[vtkusers] VTI time series and piece extend

[Biddiscombe, John A.]

I've seen another report of a similar bug.

What must be happening is that when the UPDATE_TIME is changed inside the pipeline, for whatever reason, RequestInformation is not changing the WholeExtent of the output data and so you are not seeing the imagedata change size.

You should file a bug report and attach your observations and my comment.

If you have a dataset that can be shared which I can have a copy of, please contact me off list and I'll try to look at it.

Subject: [vtkusers] VTI time series and piece extend

Hi,

I use vtkXMLImageDataWriter with ZLIB and appended mode to produce a
time series of vti files (lbm_0.vti, lbm_30.vti ...) which
change their domain size in time. For example, lbm_0.vti has <Piece
Extent="0 60 0 60 0 61">  and lbm_1020.vti has <Piece Extent="0 86 0
86 0 61">. When I load the series into the Paraview, the domain does
not enlarge and stays at its initial size. When I load lbm_1020.vti
separately, it has the correct domain size. Do you have any idea why is
that and how to make that work?

And a second question. How do I write a pvd file using activiz vtk wrapper?

Thanks in advance
Oldrich
