Re: [Paraview] Build ParaViewWeb on windows

[Sebastien Jourdain]

Replace the following CMake lines

# ParaViewWeb on Windows needs win32api which is not provided by default
# For now the default behavior would be to disable it on Windows build
if (WIN32)
  set(PARAVIEW_ENABLE_WEB OFF CACHE BOOL "" FORCE)
else()
  cmake_dependent_option(PARAVIEW_ENABLE_WEB "Enable/Disable web support" ON
"PARAVIEW_ENABLE_PYTHON" OFF)
endif()

with the following =

# ParaViewWeb on Windows needs win32api which is not provided by default
# For now the default behavior would be to disable it on Windows build
if (WIN32)
  # set(PARAVIEW_ENABLE_WEB OFF CACHE BOOL "" FORCE)
else()
  cmake_dependent_option(PARAVIEW_ENABLE_WEB "Enable/Disable web support" ON
"PARAVIEW_ENABLE_PYTHON" OFF)
endif()

Then you should be good to go.

Re: [Paraview] Build ParaViewWeb on windows

[Sebastien Jourdain]

Try to add that path to the following environment variable:

set PATH=%PATH%;C:\Python27\Lib\site-packages\win32
set PYTHONPATH=C:\Python27\Lib\site-packages\win32

If that doesn't work, you will have to search on the net on how to make
Twisted works on Windows.

Good luck,

Can you change the remote X setting to have a larger resolution?

Re: [Paraview] Zooming through the ParaViewWeb API

[Sebastien Jourdain]

Scott is right, the x,y values are normalized, so depending on your screen
size if your image is 1000 pixel wide and you want to reflect a move of 10
pixel, you should send a x of 10/1000=0.01.

Re: [Paraview] Cross Site collaborative visualization

[Sebastien Jourdain]

Hi Brock,

Some answer are provided below.

I’m looking at a need to allow off campus and public (k-12, other schools)

What kind of data? Are you expecting dynamic pipeline, or some kind of
constrained exploration could be a possibility?

ParaViewWeb can definitely share the same server and provide collaboration
features, but for that you will need to setup a front-end that will allow
connection to existing/running session. There is nothing complex about
that, but ParaViewWeb only focus on the visualization aspect not on any
specific deployment configuration like collaboration or authentication
system.

ParaViewWeb can certainly provide the most advance access to your data but
will require some backend infrastructure and integration work.
We also have other approaches that could be more reasonable for a school
deployment which will put almost no constraints on the existing
infrastructure (No need for server side GPU and so on...) and provide good
capabilities of data exploration and visualization in a Web context.

ParaViewWeb is definitely part of ParaView and therefore will be supported
for the coming years with improvement expected.

We will be presenting at SC15 (Super Computing) on our booth our work in
Web Visualization. This will include ParaViewWeb improvements and the
announcement of that other project.

But we can certainly setup a meeting before that and talk in more details
about your goals and what that other project could do for you.

Re: [Paraview] LiveArticles example with paraview 4.4

[Sebastien Jourdain]

Hi Livia,

The error seems related to the following issue:

http://localhost:9442/ws [HTTP/1.1 400 This server only speaks WebSocket
subprotocols wamp.2.json.batched, wamp.2.json 10ms]
Connection could not be established. embed.html:134:25

I'm not sure to understand why that could be, but I was wondering if you
could try to run the WebVisualizer to see if that works as it's the part
that get actively developed while the rest are just sample code base that's
meant to help the community to build their own code base.

Moreover, if you could share your launcher configuration, that could be
useful.

Thanks,

Seb

Re: [Paraview] pvpython and H5Part Issues

[Sebastien Jourdain]

Hi Amit,

inside pvpython you should do the following

from paraview.simple import *
LoadDistributedPlugin('H5PartReader', ns=globals())

Then you should be good.

Re: [Paraview] ParaViewWeb on remote machine w/ port forwarding

Hi Ken,

One thing to be aware is that Apache 2.4.6 has a bug in the rewrite module
for web socket. Hence the need to have 2.4.7+.

Before doing much debugging, can you check and report back here what
 version of Apache you're running on the web-facing servers?

Re: [Paraview] ParaViewWeb JS API: get camera position

I don't see any but you can add your own method such as

@exportRpc("viewport.camera.get")
def getCamera(self, view_id):
view = self.getView(view_id)
return {
focal: view.CameraFocalPoint,
up: view.CameraViewUp,
position: view.CameraPosition
}

Re: [Paraview] ParaviewWeb - Python Script

[Sebastien Jourdain]

Hi Ruggiero,

It is definitely possible with ParaViewWeb. Either you embedded your
initialization code within the Python Script that define the ParaViewWeb
server or you can extend the pv_web_visualizer.py one to add a new argument
which could be the path to the script you want to run at initialization
time and then you make sure you process that arg and run that script before
starting the Web server.

If you think that feature should be part of the Visualizer application,
then you can submit a pull request on our gitlab and assign me as reviewer.

Happy new year!

Seb

Re: [Paraview] ParaViewWeb

Just catching up here...

ParaViewWeb is not built on Windows by default. It is possible but as it
require an external dependency, we didn't make the jump on building it for
Windows in our SuperBuild.

Re: [Paraview] Paraview Web communication with external program

[Sebastien Jourdain]

Hi Ruggiero,

I'm not sure I understand each of the pieces here. But I'm pretty sure it
is possible.

For example, your second (python?) script could connect using the autobahn
library with the server of the visualizer app to customize some settings.

Re: [Paraview] ParaViewWeb issues

[Sebastien Jourdain]

Hi Amit,

I'm not familiar with the system package of ParaView on your OS, but
usually the Python dependencies are managed within ParaView.

So either you have a conflict between your system python library and the
one embedded inside ParaView,
or if that package is properly managed by the system, that mean you are
missing some python library.

For the later use case, I've attached what are required by ParaViewWeb to
work.

Re: [Paraview] ParaViewWeb issues

[Sebastien Jourdain]

Cool glad that worked...

Autobahn evolved to use crossbar.io, but we are not ready yet for moving to
crossbar.io on the server side hence the 'old' version.

Re: [Paraview] WebSocket connection failed: Error during WebSocket handshake: Unexpected response code: 404

Hi Gabriel,

do you mind sharing (privately if you prefer) your apache config as well as
your launcher config?

Thanks,

Re: [Paraview] WebSocket connection failed: Error during WebSocket handshake: Unexpected response code: 404

[Sebastien Jourdain]

Your launcher config should be as follow:

"sessionURL": "ws://${ApacheHost_or_IP}:8088/proxy?sessionId=${id}",

Assuming that /var/visor/mapping/proxy.txt is the same file (network
shared) with /mnt/nfs/mapping/proxy.txt.

Thanks for your feedback and I'm glad that's working as expected now.

The updated version of that documentation is now available here:

Re: [Paraview] WebSocket connection failed: Error during WebSocket handshake: Unexpected response code: 404

[Sebastien Jourdain]

localhost should work for the launcher unless you have several network
interface.

Moreover, you can use the launcher to issue ssh command to start paraview
on other machines, in which case the host, is not the paraview one.

Would it make more sense if ${launcher_hostname_or_ip_or_localhost}?

Re: [Paraview] libGL error: failed to load driver: swrast

[Sebastien Jourdain]

Hi Rob,

Are you planning to have a GPU on the server, or just a CPU?
If you are targeting just CPU, you will have to build ParaView with OSMesa
and llvmpipe (Which will provide somewhat slow rendering).
Here is a documentation on how to build both of them:
http://kitware.github.io/paraviewweb/docs/guides/os_mesa.html

Re: [Paraview] libGL error: failed to load driver: swrast

[Sebastien Jourdain]

Hi Rob,

Is it a headless machine or not? The pvw-setup is targeting a regular
desktop computer with GPU and proper OpenGL drivers.

The setup that I was mentioning earlier is a special setup when no GPU is
available hence the need to build ParaView specifically for your hardware.

So my question is (before trying crazy stuff), where are you trying the
demo on? (Hardware and software information)

Yes the link I gave you is the good one for that:

http://kitware.github.io/paraviewweb/docs/guides/os_mesa.html

We have EC2/GPU images that are public and fully setup if you want to.
I can give you the ami-xxx names if you want to. (Still have to publish
that in a proper documentation online...)

Seb

PS: BTW with vagrant and a VM with no GPU the performances will be pretty
poor.

The public AMI are below. Just beware that they require GPU. Otherwise, I
agree with you, a docker image and/or some ansible playbook would be nice.
I am not sure I will get to it that soon, so if you happen to build any of
that and are willing to share with the community, then let me know, that
will be really nice.

Re: [Paraview] building Paraview with OSMesa from source on Linux

[Sebastien Jourdain]

What did you set in CMake for your install path? Maybe you let the default
be /usr/local or something like that which you don't have access to? If
that's the case, just set the path to be something else where you can write.

Re: [Paraview] Compile PV with Paraviewweb on Windows

Hi Daniel,

We are going to work on the Windows support in June for the next release of
ParaView 5.1+.
At the moment, building ParaViewWeb for windows won't be easy. But once we
iron out the process, it will be back by default in our binaries.

Re: [Paraview] Mesa compilation

[Sebastien Jourdain]

Hi Daniel,

here is an updated version of the documentation.
We are in the process of migrating the documentation and code base. Once it
will be done the later will be the official one.

http://kitware.github.io/paraviewweb/docs/guides/os_mesa.html

Moreover, if you are on linux and you are using the latest ParaView, you
can use our binaries as they embed the llvm libraries.
When running ParaViewWeb, you just need to add an extra argument
--mesa-llvm.

Re: [Paraview] Setting up Paraview Web on a headless Fedora server with GPU

[Sebastien Jourdain]

You were on the right track with DISPLAY=:0 but I'm wondering if you setup
a "virtual" monitor or if your "paraview" user is auto logged in a X
session or if it stuck at the "login" panel?

You can find some information about the virtual screen here: (Search for
"Screen")

http://kitware.github.io/paraviewweb/docs/guides/graphics_on_ec2_g2.html

And for the autologin if it is needed. (Note on EC2 the user start X hence
no need to login...)

Re: [Paraview] Problem importing vtk inside pvpython

[Sebastien Jourdain]

I think you have VTK installed on your system which conflict with your
ParaView one. Hence the segfault inside ParaView.

Otherwise nothing should prevent you from doing pure VTK code in ParaView
as long as you are aware of the possible issue when running remotely and/or
in parallel.

Re: [Paraview] Setting up Paraview Web on a headless Fedora server with GPU

[Sebastien Jourdain]

You are getting really close...

Basically you have the ParaView process that properly started at the
request of the client and waits to it to connect, which never happen.

Usually that mean, you have a mistake either in your Apache config and/or
in your launcher.

Could you share your Apache virtual host with your launcher config along
with the URL the web client connects to?

Re: [Paraview] Setting up Paraview Web on a headless Fedora server with GPU

[Sebastien Jourdain]

Glad to hear you figure it out.

You can setup Apache to use https/wss and just redirect to ws:// internally.

Usually one core is enough especially if you have ParaView build with some
SMP/tbb. MPI will introduce some overhead. Unless you need many machine for
your model to fit in memory.

If you need to interface a cluster, you also can to that with some
mpi-pvserver connecting back to your pvpython client.
But that will be probably another thread. ;-)

Enjoy,

Seb

Re: [Paraview] ParaviewWeb with remote, distributed data

[Sebastien Jourdain]

Hi Sven,

1) Yes, assuming you are using pv_web_visualizer.py you can look here:

https://github.com/Kitware/ParaView/blob/master/Web/Applications/Visualizer/server/pv_web_visualizer.py#L18-L28

2) The server can push notification to the client. Need to slightly edit
the client and server to match your needs.

Re: [Paraview] ParaviewWeb with remote, distributed data

[Sebastien Jourdain]

The ParaViewWeb_Design you found is 5 years old but some users are still
using it.
=> The future matching doc would be:
http://kitware.github.io/paraviewweb/docs/guides/architecture.html

The second link should still be somewhat ok until ParaView 5.1 (Valid till
June 2016).

As starting June (~July), the old documentation should disappear and only
the http://kitware.github.io/paraviewweb will be the official one. But as
we are transitioning both documentations are available.

Re: [Paraview] ParaviewWeb with remote, distributed data

[Sebastien Jourdain]

Hi Scen,

that's a correct way, but I'm not sure to know why it is that much slower.
Wondering if all the pvserver are fighting for the same GPU and hence
waiting more than anything... ?
You may be able to change the remote rendering threshold to make sure only
pvpython is doing the rendering.

Re: [Paraview] Paraview Web 5 show Widget‏

[Sebastien Jourdain]

Hi Michal,

That feature is not currently available as a protocol on the Python side.

It is possible to add it back, but will take some time especially since we
have other focus regarding the Visualizer improvements...
Moreover, we dynamically generate the UI, which will make the 3D widget
toggle a little be more trickier compare to a adhoc UI like the one that
was done for PWApp.

Are you trying to enable it for a custom application, or are you looking
for having that feature in the ParaViewWeb Visualizer?

Re: [Paraview] Connect ParaViewWeb to Catalyst

[Sebastien Jourdain]

Hi Sven,

Live catalyst connection require a specific socket connection to the
in-situ process with some special handling.
We did not (yet) wrote the Python code to perform that specific action for
ParaViewWeb so it could be triggered by the web client or configured via an
argument at launch time.
I don't see any reason why this couldn't work, but as for now, I also don't
know an easy step to do it without spending time doing it myself.

Re: [Paraview] Connect ParaViewWeb to Catalyst

[Sebastien Jourdain]

Hi Sven,

I am not aware on any specific developer documentation for Catalyst on the
ParaView side (but I haven't worked on that subject for years), although
Utkarsh or Andy might know.

Usually looking at the code and redoing it in the Python world is what is
required, but as I said, I'm not sure of what it means since I don't know
that code anymore. ;-)

For the timeframe, I can't tell (meaning I don't know), but we can still
try to help you or implement the missing piece via support contract if that
make sense on your end.

Thanks,

Seb

Glad to ear that you managed to get something going. If you feel like
sharing your code, we might be able to provide some integration into
ParaView and/or ParaViewWeb proper.

Re: [Paraview] Connect ParaViewWeb to Catalyst

[Sebastien Jourdain]

Hi Sven,

What you did is what I was planning to do. Maybe cleaner, but that's it. So
the end integration could be slightly different, but the core will be the
same.

On a side note, we will never call a "Qt" code from Python. As we are note
expecting the GUI to be build for ParaViewWeb.

Re: [Paraview] Connect ParaViewWeb to Catalyst

[Sebastien Jourdain]

Hi Sven,

Thanks for your feedback. I'm even surprised to see my name on that Python
file. I definitely forget about it and I'm not even sure to know what it is
doing, but it is probably a good start.

Regrading your comment on ./VTK/Web/Javascript/Widgets/CatalystBrower/*, it
is not meant to be used for that purpose.
It was written to build some visualization tools of data generated via
Catalyst. (https://datascience.lanl.gov/data/papers/SC14.pdf)

If you want to see some progress on that web code you can look at
http://kitware.github.io/paraviewweb/ and
http://kitware.github.io/arctic-viewer/ for concrete application.

ParaViewWeb - Visualizer is meant for that. Although, selection is not
implemented currently.

http://kitware.github.io/paraviewweb/applications/

But that version of Visualizer require ParaView/master.

Otherwise an older version of Visualizer is provided along with ParaView
binaries (except for Windows).
You can find documentation on it here:

You seem to have a very old node and npm.

The npm package is here: https://www.npmjs.com/package/pvw-visualizer

Re: [Paraview] ParaView over the internet

[Sebastien Jourdain]

BTW, if you plan to run ParaView in a VM, the rendering performance will be
pretty low unless you properly setup the VM to use a GPU with the proper
drivers.

Re: [Paraview] PV Web scrollwheel for zoom, wrong legend

[Sebastien Jourdain]

1) Yes, the client code should send the proper event to the server. But
that event might not be properly handle by the ParaView backend while it is
for VTK.

Look at ${pv_src}/Web/Python/paraview/web/protocols.py
 #ParaViewWebMouseHandler
vs ${pv_src}/VTK/Web/Python/vtk/web/protocols.py
#vtkWebMouseHandler

it seems the paraview one is missing:

  if event.has_key("scroll"):
pvevent.SetScroll(event["scroll"])

Just add it to your paraview python file.

2) The WebGL viewer is fairly limited so I don't see much thing that can be
done to fix it. But we are working on a version of VTK on the client that
will allow to have very similar rendering results between the server and
the client.
Once VTK.js start supporting scalar bars, we'll start migrating the code to
use VTK.js for local rendering.
Otherwise, you can always try to fix the code, but first make sure the
server is also properly sending the range of your scalar for building that
scalar bar before trying to fix the client code.

Re: [Paraview] load plugin through python scripts

[Sebastien Jourdain]

you need to provide your globals to LoadPlugin, so it can add H5PartReader into
the main scope.
Otherwise, you will need to use the full path which should be something
along that

servermanager.sources.H5PartReader


def LoadPlugin(filename, remote=True, ns=None):

"""Loads a ParaView plugin and updates this module with new constructors

if any. The remote argument (default to True) is to specify whether

the plugin will be loaded on client (remote=False) or on server
(remote=True).

If you loaded the simple module with from paraview.simple import *,

make sure to pass globals() as an argument::


LoadPlugin("myplugin", False, globals()) # to load on client

LoadPlugin("myplugin", True, globals())  # to load on server

LoadPlugin("myplugin", ns=globals()) # to load on server


Otherwise, the new functions will not appear in the global namespace."""

Re: [Paraview] ParaviewWeb security

[Sebastien Jourdain]

Hi Sven,

We do take security seriously.  Several actions have been made to make the
exposed protocols more secured.
It is true, that legacy protocol like ParaViewWebPipelineManager does not
check for code injection. But that protocol is deprecated and will be
removed for the next ParaView release (5.2).

In the current ParaViewWebProxyManager we do check that the user is allowed
to create the given requested proxy.

@exportRpc("pv.proxy.manager.create")
def create(self, functionName, parentId):
"""
Creates a new filter/source proxy as a child of the specified
parent proxy.  Returns the proxy state for the newly created
proxy as a JSON object.
"""
name = self.validate(functionName)

if not name:
return { 'success': False,
 'reason': '"' + functionName + '" was not valid and
could not be evaluated' }

   [...]

Regarding the access outside of the --data-dir we are preventing the user
from listing any file outside of that directory

if not currentPath.startswith(normBase):
print "### CAUTION =="
print " Attempt to get to another root path ###"
print "  => Requested:", relativeDir
print "  => BaseDir:", normBase
print "  => Computed path:", currentPath
print "### CAUTION =="
currentPath = normBase

Although, it is true that we are not guarding the "open" function which is
a mistake and it will be address right away.

Regarding your question, ParaViewWeb tend to be deployed on secured
environments (intranet and/or behind firewalls) but could be deployed on
the internet if specific actions are taking care. The authentication should
be delegated to your infrastructure and your infrastructure should be
responsible of launching the ParaView process under the user privilege. Our
Python launcher is provided as an example and for quick demos in a secured
environment but can not be considered secured. Since we delegate the
launching and the authentication to your infrastructure, you should also
provide a mechanism to share in a secure way the secret key that was used
to launch your application. The goal of that secret key is to prevent any
user that could have guessed your session ID (endpoint URL) to connect to
your dedicated WebSocket.

Then, after that, we are assuming some kind of user responsibility as we
seems to trust them enough to use server side resources. Specially as they
can still bring down the machine by filling up the memory and/or using all
the CPU via complex geometry/pipeline processing. In which case, it will be
fairly hard to prevent such behavior.

Regarding your last question, we do not provide any commercial alternative
but we provide support which could be used to improve our current Open
source solutions to match your expectations or create new products which
will be your property.

Seb

Re: [Paraview] VTK File Format Question

[Sebastien Jourdain]

Hi Jeff,

the points coordinates are implicit which mean that once you defined
your grid by its size/spacing/origin, your are fine. And the only
thing that is missing is the data that you try to show. Those data can
be located at each point of the grid or at the center of each cell
(cell: small boxes that compose the big one). Typically, this could be
the color that you want for them. But usually, it represent an
information (temperature, pressure, ...) and we use a lookup table to
convert those scalar value into a color, by setting the lookuptable
the way we want in term of color and alpha.

Re: [Paraview] [paraviewweb] trouble with paraviewweb on windows

[Sebastien Jourdain]

Hi Pjotr,

few comments before getting further for solving the problem that you are facing.

As Utkarsh said we didn't try to have a Windows server for ParaViewWeb
and as a client IE is not the best browser available specially with
the JavaScript renderer. In fact, if the targeted client is IE, you
should use the flash renderer for better performances. For now, the
best client platform is Firefox.

Regarding your problem on Linux, did you get through the FAQ
(http://www.paraview.org/Wiki/ParaViewWeb/FAQ) ?
Which version of ParaView did you use to compile ParaViewWeb ?
Do you manage to make that ParaView rendering working ? To try it,
launch the pvpython and run the following lines

from paraview.simple import *
Sphere()
Show()
Render()

I let you get back to us for more feedback if none of this help you.

Seb

Re: [Paraview] [paraviewweb] trouble with paraviewweb on windows

[Sebastien Jourdain]

Hi Pjotr,

I get a similar behavior from someone else which had some network
configuration issue on the ParaViewWeb server computer. To check if
you have the same problem, you can try to start a visualization
session with PWApp and go to PWService to "Quit" that running session.
And if you get an error, this should help you to identify the
miss-matching network configuration on that computer.

Re: [Paraview] Some tests and questions about PV 3.10.0-RC1

[Sebastien Jourdain]

Hi Richard,

I've just talked to Rob about your problem and explained your point.
Rob is going to report a bug for that.
One solution we were thinking of is when several files are selected in
the OpenFile process, if we already have define a reader for a given
extension, we reuse that same reader and ask for the reader type only
for new extension where concurrent reader exist.

What do you think ?

Re: [Paraview] Multiblock dataset, ghost nodes and problem with rendering contours with opacity

[Sebastien Jourdain]

Hi Mohamad,

Did you add a data array "GhostLevels" to specify for each cell its
ghost level ?
It's an unsigned char data array where the values are the depth into
the next block for of each cell.
By that I mean:
- 0 is the cells of the current block
- 1 is the set of cells that share points in the current block and the
neighbor one.

Re: [Paraview] Multiblock dataset, ghost nodes and problem with rendering contours with opacity

[Sebastien Jourdain]

Hi Mohamad,

I thought you were working on an unstructured grid. As it is not the
case you shouldn't bother with the array that I talked earlier.
But you should provide the information that each piece is a part of a
whole system and not a set of whole system shown in the same 3d world.

Did you try to specify the WholeExtent to be the Whole system extent
and not the piece one ?

Hi,

you forget to call Render() before and after the ResetCamera().

Re: [Paraview] Visit Reader crash

[Sebastien Jourdain]

Hi Guys,

to give you some heads up, the issue that you are facing where the
client is not working with a server which has a different proxy
definition set, such as the SILO and CGNS readers will be solved in
ParaView 4.

Now the client will get the Proxy definition from the server, so no
more mismatch in client/server capability.

Seb

PS: I don't have any time frame for it, but that code will be
available in the coming weeks to the community...
PS2: An announcement will be made to give more information about that
version anyway...

Re: [Paraview] Getting line data into Paraview 3.10.0

[Sebastien Jourdain]

is it because you are using "\" in your path ?
It seems that your command to open the file is wrong..

Re: [Paraview] Updating an Information Only Property

Hi Brian,

on the proxy itself, you can call either of the two methods
UpdatePropertyInformation() /
UpdatePropertyInformation(vtkSMProperty*)

Re: [Paraview] Getting a raytraced picture from Manta

[Sebastien Jourdain]

Hi Sohail,

you should just close the default 3D view and create the Manta one by
clicking on its button.
Then any object that you create will be shown in that raytracer view... And
with the latest implementation, you don't need a remote server anymore.

Re: [Paraview] Getting a raytraced picture from Manta

[Sebastien Jourdain]

Hi Sohail,

if you are using 3.8.0, it is true that you will need to start a server
(pvserver) and connect to it to allow manta to work "properly" with
ParaView. You don't need to run in MPI, but it has to be in a different
process than the client. (I mean no built-in mode)
On the other hand, once you get connected to that pvserver (in localhost for
example) you will have to load the plugin on both side (client+server). Once
this is done, you should be able to close the 3D renderer and create a new
one based on Manta.

For the crash part, the best person will be Dave that I cc. But as he is
traveling, he might not be able to answer to you right away.

Re: [Paraview] Information Only Property Parameters

Unfortunately that's the way you have to do it. Or the other way is to
use GatherInformation() but it won't be much better.

Re: [Paraview] Information Only Property Parameters

Hi Brian,

could you send the (part of) XML proxy definition and the piece of
code you are calling to that proxy to make that push...
So I could be sure that both side are corrects.

Thanks,

Seb

Re: [Paraview] Information Only Property Parameters

[Sebastien Jourdain]

Hi Brian,

I'm not sure to understand your UI and the way the things are.
It might be overkill, but if you want to express those dependency, you
can create your own domain based on what it is filled so far so at
start only TypeList will be available, then "TypeList + DataTypeList"
and then "TypeList + DataTypeList + DataList"
Other than that, I don't know if it is possible to change the order...

[Paraview] ANN: Upcoming changes to ParaView Server Manager

[Sebastien Jourdain]

Folks,

For those of you who haven't follow the topic in the
paraview-developers mailing list here is a quick summary on what's
going on in the coming weeks.
We've been working for a while now on restructuring the Server Manager
of ParaView to make it more efficient as well as allowing it to
support collaborative workflows.
The API has undergone major changes and may cause some minor rewrite
of your own code. Before we merge these changes to master, please try
out the Collaboration branch with your code and let us know if you
experience any issue.
Please see below for the details on how to checkout the Collaboration branch.

Thanks for your support,

Seb

= From the ParaView-developer list ===

Following up the mail from Utkarsh on the changes to ParaView Server Manager :

http://public.kitware.com/pipermail/paraview-developers/2011-February/000951.html

We finally push our branch to the stage. That branch will only be
merged to master in the coming month.
But if you have developed a plugin or any code based on ParaView and
you want to test it against
that major update, please follow the coming instructions and don't
hesitate to send us your feed back.

In order to fetch our ParaView branch from stage, you will need to
execute the following command line:

$ git clone --recursive git://paraview.org/stage/ParaView.git -b Collaboration

Then, as any regular ParaView source directory, you should be able to
configure and build it.
As some directory and kit renaming occurred, you may need to update
the name of the ParaView library that you are linking against. Now the
ParaViewCore package which used to be called "Servers" contains the
following kits:
vtkPVCommon, vtkPVClientServerCore, vtkPVServerImplementation,
vtkPVServerManager, vtkPVVTKExtensions.

Please remember, these do not affect 3.10 or even 3.10.1. These will
make into the
official ParaView 4.0 release, nothing sooner.

Re: [Paraview] ANN: Upcoming changes to ParaView Server Manager

[Sebastien Jourdain]

Hi Takuya,

I'm glad that you gave a try and you managed to make your plugin work.
Moreover, thanks for that "cheat sheet".

Here is my feedback about it:

> OLD: pxy->Set/GetServers() (where pxy is a vtkSMProxy)
> NEW: pxy->Set/GetLocation()

Yes

> OLD: pxy->Set/GetConnectionID()
> NEW: pxy->Set/GetSession()

Yes, but those lines should simply be removed as the session is set on
the Proxy at its creation, therefore there is no point in doing it
twice.

> OLD: pxy->GetID()
> NEW: VTKOBJECT(pxy) (a stream operator in client-server stream)

Yes

> OLD: pm->SendSteram(this->GetConnectionID(), this->GetServers(), stream)
> NEW: this->ExecuteStream(stream) (where this is a vtkSMProxy)

Yes

> OLD: pm->SendStream(pxy->GetConnectionID(), pxy->GetServers(), stream)
> NEW: pxy->GetSession()->ExecuteStream(pxy->GetLocation(), stream)
> (where pm is a vtkProcessModule)

Yes, but as you did it previously you can also do that
NEW2: pxy->ExecuteStream(stream)

> Also, what I noticed so far are
> * CoProcessing module does not build due to some missing headers.

I'm going to look into that and fix it. Thanks to have notice it.

> * ParaViewCore/ServerManager/vtkSMDataSourceProxy.{cxx,h} are orphaned
>  (have no reference from other sources or CMakeLists).

Yes, I was planning to remove it. Are you using it ?

Thanks again for those valuable comments,

Seb

It is intended, specially if your are not inside the vtkSMProxy class
implementation.
It is more a helper method that use the proxy session and location to
send and execute the stream that may not be related in any other way
to that proxy.

thanks,

Seb

Re: [Paraview] ANN: Upcoming changes to ParaView Server Manager

[Sebastien Jourdain]

Hi Folks,

I've push some new code in the same stage branch that should fix the
plugins (coprocessing, manta, EyeDomLighting...) and some other minor
bugs.

Sven also provide me some feedback that may be interesting to share:
For those with custom readers that internally use FileSeriesReader:

* Replace in servermanager XML:



 with



Moreover, you can look into the git history and see what I did change
to make those plugin work.
The manta one could be interesting for some of you. (git show 2aa56d)

Enjoy,

Seb

Hi Sven,

I just give a try with the archive you provided and I get the expected
result without any crash.
On which system did you get that failure ?

Thanks,

Hi Wayne,

ParaViewWeb informations can be found here:
http://www.paraview.org/Wiki/ParaViewWeb
There is a demonstration server here: http://paraviewweb.kitware.com

BTW, ParaViewWeb is JavaScript based framework that has several
renderer technologies (JavaScript, Flash, Java applet) and the
JavaScript one do not need any client installation (either flash or
java) and even work on iPhone/iPad.

Re: [Paraview] ANN: Upcoming changes to ParaView Server Manager

[Sebastien Jourdain]

Hi Folks,

The time has gone and we plan to merge the Collaboration branch to
master this Friday (April 8th 2011).
So if anyone has something to say, please do it before Friday or it
will be too late. ;-)

Seb

PS: We will also update the Version number to be 3.11.1.

Re: [Paraview] ANN: Upcoming changes to ParaView Server Manager

[Sebastien Jourdain]

Hi Folks,

We finally merge to master. So next time you build from a fresh
update, don't forget to do a clean build.

Thanks,

Re: [Paraview] Problem loading multiple volumes in ParaviewWeb

[Sebastien Jourdain]

Hi Raj,

The reason why you are not seeing the same settings across your data is
because you need to apply your SetDisplayProperties for each loaded data.
The reason why only the last one is set correctly, it's because ParaView has
a stack of active objects. And since the SetDisplayProperties requires a
"proxy" and a "view", if you do not provide them, ParaView will use the last
one created.

So to solve what you are facing you have to call the following code:

 pv.SetDisplayProperties( {
proxy: data1,
view  : view1,
SelectMapper : 'GPU',
Representation : 'Volume',
LookupTable : lut1,
ColorArrayName : 'ImageFile',
ScalarOpacityFunction : f,
} );

But the best way to go might be to define a method that do that

function setDisplayProperties( data ) {
   pv.SetDisplayProperties( {
proxy: data,
view  : view1,
SelectMapper : 'GPU',
Representation : 'Volume',
LookupTable : lut1,
ColorArrayName : 'ImageFile',
ScalarOpacityFunction : f,
} );
}

and then just call

setDisplayProperties(data1);
setDisplayProperties(data2);

Re: [Paraview] image bufferin ParaviewWeb

Hi Luigi,

the bug you are facing was a bug inside VTK that I fixed maybe just
after 3.10.0.
But you can patch your VTK, as it's a really small fix.

Hi Katsumi,

when you've got questions on ParaView/ParaViewWeb, you should post
them on the Paraview mailing list.
So other could benefit from it.

Thanks

Re: [Paraview] ParaViewWeb Building problem

[Sebastien Jourdain]

Hi Kelly,

Right now you should use ParaView 3.10.1 for ParaViewWeb, but I should
push a fix today for ParaView master.

After my fix, for the ones that wants to use ParaView 3.10.1, you
should used the ParaViewWeb version that come with the tag
"pv-3.10.1". To get that given version from your git repository, just
type: "git checkout pv-3.10.1"

Re: [Paraview] Problem loading multiple volumes in ParaviewWeb

[Sebastien Jourdain]

This is a good news,

I remember that you were asking for JavaScript code samples.
In fact in the Sandbox sample application the whole Python tutorial has been
translated as JavaScript code, so you can see the difference between the
Python and the JavaScript API as well as testing your code.

[Paraview] ParaViewWeb update

[Sebastien Jourdain]

Hi Folks,

I've just push today some fix to the ParaViewWeb repository to support
the latest ParaView git/master.

But for the users of ParaViewWeb that want to use the latest ParaView
release (3.10.1) instead, you should checkout the tag "pv-3.10.1" in
the ParaViewWeb repository.
In order to do that, you can simply type the following command line
inside the ParaViewWeb directory: "git checkout pv-3.10.1 -b
pv-release".

For those who are just starting to here about ParaViewWeb and want to
know more, they can give a look at the Wiki documentation here:
- http://www.paraview.org/Wiki/ParaViewWeb

And if you have questions or issue to report, use the paraview mailing list.

Thanks,

Seb

Re: [Paraview] ParaviewWeb : Adding interactive slice filter to pipeline

[Sebastien Jourdain]

Hi Raj,

You are not getting the propers bounds when you directly access them like
that:

> reader.Bounds

In fact, if you validate each line that you wrote inside the JavaScript
console of your browser, you could have seen that Bounds was not part of the
reader proxy. Moreover, it goes against the idea that Proxy do not have
methods/fields but only properties that can be set/get based on their name.
So eventually, it could have been reader.getBounds(). Although, bounds is
not a property of the reader.
In order to get the right informations, you do need to do call a method on
ParaView:

> var dataInfo = pv.GetDataInformation({proxy:reader});

The returned value is not a proxy, it's just a data structure with all the
data informations of the given proxy. (Fields name, Time, scalar range,
bounds, memory consumption on the server...)

Then you can do :
> sr.setPlaceWidget(dataInfo.Bounds);

I do believe that you  look at the file ParaWebFunctions.js inside the PWApp
to get that close. If not, it could provide you some help on how to handle
some common actions.

Thanks,

Seb

Re: [Paraview] ParaviewWeb : Adding interactive slice filter to pipeline

[Sebastien Jourdain]

Hi Raj,

Another thing. You should do that to set origin and normal.

var plan = sliceFilter.getSliceType();
plan.setOrigin(0,0,0);
plan.setNormal(1,0,0);

in fact the methods SetSliceOrigin/Normal are helper methods on python
objects and not properties. You can notice it because of the capital S in
the set. This must come from the python trace. If it was a property in
python it would have been written:

sliceFilter.SliceNormal = [1,0,0];

Hope this help you to understand how it is working underneath and how to
easily convert Python generated code into similar JavaScript one.

Re: [Paraview] ParaviewWeb : Adding interactive slice filter to pipeline

[Sebastien Jourdain]

Hi Raj,

do you have a server instance where I can interactively interact with your
use case ?
If so, can you send me the url so I can give a try to set the color mapping
correctly.
(You can do it in private and I will post the solution on the mailing list).

Thanks,

Seb

Re: [Paraview] ParaviewWeb : Adding interactive slice filter to pipeline

[Sebastien Jourdain]

Hi Raj,

I managed to show the correct color by executing that:

sliceType.setNormal(0,0,1);
sliceType.setOrigin(view1.getCenterOfRotation());
pv.SetDisplayProperties( {proxy : slice, view  : view1, Representation :
'Surface', ColorArrayName : 'ImageFile'} );

In fact you shouldn't set any normal/origin on the widget, but instead set
them on the plan of the Slice filter.
The reason why you couldn't select the ColorArrayName was because the plane
was outside the bound of your dataset which was producing no output and
therefore no data array.

Hi Raj,

It's true that you will get a better precision with a slider. For that you
can use the JQuery library, it is lighter than Dojo.
Dojo is the one I used in two of our sample application.

Re: [Paraview] ParaviewWeb two sessions, two views, two volume datasets

[Sebastien Jourdain]

Hi Raj,

first of all you only need one session. A session is basically a dedicated
connection to a ParaView server. So by creating 2 session, you were creating
2 server where you could have created 2 views in the same session and setup
a mechanism to keep both camera of the views in synch.
Moreover, as you are using the same session, you can reuse your objects such
as the LUT.
To keep object in synch, you will have to write some piece of code on the
server side that you could call from your javascript client.
I don't have a simple example in mind but you could look at the pwsimple.py
where I had some binding between the widget and the implicit functions that
it represent. Of course the event type won't be the same but the idea is
there.

In fact inside a Python plugin you should define a method like that:

def bindViews(view1, view2):
   # add some python code to bind the two camera together
   # or maybe set the active camera of view1 to be the active
   # camera of view 2.

I know that it does not give you the full answer but at least it give you
some hints.

Re: [Paraview] paraviewweb on windows

[Sebastien Jourdain]

Hi Katsumi,

as I said previously, ParaViewWeb should work on Windows but it's a
non-tested platform. Which means we can't really help you with that.
So if you don't have any skills in building such system on Windows,
you should definitely try to get a Linux or a Mac. That's exactly what
happen with Luca who finally managed to setup a server on Linux.
