Leo, Here is the *.tex file. Sorry for the trouble with the *.pdf file. For whatever reason, my "tool chain" here (WinXP-64; :-) = emacs-21.2 = *.tex = latex = *.dvi = dvips = *.ps = GSview+ImageMagick-6.3.3-Q16 = *.pdf = Adobe Reader-10.1.3) works

Hi, This is not really a bug, but just what the linear precision integration does. As you can see in vtkIntegrateAttributes.cxx:215, the quad cell is basically cut into two triangles along a diagonal, integration is done for each triangle and the results are added up. So, depending where

Hi all, Now I found a bug of the filter. My ParaView's version is 3.14.1. I define node names as below: c--d | | a--b Case 1: a=1.0, b=0.0, c=0.0, d=0.0 Integration Value = 0.3 Case 2: a=0.0, b=1.0, c=0.0, d=0.0 Integration Value = 0.1 Case 3: a=0.0, b=0.0, c=1.0, d=0.0
