[Paraview] Data structure for 'table to structured grid' filter

[fenglei qi]

Dear all,

I met a problem when I converted table data to structured grid. The data
is arranged as attached test.csv file. I set up Whole extent as ((0,2),
(0,2), (0,1)). But the grid system does not look right. See below. I think
the problem is the data ordering problem that are usually talked about in
previous threads. Can anyone give a example of how to use this filter or
give me some information on how to do it correctly. Thanks for all your
considering.

Hi,

I think the issue is that your ordering is wrong. VTK/ParaView assumes that
you iterate over x the fastest, then y, and z is iterated over the slowest.

For the table to structured grid filter, if you set the whole extent to [0,
2, 0, 1, 0, 2] and the X Column to y, Y Column to z and Z Column to x then
at least the connectivity looks correct. If this output has the wrong
orientation you can either change the ordering of the CXV file or use the
transform filter to rotate it around.

Hi Andy,

It works in your way. Can you provide more information on how to make a
correct ordering of points. I don't understand how the connectivity is
built in Paraview. Any sources for me to refer to? Thank you.
