated and cannot be represented by
StructuredGrid. The goal is to have slices with surface vectors (displacement)
and atoms. I have tried two ways:
1. Generate a
Dear Oksana,
You do need to generate a volumetric mesh first and then slice it to
generate a polygonal mesh. The volumetric mesh needs to interpolate your
values in space somehow. This is what Delaunay would give you - it will
generate a mesh where each atom is a node of a tetrahedra and the value
Let's try to refine this. How would you pick which atoms to project to the
plane? Keep the atoms that are under a certain distance to the plane? Also,
once you project the points on the plane, are you looking to interpolate
the values on the plane continuously or simply show the vectors as glyphs?
Sorry Oksana. I have been swamped. I hope to get back to you soon. The
solution will be to use the Python Calculator or Programmable Filter to do
the projection of the points on the plane and threshold based on the
distance. There are instructions on how to use these on the Users' Guide. I
also wro
Dear Berk,
Thank you for the reply. I was trying to use the Python Calculator. I created
a plane source, but I do not know how to put it into projection calculation.
The idea was to use one normal vector to find dislacement vectors projections
in a plane. How to create a threshold I have no i
Berk, thank you for the ideas! I have made the projections using Programmable
Filter. It is really very powerful tool.
Oksana

You are welcome :-) Sorry I wasn't able to help a bit more. I was
traveling. Maybe you could share your code with the list? I am sure others
would benefit from this.
Best,
