How to use vtk sequence of files to animate them?

Andrew Somorjai — 2013-05-22T22:16:44

Hello,

Thus far this is what I've accomplished with Paraview but I cannot seem to get my animation to run properly as I will explain at the end.

1. I took a sequence of 30 vtk format files made by Athena (MHD numerical software) and imported all of them into paraview.
2. I added every single one of them to the animation view.
3. I changed each vtk grid to only run for 1 second and each vtk is a frame with 30 seconds and 30 frames total.
    Basically frame 1 is before frame 2 and so on and none of them overlap in time.
4. I noticed that toggling a  "eye" in the pipeline browser turns off specific vtk grids in the 3d viewer and for some reason this is where things don't work.

If I select all of the "eyes" and turn them on only the last one turned on causes the selected 3d vtk grid to appear. I can only render that image when I
try to animate all the 30 frames using file->save animation->avi. I expect that at each frame every second a different grid would show and get animated.

Please feel free to ask

Help with Glyph Colors

Scott, W Alan — 2013-05-22T22:06:28

I have a map on which I've placed numerous glyphs (circles at earthquake locations).  I'd like to change the colors of the circles individually, and maybe the continent outlines as well. I also want to add some more data, maybe triangles, with a different color. I haven't figured out how to change the glyph color without changing the color of everything else.

Thanks,

Alan

Scalar components and Python Calculator

Pettey . Lucas — 2013-05-22T21:55:20

Hello,

I am trying to use the Python Calculator on 2 different Scalar components in the same data file.

I have written the real and imaginary parts of a Fortran complex data type to a single ".raw" binary file. ParaView correctly opens this file when I tell it that there are 2 scalar components.

I can use the Calculator to perform calculations on the "X" and "Y" components (the real gets imported by default as ImageData_X and the imaginary as ImageData_Y). An expression in the Calculator filter such as:

sqrt(ImageData_X^2 + ImageData_Y^2)

works fine. The Python Calculator, however, generates an error that ImageData_X and ImageData_Y are not defined.

Both filters are set to Point Data.

Any suggestions?

Thanks
Lucas

Anton,

The bug was when using system OGGTHEORA support. I've a fix that
should go into master after the next gatekeeper review.

We will have a detailed summary for the new features and enhancements
in this release soon. In the mean time, a complete list of features
implemented and bugs fixed in this release can be found on the bug

I have always done a 'git pull' on VTKData, VTKLargeData, and
ParaViewData before I run my dashboard scripts.

The last commits in VTKData and VTKLargeData emptied out these directories.

Should I check out the versions just before the external data change and
stop updating them?

Re: Adapt to VTK ExternalData

Utkarsh Ayachit — 2013-05-22T12:51:21

ParaView is not using VTK-master yet. It will be switched to use
VTK-master only after the 4.0 release. We will be updating the testing
then.

VTK has switched from using VTKData to ExternalData.

VTKData is now almost empty and Paraview tests are failing on my

There used to be an infoviz plugin for paraview (I think). Is this what’s left of it or a different integration you’ve done separately?

Hi, Seb

It's very kind of you to share the code, which will make me understand Paraview much better.

There is little information about cusomizing Paraview, so a workable example will be very useful.

Thanks again.

Re: Correct ActiveMQ server version or config with ParaviewWeb SuperBuild

Sebastien Jourdain — 2013-05-21T14:02:02

The current version of the session manager based on Jetty is just a
starting point and depending on the deployment that you expect, you may
build your own.
In fact, there is still some work to be done if we want to make it bullet
proof. Although, using apache as a proxy and jetty as job launcher seems to
be pretty reliable.

But if you like the light weight and ease of deployment of the current
JettySessionManager, you may find a system based on Node.js as easy.
In fact, to provide a larger set of front-end technologies, we were
thinking to use Node.js for that as it seems to have built-in websocket and
http proxy/forwarding capabilities.

If you want to give a try, you can read
https://blog.nodejitsu.com/http-proxy-intro, and if you have something that
you are willing to share we can extend our "SessionManager" code base.

Thanks,

Seb

Fetching selection from SpreadSheet

Stephan Rogge — 2013-05-21T10:44:25

Hello,

I use the SpreadSheetView to visualize a vtkTable. Now I want to fetch the
data of the row which is currently selected.
Right now I can connect to a selection event but have no idea to obtain the
slected data row.

pqSpreadSheetView *ssv = qobject_cast<pqSpreadSheetView*>(view);
QWidget *widget = ssv->getWidget();
QObject::connect(
     ssv->getViewModel(), SIGNAL(selectionChanged(const QItemSelection&)), 
      this, SLOT(spreadSheetSelectionChanged(const QItemSelection&)));

When my slot is called, QItemSelection is empty.

Antti Vanne — 2013-05-21T10:14:42

Thanks Sebastien,

the nightly build works nicely. We're using Jetty as a frontend. Where
would it be easiest to set Jetty's properties? When a larger model is
transferred to client in geometry form, the default max message size is met
pretty soon.

Re: Programmatic access to Probe Location point

Andy Bauer — 2013-05-21T01:48:47

Hi,

It's a sub-proxy that is used to define the probe location. The name of
that is FixedRadiusPointSource. You can find that in filters.xml (partly
shown below). The proxy definition of FixedRadiusPointSource is in
utilities.xml (also partly shown below).

Hope this points you in the proper direction.

Programmatic access to Probe Location point

Reuter, Michael A. — 2013-05-20T20:00:33

Hi,

I'm trying to programmatically (C++) access the point coordinates displayed by the property panel widget after the p key is pressed. I have a pqPipelineSource pointer from when I created the Probe Location filter, but I can't seem to find any properties (tried Point, Center, WorldPosition) on the proxy that work. I also tried accessing those properties via the source proxy, but no luck either. If the proxy has the information, what is the correct property name? If not, where do I need to be looking?

Thanks,
