Contour creates normals from AMR data, whether desired or not.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
ParaView 3.6.2, XP, local server. Open Dave's small cth dataset. Only Material Volume Fraction 2 on. Apply. Cell to Point filter. Contour filter. Contour on Material Volume Fraction 2. Turn OFF compute normals. Apply. You can still color by normals. If you ask to not have normals, they should not be generated (and thus taking up memory).
Since this is the main way we visualize LARGE data, this should be fixed for 3.8.
