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
<meta name="qrichtext" content="1">
<meta http-equiv="Content-Type" content="text/html;
charset=ISO-8859-1">
<style type="text/css">
p, li { white-space: pre-wrap; }
</style> 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>
