[Paraview] Live Annotation

[Thierry Dubuis]

Hello all,

I'm also interesting to know what is the best way to automatically see 
the time step on the Paraview main window with an XML unstructured grid 
(.vtu).
If I understand your previous emails I must
- in the reader of XML unstructured grid add 
vtkStreamingDemandDrivenPipeline::TIME_STEPS()
- in the readers.xml of th server add the 5 line in the XML unstructured 
grid reader bloc.

Is it correct ?
Or is there better way for this XML file ?

Best regards

Thierry Dubuis
