Very interesting!... I believe you'll probably have to struture your
mesh yourself, like Hans said...

Do you have a bunch of data you are fitting to a surface, or is it a
function that you want to plot?...

If it's a function, just make a small program that draws the mesh...
You can even make a triangular mesh, it would be closer to your
"problem language", and is even easier to do then a square mesh.

If it's a bunch of data you are fitting to a surface, you'll have to
find a small program to do the fit, I'm not sure if gnuplot alone
would be flexible enough for you...
