You could of course always "cheat". Do some computations to figure out
the distance from the camera where grass should be, and if far enough
away just use texturing instead of objects. Not tried it. Might work.
get rid of a couple hundred thousand cones or so I'd guess.

Hmm. You could also try multiple height fields. Maybe three. slightly
pitched about with a rotate so that the grass can overlap.... hmm. If
you precompute a few cycles of grass into height fields you could even
do some "wind through grass" effects by sliding and tilting the hf's.
Tricky. but maybe.....

In the end, it doesn't matter if it structurely looks like a blade of
grass, only that it looks like a blade of grass enough that no one
notices otherwise. :)
