<p>Hi,</p>
<p><br>I am a new user of Paraview. I am facing a problem I cannot solve and I have not found any relevant practice on the internet (guide user, mailing, ...)... I want to visualise my mesh with normals specified <strong>in my VTK file</strong> (and <strong>NOT</strong> the Normals Glyphs calculated by the software) (I have these normals calculations in another code and I do not want to change that). </p>
<p>I am importing a mesh in Paraview from a VTK file. The VTK file contains the following elements:</p>
<p> </p>
<p># vtk DataFile Version 2.0<br>hydrodynamic vtk mesh for paraview vizu<br>ASCII<br>DATASET POLYDATA<br>POINTS 458 float<br>x0 y0 z0 (points coordinates)</p>
<p>... ... ...</p>
<p>.......</p>
<p>POLYGONS 465 2325</p>
<p>4 n1 n2 n3 n4 (points IDs)</p>
<p>4 ... ... ... ...</p>
<p>......</p>
<p>CELL_DATA 465</p>
<p>NORMALS cell_normals float</p>
<p>... ... ... (normals coordinates)</p>
<p> </p>
<p>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. </p>
<p>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. </p>
<p><br>Thanks a lot,</p>
<p>Best regards.</p>
