Here's an example of a vtk file for a vtkImageData. You should replace your point_data with the stuff in cell_data and below.<br><br># vtk DataFile Version 3.0<br>vtk output<br>ASCII<br>DATASET STRUCTURED_POINTS<br>DIMENSIONS 6 6 6<br>

Thanks Andy,<br>
<br>
I do have values in the cell centers, but when I change
representation to the Surface (or Surface with Edges) <br>
and then plot two clips in different dimensions getting what is
showed on the picture. <br>
I just want my data not to be shifted against each other when
plotting these clips. <br>
<br>
How should then data be written (rectilinear structured grid with
values assigned to the cell centers) to be properly visualized?<br>

you're trying to represent and how you're hoping to do it. The
grid you sent only has point data while the image you sent looked
like cell data so something is inconsistent. <br>
<br>
The only thing I can think is that maybe your writer is getting
confused with the dimensions. For VTK structured grids like
vtkRectilinearGrid, the dimensions are the number of points in
each direction.<br>

Please find attached my data.<br>
I suspect there might be something wrong with my way of
writing VTK files. Can you confirm this file is ok or
not?<br>
It is desirable to avoid my own filter since I'm not
familiar with python and ParaView filters. <br>

If this is really your data though and you want to
change it then you'll either have to write your own
filter or use the python programmable filter to make
the adjustment.<br>

I'm visualizing structured rectilinear grid and
noticed there is some inconsistency with shown
values. Attached you will see two clips taken from
one dataset.<br>
I want them to match however they do not. Can I do
it somehow?<span><font color="#888888"><br>
