When I create a field of grass with 50.000 objects or up my computer runs
out of memory! I use a PIII-600 with 256Mb ram! That should be enough,
shouldn't it?

Should be more than enough - I used to regulary use a million or two objects
in experiments on my old 300 mhz P2 with 128 mb of ram

Looks impressive, but the shadows are a bit harsh in places. If you put
in a good looking sky and filled in the shadows a bit with some
radiosity, this could be an awesome pic...

Are you talking about the trace() modification? I would be real greatful if
you could post the changes that are necessary to the code.
Thanks,

Wow Mick... I haven't even tried that many yet.... I guess the grass isn't so
fast when so many are used :) I wonder if making one smaller square of grass
and then copying it would save memory? You'd have to make sure nobody could
see the repetitions.

I'm sorry, I wasn't very clear in my message: does anybody know what I'm
doing wrong? When I try to render a pic with 50.000 or more blades of grass
I get a mesagge that says POVray is reclaiming memory. I use 256 MB of
memory, so that should be enough.
I hope someone can help me!

That's the usual technique but you'd loose the advantage of eval_pigment. I
don't think youd save much memory either. As most of the parsing time was
spent on creating bounding slabs, I guess that manual bounding is the way to
go when I work out how to do it!

When do you get that message, normally you only get that when you stop the
rendering.
I can't off hand think why you are running out of memory - when I first
stared using Povray I had a 486 and regularly went up to 100,000 objects
with no apparent problems other than a loss of patience!

Also add a few dozen area lights (using fade_distance, of course).
