Dear Utkarsh,
thank you very much for your fast reply and the provided example.
I compiled PV4.2RC2 from source and just tried to compile your example.
Nevertheless I receive a compilation error complaining that the file
vtkSMParaViewPipelineControllerWithRendering.h
cannot be found.
Where is this file supposed to be residing ?
Thank you.
Best regards,
Florian

Attached is an example based on ParaView 4.2-RC1. As it shows, you
cannot directly use VTK objects to create visualization pipelines in
ParaView. While this can surely be done with 4.1 or earlier, I'd
suggest basing off 4.2, if possible since it simplified a lot of this
initialization.

I would like to automatically add a glyph filter and render the correctly
scaled spheres after the user has opened a file in my custom dock widget.
I created a DockWidget using the example in /examples/Plugins/DockWidget.
When pressing a button a specific file is being opened for the user
by the
following calls:
void on_button_clicked()
{
QString xdmfFile = "C:\\..\\unknown_case.xdmf";
QStringList visuFiles;
visuFiles.append(xdmfFile);
pqPipelineSource* pqPlinesource =
pqLoadDataReaction::loadData(visuFiles);
pqPlinesource->updatePipeline();
// TODO:
// add spherical glyph for loaded polyData
// scale spherical glyphs by a scalar attribute/property
// render glyphs
}
I would like to include that the code automatically adds spherical glyphs
and renders them for the data just loaded.
I tried the following code but I am not sure if it works
vtkSMProxy *myProxy = pqPlinesource->getProxy();
vtkObjectBase *myObject = myProxy->GetClientSideObject();
vtkAlgorithm *myvtkAlgo = vtkAlgorithm::SafeDownCast(myObject);
vtkGlyph3D *myspheres = vtkGlyph3D::New();
myspheres->SetSourceConnection(myvtkAlgo->GetOutputPort());
In case this is supposed to work, how can I now update the pipeline and
render the spheres using C++ PV core functionality ? (The user should
also
see the result in the pipeline browser dock of the GUI).
In case my approach is totally wrong, what would be the right way of
handling this situation ?
Thank you.
Best regards,
Florian
