[Paraview] SEG-Y seismic data loading

[Lester Anderson]

Yes indeed David, I am sure it would make an interesting challenge for a
coding exercise. Of course with the SEG-Y format, it would be easier (if
that is the right term) to work on a 2D import first rather than jump into
loading 3D cubes!

I know that with the free GMT software it is possible to read the SEG-Y
data (at least 2D) so I am wondering if there is a potential pathway via
that code? The issues are not simple to overcome, as you need to be able to
extract the positional (navigation) data (and understand the projection
used), and then convert it to a visual format. It would be great if there
was a way of dealing with this import using Python!

Something to definitely think about for a future update.
