Hi,
this looks very promising!!
Since you ask for feature requests:
1) 3d support. This is of course a very big request, but it would also be
useful for many people.
2) About graphing, it would be nice to be able to do contour polots and
density plots. I know I asked for contour plots some time ago, and there
were some examples, but I don't think there was ever some built in support
for it. Maybe that can be done "easy" with help of lua? I guess there exist
good algorithms.
3) (small) The possibility to have arrows in coordinate axes. I have not
had the possibility to test the new features today, and maybe this is
already built in (drawarrow?), but I mention it since I did not see it in
the pdf.
Again, it is very nice that you work on extending MetaPost/MetaFun further!!
/Mikael
