Re: [Paraview] Optimus and Windows 10

[Jonathan Borduas]

Was the laptop running with the intel gpu ? If so, it might be related to an 
Intel driver bug that was reported on the QT and Intel websites.

Hi,

In our paraview course two weeks ago we had a student that had trouble
running Paraview 5.4.1 (official windows 64-bit binaries) under windows
10. The symptoms were that the main menu bar was invisible and that the
mouse cursor did not match up with the position of the click event,
making it very hard to do anything. It seemed the menu bar somehow had
shifted under the window title bar, causing the misalignment.

As this laptop was an optimus system we figured it might have something
to do with that. After some fiddling we found that right-clicking on
paraview.exe and picking Run with graphics processor -> High-performance
NVIDIA processor solved the problem.

Is this a known issue?

Regards,
Paul

Jonathan,

As far as I know, no such a setting is not available in ParaView
currently. It's not on our todo list. Feel free to report an issue at
`https://gitlab.kitware.com/paraview/paraview/issues` so that it can
be tackled in the future.

[Paraview] Rendering/Screenshot with "deep color" (REPOST)

[Jonathan Borduas]

Dear Paraviewers,

As seen in the attached image, we can see the transitions between the different 
grays that occur with a 24bits-per-pixel screenshot export of ParaView.
While most image editing software and printer support 32bits-per-pixel such as 
Ms Paint and Photoshop.

Most GPU manufacturers call that "deep color". Some display already have 
30bpp/10bpc.

Is there a setting available to configure the image bit depth (Bit Per Pixel, 
Bit Per Channel) in ParaView ?
If no, is there any short time plans to integrate the control over the bit 
depth ?

Best regards,

Jonathan Borduas

We would like to block the updating of the pipeline upon an error in the 
programmable filter (just like a C++ filter).


Raising an exception in the Python script should a interupt your script, 
however from the code I see that that wouln't exactly do what `return 0` in 
RequestData for C++ filter would. Please feel to report a bug on the issue 
tracker. Should be fairly easy to address in  a future release of ParaView.

[Paraview] Error handling in a programmable filter.

[Jonathan Borduas]

Hi Everybody,

Is there a equivalent of "Return 1" in the python programmable filter ?

We would like to block the updating of the pipeline upon an error in the

[Paraview] Filter guidelines and Frequent pitfalls

[Jonathan Borduas]

Hi to all paraviewers

My team is creating custom filters inside paraview (c++ and python). We 
recently discovered that it's really not a good idea to use paraview.simple 
inside a filter (a developper was updating the panel of the filter with 
paraview.simple.setproperties, creating weird behaviors).

I saw some in the "plugins howto" page, but I guess it isn't complete.

A more exhaustive list of pitfalls could help a lot of people out there. I was 
wondering if somebody has a guideline on the frequent pitfalls, or a kind of 
checklist in a Definition of Done.

Best regards

Jonathan Borduas

Re: [Paraview] Pipeline not respecting the arrow of time after changing the inputs of a filter

[Jonathan Borduas]

Hi Utkarsh,

I was wondering if there is a way to contribute to ParaView in terms of UI 
design and features propositions. I would really like to see ParaView evolve 
not just in term of performance/capabilities, but also in usability.

I understand the requirements are often aligned with performance and bug fixes, 
but maybe to see an actual UI design proposition would convince your customers 
and contributors to go forward with a redesign.

I could definitely help in making that ParaView UI 2.0 proposition, and I am 
sure other users would too.

Best regards,

Jonathan Borduas

Totally agreed. The pipeline browser hasn't been updated since early ParaView 
3.0 days, I'd guess a 2009. It surely can be made better. In the end, it boils 
down to the need and time availability. Since it works well for 80/90% of the 
cases, we (and our customers and contributors) often end up prioritizing other 
features and bug fixes. We do offer various consulting 
options<https://www.kitware.com/what-we-offer/#consulting>, if you're keen on 
getting it updated .

Jonathan,

The arrow is not intended to have a "top/down" direction, just a "back-to-root" 
direction. It can be interpreted as "ProgrammableFilter1" can be found 
somewhere on the main trunk.

[Paraview] Pipeline not respecting the arrow of time after changing the inputs of a filter

[Jonathan Borduas]

Dear ParaViewers,


I came across some weird behaviour in ParaView: We have a custom 
BooleanOperation filter that have two outputs (custom ParaView build).
If both outputs are the inputs of an Append Geometry and we update the inputs 
of the BooleanOperation Filter, the Append Geometry will be moved before the 
BooleanOperation Filter.


I always though that if there was any dependencies in a pipeline, the 
representation would respect the "arrow of time" that goes from top to bottom.
Please look at the picture here attached (same behaviour with a 
ProgrammableFilter instead of a Append Geometry).


Is my comprehension at fault here or is it a bug ?


Thank you,

Jonathan Borduas

Re: [Paraview] Programmable filter - script for mean of two input PointSources

[Jonathan Borduas]

Hi, 

What is the best way to proceed if someone wants to use the new coordinate 
(mean of the two dots) in another filter using a Link. For instance, I would 
like to use the coordinate as the Origin of a Clip filter. 

Thank you,

PointSources

Here's a simple trick:

1. Select both point sources in pipeline browser and then create the "Python 
Calculator".
2. Use the expression "(inputs[0].Points + inputs[1].Points)/2.0", and hit 
"Apply"
3. Next, create the "Calculator" filter connect to the "Python Calculator" with 
expression "result" and also check the "Coordinate Results" checkbox. Hit 
"Apply".

That should do it.

Example state file attached.
