Hi,
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 IN MY VTK FILE (and NOT the Normals Glyphs calculated by the software) (I have these normals calculations in another code and I do not want to change that). I am importing a mesh in Paraview from a VTK file. The VTK file contains the following elements: # vtk DataFile Version 2.0 hydrodynamic vtk mesh for paraview vizu ASCII DATASET POLYDATA POINTS 458 float x0 y0 z0 (points coordinates) ... ... ... ....... POLYGONS 465 2325 4 n1 n2 n3 n4 (points IDs) 4 ... ... ... ... ...... CELL_DATA 465 NORMALS cell_normals float ... ... ... (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
