Re: [Paraview] Extract Point Data | Nearest Neighbor Location

[Sebastien Jourdain]

You could try sampling the unstructured grid with the polydata. But you
might run into issue if the polydata points end up outside if the
unstructured grid.
You could blow a little bit the unstructured grid by scaling it a bit...

Re: [Paraview] Extract Point Data | Nearest Neighbor Location

[Sebastien Jourdain]

So you are saying that the ExtractSurface on the Unstructured grid won't
produce the same polydata since it will be more refined than your file2? If
that's the case, then maybe just looking for point closer could be the
solution.

Re: [Paraview] Extract Point Data | Nearest Neighbor Location

If they are truly the "same" why don't you forget your file2 and generate a
polydata from the file1 as a file3?

Re: [Paraview] vtk renderer question

[Sebastien Jourdain]

The reason why it is not working is because you removed the container of
the renderer from the DOM.
Therefore, you will have to set its container again... Basically it is
rendering somewhere in a detached DOM element.

You can do that, or simply use CSS to hide that DOM element.

Re: [Paraview] paraviewweb, linked views, mouse handler

[Sebastien Jourdain]

So ParaView 5.5.2 still don't have the correct code base, but
ParaView/master works exactly as expected...

If you look back at our previous email thread, I must have highlighted  to
you what was the change I had to do on the server side, which you can
easily pick since it is just Python code with your current ParaView version.

Re: [Paraview] paraviewweb, linked views, mouse handler

[Sebastien Jourdain]

You need ParaView 5.5.2 or master as I said last time, I fixed some stuff
on the python side to properly register animation on a given view.
Or you may have patched your ParaView. But for sure, you need Python code
along with the pvw change I made.

Re: [Paraview] paraviewweb, linked views, mouse handler

[Sebastien Jourdain]

Hi Tom,

- The mouse handler seems to listen only to one view...

I though the example in https://github.com/Kitware/paraviewweb-examples was
taking care of that. Or maybe I don't understand what you mean here.

- The behavior I observe is that one of the views moves...

That could be possible but are you using the latest ParaView/master?
Normally any registered view should receive a stream of images. With the
fix I've done last time for the multi-view.

- When I make one of the views invisible...

Do you still have a css / size issue when you make it available again? You
need to inspect the DOM to see where that component is present (area of
active).
Then does interacting on that area is not enough to get the images, or
interacting does not work because the "active" area has a size 0x0?

Re: [Paraview] vtk renderer

[Sebastien Jourdain]

Hi Tom,

Glad you figure it out. What I was previously trying to say was that in you
CSS definition you were not providing any constraint on the width and the
behavior of a container was to match the width of what it contains unless
the contains is smaller than the width of the window (block). So the parent
container has no reason to shrink since it always contains a canvas of a
fixed size. Unless you tell that container that it should not be affected
by the size of what is inside.

Re: [Paraview] vtk renderer

[Sebastien Jourdain]

The renderer will ask for its container size when you call resize() on it.
So if that container keep growing due to the setup of your css, the size
propagation won't go to the server as the container will never shrink.

You need to fix the width in some way like you did for the height. You can
use 50vw or use a mix of absolute/relative position in your dom hierarchy.

Re: [Paraview] vtk renderer

[Sebastien Jourdain]

Hi Tom,

That would be a ParaViewWeb question. The issue is related to the css for
your div that contains the renderer.
To allow the renderer to shrink you need to set "overflow: hidden;"
assuming the rest of the size of the div is defined by other constraints.

Re: [Paraview] paraviewweb multiple renderview problem

[Sebastien Jourdain]

Hi Tom,

There might be a bug (sometime it happen ;-). If you can provide a tiny
example app with a cone and cube in two views, I might be able to quickly
look at it and even fix the source of the issue.

1) The active view won't help you in your current setup as it is a
convenient way to ignore the view id. But since you need a clear
distinction, you will have to stick to a given view id to prevent mixup.

2) They are supposed to be unique and we know by nature they are a counter
and -1 represent the "active" one. Normally the type should not matter. But
the server usually send it as a string.

3) Normally the mouse handler hold that viewId as well. But if not provided
(-1), it will affect the active view.

HTH,

Seb

Re: [Paraview] ParaViewWeb and multiple windows

[Sebastien Jourdain]

You should set the viewId to the VtkRenderer based on which view from the
server you want to be bound to.
To retrieve the view Id on the server side, just call on the python side.

view.GetGlobalDAsString()

I may have small typo for the method name, but in either case the number
you want is the "GlobalID".

HTH,

Seb

Re: [Paraview] AppendAttributes issue

[Sebastien Jourdain]

This has to do with the origin of our vtkImageData which is not using the
same as your elevation data.

Yes threading is bad. I didn't noticed that you were creating threads in

You need to register the following protocol
https://github.com/Kitware/visualizer/blob/master/server/pvw-visualizer.py#L196

Then make sure you call:

Re: [Paraview] VRML animation

[Sebastien Jourdain]

Putting back the mailing list as other could provide an actual answer to
your "immersive question".

ParaView can do immersive animation but that would be managed within
ParaView. So I'm still not sure to understand what you are trying to do.
But maybe other on the mailing list may do...

Re: [Paraview] VRML animation

[Sebastien Jourdain]

May I ask why VRML? Are you trying to do a time animation of
geometry+data/color on the web?
What I'm trying to say is that often by narrowing the question you get a
perfect answer for it but not a good one for truly solving your problem.
So what are you trying to do/solve?

Thanks,

Seb

Re: [Paraview] immediate update

[Sebastien Jourdain]

In the latest version of ParaViewWeb, I've added the Native implementation
of it while the other one was React only.
Divvy is the application that use the native one.

https://github.com/Kitware/divvy/blob/master/Sources/scatterPlotManager.js#L134-L140

For the client, we initialize it like that:
https://github.com/Kitware/divvy/blob/master/Sources/client.js#L27-L29

HTH,

Re: [Paraview] immediate update

[Sebastien Jourdain]

ViewPortImageDelivery require the JS side to request a render
while VtkImageDelivery allow the server to push the image without the
client requesting it (self.getApplication().InvokeEvent('UpdateEvent')).

VtkImageDelivery is used inside those components:
https://github.com/Kitware/paraviewweb/tree/master/src/React/Renderers/VtkRenderer
https://github.com/Kitware/paraviewweb/tree/master/src/NativeUI/Renderers/VtkRenderer

Which renderer do you use and how do you set it up?

Re: [Paraview] how to make a new protocol

[Sebastien Jourdain]

Hi Tom,

The array list should only contain the names that belong to that directory:
https://github.com/Kitware/paraviewweb/tree/master/src/IO/WebSocket/ParaViewWebClient

Then your custom protocol should looks like:
https://github.com/Kitware/paraviewweb/blob/master/src/IO/WebSocket/ParaViewWebClient/ProxyManager.js

Except that you will need to nest it inside an object like:

{
  CustomProtocol1: [...content of the previous example...],
  CustomProtocol2: [...content of the previous example...],
}

Then to use it you will do:

client.CustomProtocol1.availableSources().then(...

You can find a live example of its usage here:
https://github.com/Kitware/divvy/blob/master/Sources/client.js#L27-L65

HTH,

Seb

LightViz will be a good example as it defines a custom set of protocols
instead of using only the default ones like in Visualizer.

 Thank you that's very helpful. Where will I find how to define the

 like this:

 from wslink import register as exportRPC
 from wslink.websocket import LinkProtocol

 class myProtocol(LinkProtocol):
 def __init__(self):
 super(myProtocol, self).__init__()

 @exportRPC("myprotocol.testButton")
 def testButton(self, nothing):

 Pvpython isn't happy with this, but I'm not sure where to look for the
 right way to do it.

 Thank you,

Re: [Paraview] Using ParaviewWeb examples

[Sebastien Jourdain]

Hi Tom,

So everything is up, so you can checkout the website.

Regarding your loader, I think it is good. You can look the ones we use
here:
https://github.com/Kitware/paraviewweb/tree/master/config

And for the dependency, we let the user to add every dependency required
instead of forcing a specific version in our pvw dependency list. That way
they can update or pick version at their own discretion.
Especially if a dependency is missing the error message is pretty explicit
regarding which one needs to be added.

Re: [Paraview] Using ParaviewWeb examples

[Sebastien Jourdain]

Hi Tom,

I've just updated ParaViewWeb documentation (setup) to reflect the latest
tools that we use.
Also I've updated the examples to use absolute path so you would not need
to figure out those relative path resolution.

Travis is currently building the new version along with an updated website
which usually take around 25 minutes to complete.

Re: [Paraview] Using ParaviewWeb examples

[Sebastien Jourdain]

Hi Tom,

Try to stay with the latest webpack. The setup doc was initially describing
the ParaViewWeb config itself.
But since we've updated the build process of ParaViewWeb, you could look at
the actual configuration of ParaViewWeb itself. That will give you the
proper set of files.

https://github.com/Kitware/paraviewweb/blob/master/webpack.config.js
https://github.com/Kitware/paraviewweb/blob/master/prettier.config.js
https://github.com/Kitware/paraviewweb/blob/master/package.json
https://github.com/Kitware/paraviewweb/blob/master/.eslintrc.js
https://github.com/Kitware/paraviewweb/blob/master/.babelrc

Hope that helps until we fix and update the documentation,

Seb

Re: [Paraview] Using ParaviewWeb examples

[Sebastien Jourdain]

Hi Tom,

The documentation was written when we were still using Webpack 1 and
unfortunately it is outdated.
I'll try to update it so it will be easier to follow for users that don't
know any of those web tools.

For normalize, you can find some information directly on their web site
https://necolas.github.io/normalize.css/

 Hi Tom,
 The ParaviewWeb examples always live in a sub-directory of the
 component they illustrate - so here, this is the Composite example, so '..'
 just refers to 'Composite'.
 If you look in the left menu, you can see that 'Composite' is grouped
 into ' Component/Native'. That's the directory it's in.  
 '../../BackgroundColor'
 is a sibling directory to 'Composite', so it will also be in '
 Component/Native'

 Generally you can follow the '..' out from the example sub-directory
 and figure out where you are.

 Hope that helps,
 Aron
