[Paraview] how to extract elevation at a point for a dynamic, implicit surface
I can't seem to work out the proper sequence of filters for the following. I have a 2D triangular mesh with a time-dependent scalar field, say phi. I want to generate a single isoline, say phi=0, which I can do with the contour filter, but then I want to generate a single point by intersecting the isoline with a vertical line, say x=1. Then I want to save the time series of that point, which would look something like t_0, 1, y(t_0), t_1, 1, y(t_1),...,t_n since the x-coordinate doesn't change.

[Paraview] Failed to locate server for newly registered proxy ( animation , AnimationScene2 )
Hi, I've been having an intermittent failures initiating connections to remove servers. That is, I have successfully used paraview in cliient/server mode many times but also had many connection failures. All I get is the error: Failed to locate server for newly registered proxy ( animation , AnimationScene2 ) It shows up after I select the server configuration and click connect (i.e. when it would normally be ssh'ing to the server). Ssh works and I have no trouble connecting to the servers manually with ssh. Paraview crashes after the error message is printed. Sometimes after 3 or 4 failures(restarting paraview each time), the connection will succeed. I'm attaching the servers files. This happens with paraview 3.14.1 and 3.14.0, on mac os x 10.8 and ubuntu 12.10, and on commercial broadband and gigabit ethernet connections. I am using kitware paraview binaries on the client, while the server binaries match those versions and were built by sys admins. Unfortunately we don't have paraview 3.98 installed on the servers yet so I can't test the latest. The configurations I'm using out of the list are 'garnet', 'diamond', and ERDC Utility Server. Same error for all configurations at about the same frequency. Any ideas?

Re: [Paraview] issue with python/qt wrapping on ubuntu: Cannot create GLX context. Aborting.
This crash is apparently due to my attempt at off screen rendering.
Not sure if it's and os mesa problem on ubuntu or just a problem with
the way I was trying to do off screen rendering.

[Paraview] Mac OS X 10.7.3 install failures
Hi, The stuff (paraview.app etc.) in my build tree works but 'make install' fails in part because it's trying to install the vtk python module in $PREFIX/bin/Python which is a link to $PREFIX/Library/Frameworks/Python.framework/Versions/2.7/bin/python (mac OS is partially blind to case) If I manually change the install location to something else like $PREFIX/paraview-vtk-stuff, then things get further but verify_app still fails.

[Paraview] ComputeVisiblePropBounds
Hi,
My simple pyqt gui using vtk is crashing with a seg fault during
parallel runs since updating to 3.14 (master from git repo). The
system is Ubuntu 11.10 (GNU/Linux 3.0.0-11-generic x86_64). I noticed
that right before it crashes it prints ComputeVisiblePropBounds and
found that a simple print statement has (presumably) been left in the
code (see below). 1) Have there been changes to the parallel API that
you would expect would break code which was working under 3.12 and 2)
Should I check out something besides master for now and if so which
tag or branch?
Thanks,
Chris

Hi, Here are a few minor issues installing paraview 3.12 on os x 10.7. The installed app and libraries still work fine 1) Not sure what this one means but the directory is there, though it has a space in the path -- 310/426: fixing up '/Users/cekees/proteus/darwinports/ParaView 3.12.0-468-gacdee51.app/Contents/Frameworks/Python.framework/Versions/2.7/Python' install_name_tool: can't open input file: /Users/cekees/proteus/darwinports/ParaView 3.12.0-468-gacdee51.app/Contents/Frameworks/Python.framework/Versions/2.7/Python for writing (Permission denied) install_name_tool: can't lseek to offset: 0 in file: /Users/cekees/proteus/darwinports/ParaView 3.12.0-468-gacdee51.app/Contents/Frameworks/Python.framework/Versions/2.7/Python for writing (Bad file descriptor) install_name_tool: can't write new headers in file: /Users/cekees/proteus/darwinports/ParaView 3.12.0-468-gacdee51.app/Contents/Frameworks/Python.framework/Versions/2.7/Python (Bad file descriptor) install_name_tool: can't close written on input file: /Users/cekees/proteus/darwinports/ParaView 3.12.0-468-gacdee51.app/Contents/Frameworks/Python.framework/Versions/2.7/Python (Bad file descriptor) 2) Also not sure what this means: CMake Error at /Applications/CMake 2.8-5.app/Contents/share/cmake-2.8/Modules/BundleUtilities.cmake:784 (message): error: verify_app failed Call Stack (most recent call first): /Applications/CMake 2.8-5.app/Contents/share/cmake-2.8/Modules/BundleUtilities.cmake:666 (verify_app) Applications/ParaView/LastConfigureStep/ParaView_OSX_MakeStandAloneBundle.cmake:157 (fixup_bundle) Applications/ParaView/LastConfigureStep/cmake_install.cmake:31 (INCLUDE) Applications/ParaView/cmake_install.cmake:37 (INCLUDE) Applications/cmake_install.cmake:32 (INCLUDE) cmake_install.cmake:118 (INCLUDE) 3) The extension modules for co-processing are not getting installed into the python module. The current setup would requires users to set DYLD_LIBRARY_PATH to the build directory ( ParaView-bin/bin is the only place I can find vtkCoProcessorPython.so). Maybe this relates the install errors in (1)? 4) This one is really trivial, but ... the help message for PARAVIEW_INSTALL_DEVELOPMENT says that that options installs files for plugin development. A more precise message would have saved me some time: installs header files for paraview and vtk development. I don't develop plugins but I use vtk directly. -Chris ___ 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://www.paraview.org/mailman/listinfo/paraview

I'm responding off list because these seems a bit detailed for a regular post--feel free to post it back to the paraview list if you like. Here's a rough idea of what I'm up to. I'm running the IPython notebook server (http://ipython.org/ipython-doc/dev/interactive/htmlnotebook.html). I'm looking for a way to do interactive 3D graphics inside an IPython notebook. I don't claim to know all the details of how the notebook server works but I think the set of connected services looks something like this: WebClient (browser) - Tornado Web Server - IPython Client - IPython Kernel/Hub -1-to-N- Python Engines where - is just some abstract connection (e.g. http, zeromq sockets,etc). This set of processes basically gets started when I start the IPython Kernel on the command line of the server, though I can start engines later as well and connect/disconnect browsers without killing anything else. The kernel starts up a Tornado web server to begin serving up notebook pages, which are JSON files containing executable python code and text cells. When somebody points a browser to a notebook (say localhost:8000/some_path/test.pynb). You can then execute and run the python code in the code cells by doing various things on the webpage representing the notebook (push 'run cell' etc.). The code cells can be executed either on the client python process, or the code can be sent through the hub to be run on a collection of engines also running python (and communicating with each other via MPI in my case). If the code cell is run on engines you can pull objects in the engines' namespaces back onto the client. Now, on the client, if an expression returns an object that implements the interface of an IPython DisplayObject ( http://ipython.org/ipython-doc/dev/api/generated/IPython.core.display.html), then it gets displayed as part of the webpage in an output cell. DisplayObject's can return HTML, JSON, javascirpt, SVG, and range of image formats. I'm attaching a pdf of a simple IPython notebook that has an expression returning a PNG DisplayObject at the very end. In my case, the python engines are running MPI and solve a PDE in parallel. The data structures for the solution all get attached to VTK objects and a visualization pipeline on the engines. Also, Andy Bauer helped me get those VTK objects attached to paraview using the servermanager module a few weeks ago so I can do co-processing now as well. I'm already able to composite, render, and interact with 3D objects using my Qt front end and the python VTK API. I

On Dec 2, 2011, at 2:47 PM, Sebastien Jourdain wrote: Hi Chris, Sorry to get back to you only now, but your question is not that trivial. So what still remains unclear for me is, how do you plan to exchange the data from your visualization pipeline on the engines and PWServer that is needed by ParaViewWeb ? Are you thinking of a VTK file, MPI stage or something else ? What I was thinking at a first thought was: - In your engine once your computation is done, you dump the data somewhere and you launch from your python a PWServer with some initialization script that will load your data so when a web client connects to it, everything will be setup as you expect. As a first cut, I think it would be fine to have the engines write out their data. Andy can correct me if I'm wrong, but I think we could use the co-processing to write just the subset of geometry and field data that we want to display in the notebook. If I understand correctly, with that approach we could then just focus on starting PWServer, reading in the data files, and setting up the communication between tornado and tomcat. For future reference, when we want to move beyond dumping the data, here is how each engine is connected to paraview: A module called vtkViewers has been imported by each python engine and executed the following code: from paraview import servermanager global globalController, newGlobalController paraview.options.batch = True paraview.options.symmetric = True pm = servermanager.vtkProcessModule.GetProcessModule() globalController = pm.GetGlobalController() ... In addition to this bit, each engine has attached it's mesh and field data arrays to the proper VTK containers and set up a parallel visualization pipeline. It can potentially also read in a co-processing script to set up additional visualization. I was hoping that this setup would eventually allow us to start a PWServer and attach it to the pvserver which is directly connected to the VTK objects in memory on each engines. - On the ParaViewWeb side (tomcat web app) you will have to patch the code so it won't prevent you to connect to a process that was not started by itself. (I can help you with that, it should be pretty simple) Thanks, that would be very helpful. - Find a way to forward the HTTP requests from tornado to tomcat I'll look into that. I'm going to visit the IPython notebook developers next week and can get some help on working with tornado. I think it will help if I can get the standard ParaViewWeb setup working. But once again, I'm not sure I get the right picture of your setup and depending on how your VTK processing is done, other solution may be possible. Hope this provides some hints on your wondering, Seb PS: For your later mail did you get the source form here (http://paraview.org/ParaViewWeb.git) which is not github ? Yes, sorry, I got it from paraview.org. PS2: Most of the documentation is available here: http://www.paraview.org/Wiki/ParaViewWeb I've been working from that documentation. Somewhere on the list somebody mentioned upgrading to activemq 3.4 so I did too. I should only need activemq cpp libs, paraview, and PW server to successfully build and make tests, right? Or do I need to install and startup activemq and tomcat? Thanks, Chris On Fri, Dec 2, 2011 at 3:34 PM, Chris Kees cek...@gmail.com wrote: Hi Seb, I thought I'd go ahead and try to install PWServer.

[Paraview] installation of paraview and vtk into system python's site-packages

[Paraview] SC10 CoProcessing example
Hi, I've got a few questions about the python example, CoProcessingExample.py. First, FYI, when downloaded to my mac the script contains indentation errors so python can't parse it. Don't know what is going on (maybe our firewall is trying to prevent us from using python by messing up the indentation!). Second, my interepreter couldn't find the mpi module even though my PYTHONPATH etc were set up as on the wiki. I use mpi4py to manipulate mpi anyway, so I just modified the script to use it instead. Will that be OK in general or do I need to track down the mpi module in order for the coprocessing library to work correctly? In terms of using the example, I constructed an image source in paraview and colored it with the pointData, then saved the state script. I had to get some of the name strings straightened out but the example appeared to run and generated a sequence of png files. Does anybody have a simpler state/coprocessing script for that example that I can use for learning purposes? The next thing to do is expose my solver's vtk data structures to the co-processor and generate a coprocessing script for it. I'm afraid given my weak understanding of what is going on, generating the state script from one of my xdmf data sets and trying to get it to work inside the coprocessing is going to be difficult (our i/o and existing vtk visualization are completely independent). It might be easier if I new how to wrote the state script by hand to execute something very simple. I've got lots of vtk pipelines set up for the data under our current approach to runtime vtk viz so I was hoping I could just paste in something similar into the state script.

Re: [Paraview] install vtk headers and libs from paraview?
Thanks, that worked. With that approach I still have to do a build of VTK and and a build of paraview (which also builds its own vtk) so I get two copies of the vtk libraries installed. I was hoping to go one step further and have paraview use the version of vtk I use for everything else. It's not that big of deal though. I can live with two sets of vtk libraries.

Re: [Paraview] qt 4.5 64-bit mac os x
Sean, I was/am using the cvs source (updated this morning). I think the problem was just that I forgot to apply the VTK-bug-7818-patch.txt. I appear to have a working 64-bit paraview with a 64-bit python interpreter running from the build directory now. The install target still tries to put a stand alone bundle in / Applications, regardless of the value of CMAKE_INSTALL_PREFIX. If I set the DESTDIR environment variable, then it tries to put it in DESTDIR/CMAKE_INSTALL_PREFIX, which means I get something like /opt/ local/opt/local. Does anybody know how to properly get a paraview executable in CMAKE_INSTALL_PREFIX? I don't really need a bundle, just one that uses the libraries and binaries installed in $CMAKE_INSTALL_PREFIX/lib/paraview-3.5. I suppose I could set CMAKE_INSTALL_PREFIX to ' /' and DESTDIR to /opt/local.
