Some reasons why I'd like this beeing raised to priority 1:

1. works better than existing pm3d methods which assume ordered data,
   so the depth method is a method which can be turned on by default
   while the other methods will produce junk for unordered data and
   also especially for data generated by parametric plots.

2. another postponement will add more work to include it again and again
   into current gnuplot versions, therefore makes it more likely that
   the patch will finally die.

A personal note: actually the absence of this patch in gnuplot is the main
reason why I don't upgrade gnuplot!

Best wishes,

It seems my automated scheme to elicit comments is working :-)

OK. This one can go to cvs without further change.
The April version still applies with no error.

As discussed previously, I would still like the option
to sort these pm3d rectangles jointly with labels and arrows.
But that would involve a different code path altogether, and
adding your version now does not preclude offering a variant
triggered by 'set hidden3d' at some later date.

you mean 9, the highest?

There is my comment from 2005-06-21 how to put (at least) its cosmetic 
changes into cvs. Have you commited them at least? It looks like you have 
not pushed this patch too strongly.

Further, is there a demo?

Petr:

I've modified the original patchset to use your suggested
'set pm3d de$pthorder'.  The code itself is ready for cvs.

The interlocking tori in the last plot of 'surface2.dem'
do nicely as a demo.

But it still needs a section for the docs.
