<div class="moz-cite-prefix">Thanks, now I can pass the information
from the filter to the source using:<br>
- The CONTINUE_EXECUTING in the RequestData() in the filter<br>
- In the RequestUpdateExtent() of the filter I have<br>
<br>
vtkInformation *inInfo =
inputVector[0]->GetInformationObject(0);<br>
double val[3] ...<br>
inInfo->Set(vtkPXDMFDocumentBaseStructure::UPDATE_FIXED_DIMENSIONS(),
val, 3);<br>
request->AppendUnique(vtkExecutive::KEYS_TO_COPY(),
vtkPXDMFDocumentBaseStructure::UPDATE_FIXED_DIMENSIONS());<br>
<br>
-The information key is recovered in the REQUEST_UPDATE_EXTENT()
request in the source (when I change something in the source).<br>
<br>
When I create the filter, the filter gets executed the correct
number of times, BUT the source is never executed (the
ProcessRequest member function in the source is never called).<br>
<br>
What key or option I have to enable to re execute a source for a
downstream filter?? <br>
Or a way to tell the source is out-of-date?<br>

<p class="MsoNormal">Hello,<br>
<br>
I have a source (home made reader) that is capable of generate
data depending on some options.<br>
I like to control theses options using a filter way down in
the pipeline. This means that I would like to send a
vtkinformation upstream in the pipeline and also iterate for
different values of this options. Something like the
TemporalStatistics filter but not over time.<br>
<br>
Till now, I tried to use the
vtkStreamingDemandDrivenPipeline::CONTINUE_EXECUTING
information (in the filter) to iterate over the data. My
filter is re-executed but my source get executed only once.<br>
<br>
Also tried to set a vtkInformationDoubleVectorKey to the
inputVector in the RequestUpdateExtent() of my filter with
some data but this information is never passed upstream.<br>
<br>
Is this possible??? or we can do this only for time.<br>
<br>
Thanks for all<br>
Felipe<br>
