No, it doesn't need the path. It will just allow you to pick a name of
known configurations. You can make ParaView aware of the pvsc
configuration by importing it in the "Add Server" option in the
"Connect" dialog.
Actually, ParaView already support specifying the configuration to
connect to on startup as a command line argument. If have a
configuration named "miranda", I can run ParaView as:

> ./bin/paraview --server=miranda

and than will connect using the configuration on launch.

[Paraview] pvbatch and readers with multiple outputs

2014-02-10 Thread Insley, Joseph A.

Hi,

I have a custom reader plugin which has multiple outputs.  From the GUI I can 
load up a data file, and can see the two outputs in the pipeline viewer. I can 
hide or show them independently, choose different representations, apply 
different filters, etc.  I've saved a python state file, and would now like to 
run this in pvbatch.  In my current state file only output 0 is visible.  When 
I run pvbatch this output is not being rendered.  I can call 
GetNumberOfOutputPorts() on the reader to discover how many ports it has (it 
correctly returns 2).  I would now like to call SetActiveSource to explicitly 
set to one of the outputs.  I can't seem to find the correct way to do this.  
Does anyone have any suggestions?

Thanks,
joe

[Paraview] trouble with automatically running multi-core on Windows 7

2014-02-10 Thread Andy Bauer

I'm using ParaView 4.1 from the installers on Windows 7 and I went to

up ParaView I get the output below and it ends up running with the built-in

That is pretty much what I meant by adding support for a "default
server". Only difference being the user could change that from the
settings dialog after which when paraview starts up, it will
automatically try to connect to the "default server" selected, instead
of builtin, complete with all the prompts etc.

Re: [Paraview] Multi-core custom applications

right, but just as the current multicore makes it easy for the user, 
this would all happen automatically as PV starts. So when multicore is 
on, the baked in multicore pvsc dialog is presented as pv starts, the 
user reviews the defaults, and hits OK, and pv starts up connected to a 
server. same as multicore is now, but with the possibility to review the 
run parameters.


I think that even the most basic user will need to modify the number of 
cores used or some encounter performance problems. My sense is that this 
makes it even easier to use than it currently is. at least I find it a 
bit of a hassle to change the number of cores. for example PV 
automatically starts a server using my previous settings, which often 
not what I want. I have to wait for it to start the server I don't want, 
then I have to open up the settings menu, change the number of cores to 
what I do want, then restart it by disconnecting from the current 
server. before I learned that trick I was restarting pv, which was even 
more of a pain. I'm afraid some users don't know about the disconnect 
trick.

works fine for local ones, and it's easy to add dialog entries for

at the pvsc dialog, based on a baked in multicore pvsc, which could
potentially be configured during the build/install? Also internally, for
example in the memory inspector, we currently need to handle the multicore
server differently than any other server (it's actually currently broken for
multicore because of this). even though it's really no different than any
other server, at least judging from the command line displayed in the
terminal.

 Connect to a server and have the front view for everyone with a

Utkarsh or someone else may be able to help you with that. But if you want

Re: [Paraview] Multi-core custom applications

for me every run is different, sometimes I want to use 2 cores others I 
want to use 16. my thinking is that we need a way to set the number of 
cores before the server starts up. It sounds like others are 
encountering situations where they need to tweak the startup parameters 
as well.  and why not just make use of the existing infrastructure for 
specifying those run parameters? The connect to mechanism isn't just for 
remote servers, also works fine for local ones, and it's easy to add 
dialog entries for parameters by pvsc. Perhaps the multicore just starts 
the connect to process at the pvsc dialog, based on a baked in multicore 
pvsc, which could potentially be configured during the build/install? 
Also internally, for example in the memory inspector, we currently need 
to handle the multicore server differently than any other server (it's 
actually currently broken for multicore because of this). even though 
it's really no different than any other server, at least judging from 
the command line displayed in the terminal.

Hi Utkarsh,

I'm wondering what you think about the idea that multicore use the same
mechanism as the normal connect to server? Is there a strong reason for it
to be different? I'm think that when multicore featured is enabled a dialog
defined by an internal pvsc with some basic options such as number of cores
and perhaps pvserver location etc is used. This would allow the user to make
some basic parameter changes and internally make the built in multicore runs
look the same as any other pvserver run. We had discussed this before and
you asked me to file a feature request.

Re: [Paraview] Two Machines - Each one with one monitor - Mirrored and different angles of the same data

2014-02-10 Thread Léo Pessanha

The same server instance.

I don't know how to answer where i am doing the rendering

in my case i want to use pvserver with --multi-clients each one with
different angles

is there other configuration that would give me the same result?

I also found a quick-and-dirty, workaround for openmpi 1.7.2 by manually
adding libdl to the libraries in CMakeCache.txt:



MPI_CXX_LIBRARIES:STRING=/usr/lib64/mpi/gcc/openmpi/lib64/libmpi_cxx.so;/usr/lib64/mpi/gcc/openmpi/lib64/libmpi.so;/usr/lib64/libdl.so

MPI_C_LIBRARIES:STRING=/usr/lib64/mpi/gcc/openmpi/lib64/libmpi.so;/usr/lib64/libdl.so



Maybe a ParaView developer can add libdl to the linking targets for mpi4py
to fix the problem properly.

The error seems related to newer versions of openmpi in combination with

When compiling under openSUSE 12.2 (openmpi 1.5.4) everything works
fine, but under openSUSE 12.3 (openmpi 1.6) and openSUSE 13.1 (openmpi
1.7.2) the compilation fails.

Apparently, in newer versions of openmpi, the wrapper doesn't add '-ldl'
anymore to the linker flags.
See also here:
https://svn.open-mpi.org/trac/ompi/ticket/3103

I'm not sure if this should be fixed in openmpi or paraview, but I would
appreciate any hint on how to fix it.

Best regards,
Armin



It needs to be fixed in paraview - it bundles mpi4py, and mpi4py uses
dlopen(), so mpi4py needs to be linked to -ldl.  Not sure the
appropriate way to fix that in paraview though.

 You need to setup your viewport like that only. so you make a reference
 point and from there you can configure your front screen (easy one). Now
 you use the same reference point place your world screen however you want
 to place it, get its corner points and use those values for the second
 viewport. The reference point will have 0,0,0 values for the coordinates.
 So lets say you have two screens one for the front and other one for the
 floor and the 0,0,0 is at the center of the floor then you will have

 Front:
 LowerLeft="-1 0 -1"
 LowerRight="1 0 -1"
 UpperRight="1  2 -1"

 Floor:
 LowerLeft="-1  0 1"
 LowerRight="1 0 1"
 UpperRight="1  0 -1"

Re: [Paraview] ParaViewWeb

2014-02-10 Thread Ben Bales

Oh! So I didn't realize that example was sharing data between IPython and
Paraview.

I wasn't able to get it to work (some vtk import errors), but when I saw
the  I just got excited and stole that little bit of code out :D,
so maybe I did things wrong.

I just had a closer look, and is that example running traffic through the
IPython web connections?

Let me draw some diagrams (convert this to a monospaced font if it isn't :D)

I -> IPython
P -> Paraview
S -> Secure layer
U -> User

When I have the two servers running separately, and just include an iframe
from one to another, I am doing:

I->U
P->U

What I was asking about doing in the last e-mail was:

I->S>U
P--/

(Where IPython and Paraview both go through the same secure layer). You say
this is something I can set up with Apache, right? When I look at a system
like this, I get scared of rewriting stuff. How does U know to ask S to
route data to P? Is that what this documentation describes:
http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/guide/apache_setup
?

Now I've had a closer look at the script here (
http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#!/guide/ipython),
and I'm wondering, does the Paraview server there use the IPython
communication channels?

[Paraview] Memory leak with time series in XDMF files and

2014-02-10 Thread Simon Stähler

Dear listed ones,

I am trying to generate an animation from a large number of XDMF files
(around 120), containing around 1000 time steps of a 3D dataset.

When saving the animation and switching from time step to time step, I
notice memory usage increasing by some percent per time step, until
finally the application runs out of memory and crashes.

The error pertains, whether I am using XDMF in combination with HDF5
files or with Fortran binaries (both work fine apart from the memory
problem).

I notice that this error had been brought up in the 3.x versions and was
considered to be fixed in 4.0
http://public.kitware.com/pipermail/paraview/2013-June/028664.html
http://www.paraview.org/pipermail/paraview/2012-April/024558.html

Any ideas anyone?

I am using Paraview 4.01 64 Bit on a Debian machine.

cheers,

Simon Stähler

NB. Before testing lots of other stuff … Make sure you disable depth peeling 
the main paraview options. The point sprite shader stuff will never work if 
there’s another shader active.

Sorry, I hit send by mistake,

In this directory,

Can you add line below at the beginning of all of the shaders.  You may have to 
compile ParaView (or plugin again).  This may not fix the problem but it would 
be great if you can provide some
feedback after this.

Re: [Paraview] Multi-core custom applications


Hi Utkarsh,

I'm wondering what you think about the idea that multicore use the same 
mechanism as the normal connect to server? Is there a strong reason for 
it to be different? I'm think that when multicore featured is enabled a 
dialog defined by an internal pvsc with some basic options such as 
number of cores and perhaps pvserver location etc is used. This would 
allow the user to make some basic parameter changes and internally make 
the built in multicore runs look the same as any other pvserver run. We 
had discussed this before and you asked me to file a feature request.

Hi Bruce,

Sorry, I thought replied to your email. In the log you sent me, I do see
that it is stating that point sprites are supported. If you can put a break
point in vtkPointSpriteProperty (at the error line) then we can find out
exactly where the error is coming from.

Re: [Paraview] ParaViewWeb

2014-02-10 Thread Sebastien Jourdain

Hi Ben,

there is several ways to integrate ParaViewWeb into iPython and the
documentation highlight a distributed/in-situ one. (Which is by far the
less obvious one ;-)
In fact, if you are not expecting ParaViewWeb to use directly the in-memory
objects of your iPython MPI engines, you might just deploy a ParaViewWeb on
the side which will naturally allow you to also have it embedded inside
your iPython integration.

For that you will need an apache on the front to do the relay in https/wss.
This should solve the security error.

Regarding the overhead of the server side rendering, we did not wrote any
specific analysis or documentation.
Do you still have render calls when you switch to WebGL on the client side?
Do you have them when you interact with the scene? If so, you can adjust
the JS of the WebVisualizer and disable the camera synchronization of the
WebGL renderer, which will prevent the client to send camera update to the
server. But if you do so, if your data change, your view will revert back
to the original server side camera position.

Hope that helped you in some ways,

Seb

You need to setup your viewport like that only. so you make a reference
point and from there you can configure your front screen (easy one). Now
you use the same reference point place your world screen however you want
to place it, get its corner points and use those values for the second
viewport. The reference point will have 0,0,0 values for the coordinates.
So lets say you have two screens one for the front and other one for the
floor and the 0,0,0 is at the center of the floor then you will have

Front:
LowerLeft="-1 0 -1"
LowerRight="1 0 -1"
UpperRight="1  2 -1"

Floor:
LowerLeft="-1  0 1"
LowerRight="1 0 1"
UpperRight="1  0 -1"

Re: [Paraview] Surface LIC Problem

You could also either use "Extract Block" to remove blocks on which
you don't want to render LIC and then do LIC on the rest. There are
others ways for this subsetting too, based on the nature of your data:
e.g. you could your Extract Selection or Threshold to remove the cells
that you don't want to render LIC on and then render the result.
