Both of these work quite nicely for me. Thanks for the quick info!

Re: [Paraview] Please help!! How to force Render() from a reader
Hi Mark,
Here are what I have tried within my custom reader panel (a subclass
of pqAutoGeneratedObjectPanel) so far and working fine for me. But I
may be wrong as Fabian reported the third one didn't for him.
( http://www.paraview.org/pipermail/paraview/2009-October/014074.html )
// 1. If one is happy with only updating the active view
if(this->view()) // may be null if no active view is present
{
this->view()->render();
}
// 2. All relevant views may be rendered this way, where Ps is a
// pqPipelineSource (a subclass of pqProxy) passed to the constructor
// of the reader panel class
this->Ps->renderAllViews();
// 3. All views including irrelevant ones may be rendered by
pqApplicationCore::instance()->render();
// 4. Or there may be another way something like
vtkSMProxyIterator *pIt = vtkSMProxyIterator::New();
pIt->SetModeToOneGroup();
for(pIt->Begin("views"); !pIt->IsAtEnd(); pIt->Next())
{
vtkSMViewProxy::SafeDownCast(pIt->GetProxy())->StillRender();
}
pIt->Delete();

Re: [Paraview] Please help!! How to force Render() from a reader
On a related tangent to the rendering issue: What method is needed to get the 3d view window to refresh. I have a customized reader panel with a few Qt checkboxes. When I select, for example, "Add Labels", the slot sends it to the server manager and it is correctly updated. However, the text labels themselves don't appear in the window until I do something else like resizing the window, clicking something, etc. What method should be I using? /mark This e-mail message and any attachments may contain legally privileged, confidential or proprietary Information, or information otherwise protected by law of EMCON Technologies, its affiliates, or third parties.

Perhaps you are right in that you need a gui (client) part.
(PV experts: correct me if I am wrong)
>

Here is what I have in the gui (client) part for the "pesudo" live
updating of my time-aware reader (I am using a QTimer for periodically
polling a running case in a simple way). It's sort of brutal
implementation though.
If you are intersted in the full version, have a look at
http://openfoamwiki.net/index.php/Contrib_Parallelized_Native_OpenFOAM_Reader_for_ParaView
// only update pipeline information (RequestInformation())
this->Sp->GetProperty("Refresh")->Modified();
this->Sp->UpdatePipelineInformation();
this->Sp->UpdatePropertyInformation(); // explicitly pull the property informa
tion
// get the last timestep
vtkSMDoubleVectorProperty *tsv
= vtkSMDoubleVectorProperty::SafeDownCast(this->Sp->GetProperty("TimestepV
alues"));
if(tsv->GetNumberOfElements() > 0)
{
const double lastStep = tsv->GetElement(tsv->GetNumberOfElements() - 1);
pqApplicationCore *app = pqApplicationCore::instance();
// set animation time to the last timestep
QList scenes
= app->getServerManagerModel()->findItems();
foreach (pqAnimationScene *scene, scenes)
{
scene->setAnimationTime(lastStep);
}
if(this->Rescale->isChecked())
{
// rescale
QList pipes
= app->getServerManagerModel()->findItems(
);
foreach (pqPipelineRepresentation *pipe, pipes)
{
pipe->resetLookupTableScalarRange();
}
app->render();
}
}

Takuya

Meanwhile I think this is because of the client/server structure. Update within the reader forces RequestUpdateExtent and RequestData for the new time value - but it is not dispayed in the time GUI next to the VCR area. A reader is a server part, isn't it? I guess I need also a gui part. Is there a complete code example anywhere?

[Paraview] Please help!! How to force Render() from a reader
Dear Kitware experts and users, :) I'm still fighting with my live data reader and my deadline is approaching :( In my vtkMultiBlockDataSetAlgorithm derived reader I implement RequestInformation() RequestData() and RequestUpdateExtent() and call Modfied() and Update() from a thread. Sofar all works, I trigger RequestUpdateExtent() for a valid time-value not read up to now. This time value is request by RequestData() and I return the new data - there is just no rendering. I have no idea about how to force it. Thank you very much!
