Carlos, I suspect the warp by vector filter is removing the normals because in general warping a surface invalidates the normals. Perhaps a feature request could be to add an option to warp by vector to preserve the normals.
There is a filter to generate normals on a polygonal surface. It works by averaging the normals of incident polygons, but I don't think it is weighted by area. -Ken From: ParaView <[email protected]<mailto:[email protected]>> on behalf of Carlos Baumann <[email protected]<mailto:[email protected]>> Date: Monday, April 25, 2016 at 11:16 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [EXTERNAL] [Paraview] Paraview not using normals data when rendering WarpByVector Hello Paraview ! The attached .vtk file has quad elements defining a tube, for each point or node it has defined a scalar Pressure, and two vectors, Displacement and Normals. When I render “Displacement Magnitude” on the surface, the normal are used, this is perfect and this is what I want, see attached snapshot, However when I use WarpByVector to deform the geometry, and plotting “Displacement Magnitude” on the surface, the normals are not used, each element uses its own normal, and I see the facets. How can I change this so that the normals that I have defined in the .vtk file are used ? Ideally I would want Paraview to use the normal at any point/node by averaging the normal of all the elements attached, weighted by the area, can this be done automatically with GUI settings ? Thank you in advance for your help. Regards, Carlos
