[Paraview] [EXTERNAL] Re: Paraview 5.4.1 error message & freeze

Sonya,
If nothing else works, use ParaView 4.4.0.  That release is a workhorse, and was the version before we updated OpenGL requirements.

Subject: [EXTERNAL] Re: [Paraview] Paraview 5.4.1 error message & freeze

Hello Cory & Paraview team,

I am just giving below a SUMMARY on the errors I encountered while working with ParaView.

Version 4.0.1 installed on my old (2013) 64-bit Toshiba laptop under Windows 7: works fine, shows images for model.vtk & glyph for data.vtk; does not freeze.

Version 5.4.1 just DOES NOT install on my old (2013) Toshiba laptop.

Version 4.0.1 installed on a new (2016) Dell laptop under Windows 7: shows images for model.vtk & glyph for data.vtk, but freezes while attempting to do full screen or just to drug the screen edge in order to increase screen with the following diagnostics:
--------------------
Output messages
QWidget:: repaint: Recursive repaint detected.
---------------------

Version 5.4.1 installed on a 2016 Dell laptop under Windows 7: shows images for model.vtk, BUT glyph for data.vtk STAYS EMPTY, and the application ALSO freezes while attempting to do full screen or just to drug the screen edge in order to increase screen, with no diagnostics.

- - - - - - -
So, for now I have to continue working with version 4.0.1, and it is fine, so far, for the learning purpose. To prevent freezing, I simply avoid to increase screen / full screen.

The  version 4.0.1 was my random choice, just the first version I saw available for 64-bit system.
Would you recommend for me to try any newer version?

Many thanks for your help,

Sonya Davydycheva

Cory,

The Glyph works just fine with my data.vtk and is very useful tool! It was a good advice.

As to not-responding and freezing of ParaView: let me accumulate statistics and then I will let you know.

I appreciate your help,

Sonya Davydycheva

Thank you Cory,

For your prompt response. Good to know that the message is harmless.

My Paraview 5.4.1 just stops responding sometimes.

If it stops responding consistently after a specific event or sequence of events, please let us know. It shouldn't do that :-)

But, well, I installed on another (older) laptop an older version, 4.0.1 (5.4.1 did not work there), and it does not freeze. So far, I think it is ok for my learning purpose.

Very good.

Both versions (on both computers) allow me to visualize my sample model.vtk file: in RenderView I can do Threshold, Slice and Clip and see some 3D pictures. But something is wrong with my other sample data.vtk file (or, with my approach?). It contains data points (3 coordinates) and the resistivity values assigned to them. When I open it, I can see only the resistivity colorbar, and I can add axes, but the image stays empty.
Threshold does not work at all (and even the colorbar disappears when I apply it).
Slice somewhat works, but it stays gray/empty and does not change as I move it along the box.
And when I am in "Slice" mode, pressing "Apply" removes the colorbar as well, and does not show anything meaningful.

Any idea how can I activate Threshold or Slice for my resistivity data.vtk?

I am beginner and suspect I just miss something simple...
Reading ParaViewGettingStarted-5.4.0.pdf and ParaViewTutorial54.pdf, does not help, so far.

I suspect that you do not have any cells in your 3-point data.vtk file. Without cells, there is nothing for ParaView to visualize. This is a common stumbling block for people trying to visualize point data.I suggest after loading your data applying a Glyph filter. It should show you three spheres colored according to your resistivity array. Now you should be able to apply the Threshold and Slice filters as you would expect.

Thanks,
Cory

Many thanks in advance,

Best regards,

The message is a warning from the Qt side. Aside from being annoying,
it should be harmless. Sorry, but we haven't figured out why this
appears on some systems and not others.

Does it stop responding or does it crash? It's probably not related to
the warning message above.
