Dear Paraview, I am new to this list, so I would like to immediately apologise if my style does not meet your standard.
I am learning to use Paraview, and I have problems using the threshold filter. I have attached 2 .vtk files based on documentation examples to explain my point I use filters->common->threshold, then specify Scalars->cell_scalars and choose range [1,3]. * For the "polydata.vtk" I observe some of the rectangles disappear as expected. If I manipulate the range, I can get any one rectangle disappear. * For the "unstructured.vtk" I see all but one triangle disappear, which is unexpected. If I manipulate the range, either the tetrahedron disappears altogether, or only one triangle is visible. Could you please tell me what am I doing wrong? ---------------------------------------------------------------------- Paraview Version 4.1.0 64-bit QT Version 4.8.2 Linux debian 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u1 x86_64 GNU/Linux ---------------------------------------------------------------------- Thank you, Aleksejs Fomins
