[Paraview] Where is the properties file for ParaViewWeb?

Fri Mar 14 14:12:33 EDT 2014

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?

Thanks,

Seb

Thank you Sabastien,

The thing is that in my machine, I have a good performance with ParaView. 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.

Thank you for your help.

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.

Hello,

I am starting with ParaViewWeb. 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.

Thank you in advance for your help.
