[Paraview] Question about Python and vtk files
Hi, is it possible to save an element (contour, slice, ...) of the pipeline browser in wtk format (.vtm extension) using Python? For example, with CTRL + S we can save an element (contour, ...) in .vtm file format: can we do the same thing using Python? We only found how to save a state file...

Re: [Paraview] ParaView on ARM based compiler (build fails)
Is this ok to call the Qt function with qreal, then copy this qreal
into a double buffer. I do not think this will introduce to much
overhead. Should I simply open a bug report instead ?
Yup that sounds totally fine. I've committed a fix to CVS head.

Re: [Paraview] Stereo Display 3.6.2
My guess is it has to go with compositing. Try setting the Remote rendering threshold to max (or uncheck the checkbox). Does that help?

Re: [Paraview] saving plugin defaults
pqApplication::instance()-settings() with provide you access to a QSettings subclass (pqSettings). You can add arbitrary key/value pairs to it. A plugin can be assured that the correct settings will be loaded and saved every time ParaView is started (unless it crashes of course).

Re: [Paraview] saving plugin defaults
Thanks, works a treat. Just for anyone else interested, it's pqApplicationCore,
and the following example works nicely for my first test.
pqSettings *settings = pqApplicationCore::instance()-settings();
settings-beginGroup(DSMManager);
// servers
settings-beginWriteArray(Servers);
for (int i=0; ithis-UI-dsmServerName-model()-rowCount(); i++) {
settings-setArrayIndex(i);
settings-setValue(server, this-UI-dsmServerName-itemText(i));
}
settings-endArray();
// active server
settings-setValue(Selected, this-UI-dsmServerName-currentIndex());

settings-endGroup();

[Paraview] Plugins for custom apps
Hello, I have a custom (branded) app and a custom PV plugin. I'd prefer to keep the code for these separate, just for clean development, but I want the app to know about the plugin so it can package them together automatically. I can compile both at the same time by putting them each in their own subdirectory, and having a root CMakeLists.txt simply specifying the names of those subdirectories. But, when I list my custom plugin in the app's OPTIONAL_PLUGINS, it doesn't get packaged with the app libraries. (PointSpritePlugin does, though, as I told it to.) Is there some less-naive structure I should be giving my project rather than just two separate subdirectories (and accompanying CMake files) so my app will know about my plugin (and maybe so they can also be built into the same build/bin directory, kind of like when paraview is built)? Also, for clarification, the notes on the wiki for Writing_Custom_Applications says that OPTIONAL_PLUGINS should use name of the plugin specified in the add_paraview_plugin call, but PointSpritePlugin works and it's actually the project() name rather than the add_paraview_plugin() name (which is CSCS_PointSprite_Plugin). Thanks a lot, -Eric ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
Re: [Paraview] How to make movies using trajectory data of granular particles
Could you be more specific about what format your files are in? Many different
file formats use the .xyz extension, and the .dat extension is so generic as to
provide no real information whatsoever. ParaView provides two readers that
read files that use the .xyz extension: XYZ Molecular data files and PLOT3D
files. However, as neither of these files have an associated .dat file, I
don't think either of those is what you want, which is probably ParaView is not
reading the data correctly.

[Paraview] Application using Paraview library in C++
Hi all,
I am attempting to use paraview's library to visualize medical volumes in
an application I am building from scratch. The program is written in C++.
I am having a hard time finding adequate documentation (forums and examples)
that shows how to build an application that uses paraview's library in C++.
I have ran the example program BasicApp.cxx and it works, but it uses a
SphereSource. I am loading dicom images or .vtk images. When I edit the
code for BasicApp.cxx to load .vtk files I get an error after setting the
representation to volume. From reading similar problems on forums, I think
the problem pertains to colormaps and scalars, but I cannot find
documentation on how to fix this in C++. I'm including my code below. I
may be over complicating this, but any help is appreciated.
Thanks for your time!
