Hi Vincent,
I can't find what is happening. If you can, please attach sample data to your mail. I tried displaying normals of Sphere sources, and succeeded with the 3D Glyph filter. It's better for you to try simple datasets.

(normals coordinates) A 'cell_normals' array appears in 'Information'; I am able to color the surface (each cell) of the mesh according to the values of the cell_normals array (Magnitude, X, Y or Z) but nothing more. This gives me information on the normals orientation but I have no visual on the vectors. How is it possible de visualise these normals (displayed as vectors) on Paraview without calculating them with the software? What is the correct pratice ? I need to know if they are well oriented, I also need some visual on the mesh I am studying. Thanks a lot, Best regards. -- Vincent _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
