Re: [Paraview] BUG REPORT: Axes grid option grayed out, version 5.4.1 64bit, on Ubuntu 16.04

[Cory Quammen]

Hmm, that's strange. Can you give step-by-step directions on how to make
the buttons grayed out, preferably with a simple starting source such as
the Sphere source or Wavelet source?

Thanks,
Cory

[Paraview] BUG REPORT: Axes grid option grayed out, version 5.4.1 64bit, on Ubuntu 16.04

[Jianbo Long]

Hello,

I am trying to add axes information to a clipped 3-D mesh, which was
generated by clipping, slicing, and clipping of a 3-D mesh from a .VTK
file. However, in the latest Paraview version 5.4.1,  the  'Axes grid'
option sometimes doesn't work (grayed out, please see attached picture). I
remember I could use this button a few days ago with the same version.
Even after restarting Paraview,  there's no luck.  This was not a problem
in previous versions 4.4 and 4.0.  I would like to use v5.4 because this
version has more controls over axis properties like fonts.

Could you give any ideas about this issue ?

Thank you very much,

Jianbo Long

Re: [Paraview] Filter suddenly stopped working "did not create output for port 0"

[Chris Marsh]

OK I have it working on my end.
I had previously configured paraview with ccmake and set build type to
Release and enabled Python.

Any idea how that may impact this?

Re: [Paraview] Filter suddenly stopped working "did not create output for port 0"

[Chris Marsh]

Hi,

Thanks for trying this. Good call on the removal of the extra CMake stuff.
It was there because I started this filter before I knew about things like
setting ParaView_DIR and forgot to update this!

Interesting that works for you. I just rebuilt with the change to use
ParaView_DIR
(on the off chance it changed something...) but still broken on my end. :(

So, this isn't an issue with the filters code, but rather something with
how either I compiled Paraview or ... something?

Are you using the github version of paraview?

Cheers
Chris

Re: [Paraview] animation: files, pgmable source

[Heiland, Randy]

Utkarsh,

Thanks very much for that!  Yes, after some fiddling, I got it to work, i.e., I 
can save .png files for an animation! So now that I’m using the Programmable 
Source(RequestInfo) script to accomplish the animation, how do I, during a PV 
session, *easily* switch back to render a single file?

For example, I can do:
frames = range(0,801,100)   #  render every 100th frame, including 800
setOutputTimesteps (self, frames)

or, I can explicitly list specific frames:
frames = [100,101]

so, I thought this would do a single file, but it doesn’t (my previous frames 
are still there):
frames = [600,]

-Randy

[Paraview] from matlab to paraview

[Doina Gumeniuc (224252 MAHS)]

Hi all!


I have created a vtk file in matlab and I would like to export it to paraview. 
I need a script/function which would load this vtk file from matlab to paraview.

I would really appreciate if any of you could share some hints or some links 
where such a process is explained.


Thank you!
