[Paraview] Connecting points with line

[Andy Bauer]

Hi Patrik,

Please keep the discussion on the mailing list so that everyone can
participate.

As for connecting points via a line cell, I don't think there's any filter
to do that since it would have to make an assumption about which points
should be connected by a line cell. To use my recommendation, after the
Table To Points filter, select the Programmable Filter, enter that text
into the Script entry widget and hit apply. What it does is connect the
first point to the second point, the second point to the third point, ...,
and finally the second to last point to the last point. If you have some
different way you want to connect the points you can change the script
yourself. Note though that this filter may not work as desired in parallel.

Andy
