[Paraview] Paraview architecture
Hello, I am trying to understand the architecture of paraview and it's dataflow. 1. What kind of rendering happens on client side? What rendering does default paraview client perform? Does it use OpenGL or something? What happens when I drag an image in the client? 2. What kind of data flows between a client, a data server and a rendering server? What's the format? I tried to search the wiki but either I am a bad lurker or it's not there. I am also not sure which mailing list to use, so I'll send this email to both. -- WBR, Boris___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
Re: [Paraview] [Paraview-developers] Paraview architecture
Boris, In the 3D View, and depending on the Render View settings, the client may render the geometry (that is the external surface) of the datasets that it receives from the server using OpenGL, or it can receive and display the images (remote rendering) generated by the server. With the first mode, the interaction is performed locally with some VTK graphical pipelines (camera, interactors, rendere, etc.); when the rendering is performed remotely, the client sends the local camera properties to the server so it can generate images from the correct viewpoint. So depending the mode, the raw surface geometry can be transfered or some compressed images (different compression techniques are available, see Settings / Render View panel). Some other views (eg. 2D plots) may have different behaviour and might require the full dataset to be transfered from the server to the client for display/analysis (in this case, this will not scale of course : eg. if you plot a huge UnstructuredGrid within a Line Plot view after applying the Plot Data filter)...

Also see, http://www.paraview.org/Wiki/Representations_and_Views. It is out of date ever since since 3.14's redesign of the rendering architecture so the names of the classes are different but the overall flow is the same. David E DeMarle Kitware, Inc.

[Paraview] factor in axis label for cube axes
Dear all, How can I change the factor in the axis label? For example, if the x-coordinate is from 0 to 2000 (see the attached picture), the axis label is X-Axis (x10^3), and the values on the axis are from 0.0 to 2.0. If I change the x-axis label it affects the name only, the factor stays the same. I would like to make the coordinates be shown in the original scale: 0 to 2000, without the factor in brackets.

Re: [Paraview] Interfacing with FE simulation using Catalyst
Hello, I tested writing data from the python script, and the data is apparently written correctly when opening the files with Paraview. The issue is only present I try to extract the data in Paraview. I'll continue to investigate both in my code and Paraview. If you have other pieces of advice as to where I could be looking, I would be interested. I will also test if I can reproduce the issue with one of the example.

It should work similarly though. I recently wrote a Catalyst adapter for an unstructured grid. I will run Catalyst Live with that to see how that works. You could try however to save images or entire data from the pipeline script as it is done in the Catalyst examples. A few more questions come in my mind now: - If I understand correctly and if the user wants to pause the simulation, for example when he has only 1 timestep, he would have to do the following steps: * Connect with catalyst in Paraview * Set a breakpoint for time step 0 * launch the simulation Is that alright ? Would it be possible to do this with the play/next frame paraview buttons ? The communication between catalyst and the simulation happens only at time steps. Because of that, Catalyst could only stop the simulation at time step 2. - Looking at the last lines of the blog post concerning pvserver. Is pvserver catalyst enabled by default ? Yes. Does it mean that I can build the following pipeline ? Paraview (local computer) - pvserver (cluster frontal node) - catalyst enabled simulation (cluster nodes) You need to enable MPI to be able to run this. pvserver is the paraview server that does all the rendering, only images are sent to ParaView (GUI).

Re: [Paraview] paraview web issue
Hi Sebastien,
this is for a public deployment but I am testing in the browser while it
locally logged into the system. This server is running ubuntu 11.04,
apache 2.2.22. I hope that this isn't a roadblock.I can't easily upgrade.
your instructions for 14.04 went off OK but in 2 spots I had to find a
work around:
1) proxy_wstunnel had to be installed manually, this went without a
hitch and it loaded up without error
2) in the apache config I had to comment #Require all granted as that
wasn't valid in 2.2
the session id was in the proxy.txt file and had the port number 9100
which I see elsewhere in the logs, so that looks OK.
I'm attaching the launcher config.
the apache config is pasted below.

Re: [Paraview] paraview web issue
Apache 2.2 will probably be an issue as WS forwarding was not properly
supported with url rewrite.
You may need to build Apache yourself on that distribution. The one that
have all the fix and is supposed to work is 2.4.7+.
We have some additional documentation about that part here:

Hi Sebastien,
this is for a public deployment but I am testing in the browser while it
locally logged into the system. This server is running ubuntu 11.04, apache
2.2.22. I hope that this isn't a roadblock.I can't easily upgrade.
your instructions for 14.04 went off OK but in 2 spots I had to find a
work around:
1) proxy_wstunnel had to be installed manually, this went without a hitch
and it loaded up without error
2) in the apache config I had to comment #Require all granted as that
wasn't valid in 2.2
the session id was in the proxy.txt file and had the port number 9100
which I see elsewhere in the logs, so that looks OK.
I'm attaching the launcher config.

Hi Burlen,
Just to make sure, you are performing the install on an Ubuntu 14.04 ?
Are you trying to try it locally first using localhost, or are you
targeting a real deploy with a real host name?
Can you share your config file for the launcher + apache?
(You can do it privately depending on your target deploy / security)
Moreover, can you validate that the session id
c3079f24-73f9-11e4-a023-002590202132
was properly mapped inside the text file that is shared between Apache and
the Python launcher?
Thanks,
Seb

[Paraview] ParaView 4.1.0 with non-system (conda) python
I'm building ParaView 4.1.0 on SL 7.0 (using build script provided with OpenFOAM-2.3.0). I'd like to use python from my miniconda installation at /home/username/miniconda. CMake finds this correctly and in CMakeCache.txt I have: PARAVIEW_ENABLE_PYTHON:BOOL=ON PYTHON_EXECUTABLE:FILEPATH=/home/username/miniconda/bin/python PYTHON_INCLUDE_DIR:PATH=/home/username/miniconda/include/python2.7 PYTHON_LIBRARY:FILEPATH=/home/username/miniconda/lib/libpython2.7.so.1.0 PYTHON_UTIL_LIBRARY:FILEPATH=/usr/lib64/libutil.so but pvpython and the Python Shell in ParaView use the system python from /usr/bin/ This is a problem because matplotlib isn't installed for the system python. I prefer to manage python packages in my miniconda installation. ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview

[Paraview] Cannot get parallelism working in paraview 4.2.0 on our clusters (works with 4.1.0)
Hi, I have recently compiled paraview 4.2.0 on our clusters in the same way I compile with 4.1.0 and am getting some errors. I run pvserver in parallel, and it does not give any weird outputs. I connect with it from my desktop (Mac OS X). I can see in the desktop GUI that four remote servers are connected. I open up a PDB dataset and it is different. I see two “Output” objects in the pipeline browser. This is different than the behavior in 4.1.0. [cid:914AC27C-18D5-42AC-95B6-7668C8B7059B@llnl.gov] I click Apply and get smacked in the face with an error dialog.

However, I actually have been able to reproduce the bug now consistently when using an explicit server/client setup. Here the steps to trigger the disappearance to the color legend: 1) run pvserver (e.g. on the local machine) 2) Connect to pvserver 3) Add a source (e.g. cylinder or sphere) 4) Change the displayed quantities, i.e. the color array, about 5-10 times. Usually I can display each color array at least one time, but when switching several times between them the legend disappears. As said, without using an explicit connection to pvserver I cannot trigger this bug. I attached again two state files, this time using the cylinder source only.

Three state files are attached, simply visualizing 2D cut-plane data: 1. colorLegBug_OK.pvsm: Everything is still working fine and color legend appears as expected. 2. colorLegBug_Fail_0.pvsm: Switched the color array (from 'Z' to 'SourcePV') - color legend disappears for 'SourcePV', but still is present when switching back to 'Z' 3. colorLegBug_Fail_1.pvsm: After some more switching of color arrays, the color legend disappears for all quantities.
