Re: [Paraview] StreamTracer: Combined ReasonForTermination or select individual polylines?

[Andy Bauer]

In Python you can do something like create a Threshold filter to

# create a new 'Threshold'

threshold1 = Threshold(Input=streamTracer1)

threshold1.Scalars = ['CELLS', 'SeedIds']

threshold1.ThresholdRange = [1.0, 2.0]
threshold1.CellData['ReasonForTermination'].GetRange()

This will give you the range of values in the threshold output for the
ReasonForTermination array. You can query the number of seeds for the
high resolution line source with .SeedType.Resolution

 My question is: Can a user create more cases of ReasonForTermination so
 that we can tell examples like above? Or, how can I select individual
 streamlines by its SeedIds (I tried IdsSelection, but that appears to work
 for cell/point data only, not for polydata?)

 My current solution is to use threshold filter to select lines in the
 different regions and apply different solid colors. But it would be nice if
 I can handle a few different cases more directly, even if that involves
 some coding in C++ or Python.

 Thanks.

Re: [Paraview] Remote rendering to multiple displays

[Léo Pessanha]

I believe I was not clear.

The 6 viewports I want to achieve cannot be in the GUI. They have to be
separate like when using a .pvx file in the server.

The problem is when using a .pvx the viewports are open in the remote
machine, I want them to be open in the client machine.

Best regards,
Leonardo Pessanha

Re: [Paraview] StreamTracer: Combined ReasonForTermination or select individual polylines?

[Andy Bauer]

Hi,

What version of ParaView are you using?

>From my testing it looks like each direction for the stream tracer seeds
has a separate reason for termination in PV 5.3 -- see the attached image.
The domain is a box with length 20 on each side, the velocity is [1, 0, 0],
the seeds are a line source going from min to max of the bounding box
([-10, -10, -10] to [10,10,10]).  The red is for when the maximum
streamline length has exceeded my specified max length of 5 and the blue is
for when the streamline exited the domain.

Is there a case where the same reason for termination value is being used
for multiple termination criteria?

You can use the SeedIds cell data array in the Threshold filter or use the
Edit->Find Data option to select a given streamline from the seed id.

Cheers,
Andy

[Paraview] StreamTracer: Combined ReasonForTermination or select individual polylines?

[Liang Wang]

If the IntegrationDirection is set to BOTH, the two segments of the
streamlines from the seed might terminate for different reasons. For
example, one end might end due to STAGNATION, the other due
to OUT_OF_DOMAIN. When coloring by ReasonForTermination, then the two
segments are colored differently.

My question is: Can a user create more cases of ReasonForTermination so
that we can tell examples like above? Or, how can I select individual
streamlines by its SeedIds (I tried IdsSelection, but that appears to work
for cell/point data only, not for polydata?)

My current solution is to use threshold filter to select lines in the
different regions and apply different solid colors. But it would be nice if
I can handle a few different cases more directly, even if that involves
some coding in C++ or Python.

Joel,
Gridlines really are too light.  I will add a bug.  Thanks for reporting.

They can be changed trivially.  Make a 2d plot.  Properties tab.  Advanced.

Colleagues:

After installing 5.3.0-RC2 and now 5.3.0 (both after using 5.2.0), the Plot

Re: [Paraview] ParaView Web - module twisted.internet error

[Sebastien Jourdain]

Hi Ben,

Those modules are needed and should be shipped with ParaView.

I believe the issue might be in the ParaView project itself not in its
superbuild.
I'm guessing, I messed up a dependency when I split the python code between
python 2+3 and python 2 only. The python 2 one should depend on those
libraries but not the python 2+3 code.

Let me know how I can help to fix that,

Thanks,

Seb

Looking at the superbuild, it appears that when ParaViewWeb got moved
from ParaView into its own repository, the flags that turned on pvweb
got removed and now there's nothing enabling those modules in ParaView's
build anymore. Do those packages need to be shipped with ParaView at all
now? If so, we'll need to add them to the superbuild specifically. If
not, some flag will need to be used to turn them on.

Re: [Paraview] ParaView Web - module twisted.internet error

[Rodnei Couto]

Python modules are different from 5.2 to 5.3

For example, inside* lib/python2.7/site-packages, *the version 5.2 has the
modules *autobahn, zope and twisted*, and the version 5.3 does not.

I tried to copy the twisted and zope modules from version 5.2 to version
5.3, but a got others errors.

By now, I reverted to release 5.2 in production environment.

 Cheers,

 I set up my environment as indicated in http://kitware.github.io/pa
 raviewweb/docs/ubuntu_14_04.html

 My operational system is Ubuntu 64 14_04 LTS.

 When I try to run my start.sh, I get an error:

 pvw-user@cole:/local/pvw-user$ Traceback (most recent call last):
   File 
 "/local/pvw-user/data/pv/pv-current/lib/python2.7/site-packages/vtk/web/launcher.py",
  line 14, in 
 from twisted.internet import reactor, defer
 ImportError: No module named twisted.internet

 i think the twisted is properly installed in my environment, as can
 be seen below:

 pvw-user@cole:/local/pvw-user$ python -c "from twisted.internet import 
 reactor, defer; print( defer ); print ( reactor ) "
 >>> '/usr/local/lib/python2.7/dist-packages/twisted/internet/defer.pyc'>
 


 My start.sh code is:

  #!/bin/bash
 export DISPLAY=:0.0
 /data/pv/pv-current/bin/pvpython 
 /data/pv/pv-current/lib/python2.7/site-packages/vtk/web/launcher.py 
 /data/pvw/conf/launcher.json &


 Can anybody help me? I do not know what else I can do

 Cheers,

Re: [Paraview] Remote rendering to multiple displays

[Mathieu Westphal]

1) ParaView in client server mode with remote rendering enabled, connected
to a pvserver on your cluster. Multiple viewports are not a problem.
2) X ParaView in client server mode with remote rendering enabled,
connected to a pvserver in multi-client mode on your cluster. Multiple
viewports are not a problem.
