Hi, > Did you ParaView come from the openFOAM distribution?
Yes. I tried the src installation from Kitware and installing Mesa correctly was really hard. And I didn't know what values to give to the options in ccmake. So finally I searched "how to install ParaView" and I found that the easiest solution for Ubuntu was `apt-get install paraview`. However this gave me the version 3. I searched how to install ParaView 4.1 and I came across `apt-get install paraviewopenfoam410` I will give a try to Kitware binary installation, I guess should be more easy to install than source. Thank you for your help. PS: Sorry, I pressed 'Reply' instead of 'Replay All', eliminating the list from the Cc. Thank you for bringing it back.

David, Did you ParaView come from the openFOAM distribution? If so I wonder what differences there are in the compilation settings and patch sets for openFOAM's packaged ParaView and the binaries from Kitware. You might try installing the 4.1 binary from Kitware in a different location and comparing that to what you have. cheers David E DeMarle Kitware, Inc.

Yes I do see a pop-up window with the axes at the first moment. But then it turns black and I cannot see the content in it (only in the browser). This pop-up window is however changing its size when I change the size of the browser window (so it is still connected in some way). Does this say something to you?

I am using the same machine as client and server (I access like this: http://localhost:8080/apps/Visualizer/) I changed the quality of the images and there is no difference in the performance (you were right). So, then, what is the bottleneck? Server and client is the same machine and I can move fluently (25-30fps) the models I am opening with ParaViewWeb if I open them just with ParaView. By the way, I have the bad performance in ParaViewWeb (2-5 fps) even if I don't load anything and I only move the axes. Any idea where the bottleneck might be? Anything I can do to find it out? Many thanks in advance for your help.

Are you trying directly on the machine that act as the server, or using a remote client? On what network type? Because usually when I get 2-5 fps, it's because the server is in US and I'm on a basic DSL line in France… I'm not sure that lowering the image quality will change that much. In fact, it already do it by default. I'm still thinking the issue is somewhere else. Anyway to change the quality, you will need to edit the www/apps/Visualizer/index.html […] // Build application function init() { // - viewport $(".viewport-container").empty(); viewport = vtkWeb.createViewport({ session: session, interactiveQuality: 30, stillQuality: 100 }); […] Here is the full documentation about that: http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/api/vtkWeb.Viewport Seb On Fri, Mar 14, 2014 at 12:12 PM, David Torres <[email protected]<mailto:[email protected]>> wrote: Hi Seb, I tested in Chrome 26.0.1410.63 and in Firefox 20.0 (Mozilla Firefox for Ubuntu canonical - 1.0) I got similar results. I also noticed that the selector which changes from "Images" to "WebGL" or "VGL - WebGl" is not doing anything (or at least I cannot see any difference). In any case I am interested in "Images" i.e. rendering in the server. But I would need to low the quality of the images in order to boost the performance. Could you point any instructions that allow me to change the images resolution when the model is being moved? Many many thanks :) PS: Only as an example, in order to clarify: I have tried a mesh with 100 cells and a mesh with 10 million cells. I am getting exactly the same performance for both of them (2-5 fps).

Hi David, you are right, your browser will just display the images that are sent by ParaViewWeb. BTW, which browser+version are you using?

The bad performance is with ParaViewWeb. I am assuming that this is because the quality of the images that is sending is too high (I think the browser is not rendering, only receiving images from the server, am I right?). For the record, I installed ParaView using `sudo apt-get install paraviewopenfoam410` as `sudo apt-get install paraview` was installing the version 3.X and here [1] says that 4.1 or newer is required in order to have ParaViewWeb.

Hi David, The file pw-config.properties is used with the Java version of the launcher. Now with the latest release, we also provide a Python one. => http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/guide/py_launcher Moreover, those configuration files are used to configure a front-end web server that will trigger pvpython command lines. For testing out ParaViewWeb, those front-end are optional. Although, it should be pretty easy to setup the python one by creating a config file that match your local setting. For real deployment read the EC2 documentation that explain how to setup apache to deal with the ws forwarding. Regarding the performances, on a local machine, you should be around 30 fps. So I suspect, you don't have a proper driver for your graphic card. If you have an Nvidia graphic card, try to install their driver. Thanks for letting me know that the script does not work for you, I'll fix it once I have a chance.

I installed Paraview 4.1.0. in Linux using apt-get, and started the ParaViewWeb server using the guide in [1]. I found is working very slow, even in local (2-5fps I think). And I read that I could play with images quality but I don't know where can I change them. Here [2] says there is a file called pw-config.properties which I couldn't find (I used `find / -name pw-config.properties`). I guess it belongs to a previous ParaView version. Then, my question is: where is the properties file in 4.1.0 and what is its name? Will I be able to change the quality of the images there? By the way, I tried the script provided in 'Simple Install' section in [1]. It has a mistake in the line 15. It is: `data = "ParaViewData-v4.1.zip"` and it should be `data = "ParaViewData-v4.1.0.zip"` However, after correcting that, is still failing in line 160 at some point (at least in Linux) and I couldn't find the error.
