Re: [Paraview] [EXTERNAL] Re: Extracting data on the surface of a block?

Hi Louise,
To find Chart View, look for the words RenderView, to the left of the view 
splitting icons.  Right click just left of there, in the white open header 
area.  Select Convert To...

Re: [Paraview] Extracting data on the surface of a block?

[Steytler, Louis Louw]

Hi Utkarsh,

My data file is rather large, but here is a link to the data:

https://uofi.box.com/s/u4hpipt8kbo0u3oxhz92xeya75kzf6kd

Please let me know if this is too large and I can try to send a smaller version.

I have been using "save data". It seems I have data sets under the "Composite 
Data Set Index" list in the PlotOnIntersection pipeline.

How is "Chart View" selected again? I didn't find it in the "View" drop down 
menu at the top, but I was able to open a new layout and select 
"SpreadSheetView".

Thanks again,

By "Export View", I meant "Export Scene" under the "File" menu.

Re: [Paraview] Segmentation fault when loading representation plugin on Linux paraview

[Utkarsh Ayachit]

Even with fb13726dbfdcb5479c393720abaf8234edd42609, it fails to build. I'll
wait for you to update your code to build with latest ParaView before
testing it. A quick look at the "AddToView" method and I don't see anything
wrong with it, so it will need some debugging.

Re: [Paraview] Segmentation fault when loading representation plugin on Linux paraview

​I'd like to share, the code works well on Paraview version
fb13726dbfdcb5479c393720abaf8234edd42609
(version on Dec 1 2017), The latest has changed some source code, and I'm
working on fix it.
Thanks.

Are you referring to the circular (polar axes) in the image? It says
90.0 deg, 45.0 deg., etc.

It sounds like it. I believe that the user would have to use the extract

Re: [Paraview] [EXTERNAL] Re: Material Interface Filter

[Scott, W Alan]

Andy,
Wouldn't the upcoming volume filter calculate the volume of fragments coming 
from the Connectivity filter?

Re: [Paraview] Segmentation fault when loading representation plugin on Linux paraview

[Utkarsh Ayachit]

Maybe if you share the code for vtkLIC3DRepresentation I may be able
to offer suggestions. You could also try getting a access to some
other linux machine on which you should be able to reproduce the
issue.

Re: [Paraview] custom view plugin - minimal example needed

[Kolja Petersen]

Thanks, Mathieu, unfortunately the RenderView or the other hardcoded views
won't work for us.
As I described, I need to implement a custom view with a bunch of input
fields and buttons to represent data statistics.

The corresponding Qt views of the 4 mentioned View classes are created in
pqStandardServerManagerModelInterface::CreatePQView using hardcoded tests
such as:
 if (xmlname == pqSpreadSheetView::spreadsheetViewType())
  {
return new pqSpreadSheetView(group, name, proxy, server, parent);
  }
Is it feasible to create another, generic vtkPVView-derived class besides
vtkPVRenderView...vtkSpreadSheetView, which will allow to define the view
elements using the plugin mechanism?

We can add menus, buttons and toolbars through plugins, why not customize a
generic view? Is there a reason that forbids such customization, or is it
just one of those topics that hasn't received sufficient interest or
funding, but could be implemented in principle?
Thanks
Kolja

 I don't know how I can further shorten my question. The answer is quite
 important to decide whether we can continue our ParaView developments.

Re: [Paraview] Segmentation fault when loading representation plugin on Linux paraview

I run this paraview on TACC Maverick, which I have no access to debug
build. But I run the same plugin on my Windows Paraview build and there is
no such error. How could I fix it?

Re: [Paraview] Segmentation fault when loading representation plugin on Linux paraview

[Utkarsh Ayachit]

My guess would be that you're accessing a nullptr in
`vtkLIC3DRepresentation::AddToView`. I'd recommend doing a debug build
of ParaView, and then attaching a debugger to confirm and fix.

Re: [Paraview] OSPRay ignores transparency

[David E DeMarle]

It is a known bug in VTK's interface to OSPRay such that opacity is ignored
in some cases dependent on some of the other color controls.

[Paraview] OSPRay ignores transparency

[Nenad Vujicic]

Hello everyone,

I tried both ParaView v5.4 and current v5.5 binaries, Windows x64, but,
when I set a surface object opacity to e.g. 0.5, then enable OSPRay,
surfaces goes back to fully opaque. Is transparency currently ignored?

Thanks,
Nenad.

Re: [Paraview] Catalyst dlopen issues with OpenGL2 support for off-screen Mesa

[Andy Bauer]

Hi Yvan,

Thanks for the update.

I haven't seen anything like this yet but if I'm able to reproduce it I'll
see if I can track down the issue.

Best,
Andy

By "Export View", I meant "Export Scene" under the "File" menu.

Louis,

PlotOnIntersectionCurves essentially slices the dataset using a
implicit plane. The points you get are indeed the insection points
between your polydata and the plane and hence there's no control over
how many points there can be, besides what's determined by your mesh.

If you can share the sample data (feel free to do it off the list,if
you'd like), I can see what other options may work.

>Also,  upon saving, three files were produced file0.csv, file1.csv, file2.csv,

Are you using "save data"? I'd suggest selecting the "Chart View" and
then using "Export View" option to export the curves. That will give
you a since CSV for the fields you've selected.

Re: [Paraview] [EXTERNAL] Re: Material Interface Filter

[Cory Quammen]

As a happy coincidence, Will Schroeder just posted a merge request for
a VTK filter that computes the volumes of connected regions in a poly
data and stores the volumes in field data:
https://gitlab.kitware.com/vtk/vtk/merge_requests/3825. We could
expose this in ParaView once it lands in VTK.

Re: [Paraview] custom view plugin - minimal example needed

[Mathieu Westphal]

Hello

Here is a minimal example for creating a new type of view within a plugin.
You actually cannot inherit directly from vtkPVView, you must inherit for a
base view, which can be :
 - vtkPVRenderView
 - vtkPVContextView
 - vtkPythonView
 - vtkSpreadSheetView
(
https://www.paraview.org/ParaView/Doc/Nightly/www/cxx-doc/classvtkPVView.html
)

This choice is also visible in the associated xml files where you precise
which kind of proxy you want to create.

In the attached example, I demonstrated how to add a clone of the Render
View, called Render View 2.

Hope it helps,

Best,


Mathieu Westphal

 I have stripped down Plugin/MantaView until all compilation problems

 The code, consisting of only two minimal classes, is attached and can
 be built using:
 unzip snippet-viewplugin.zip && mkdir build && cd build && cmake && make
 (tested with ParaView 5.4.1)

 This brings me back to my initial question. I'd like to show a custom
 view, made of a number of Qt widgets (buttons and text) to show important
 statistics.
 In SnippetView.xml, the view is declared as:
 >>> base_proxyname="RenderView" ...

 How can I replace 'base_proxyname="RenderView"' by some generic view,
 to be filled with widgets? "View" or "ViewBase" are not recognized as base
 proxies.
 Thank you
