Greetings Spider Man,
Pretty cool looking stuff dude. I haven't looked at the source yet but
I am curious as to wether you are storing your data inside of arrays.
I understand this can help a lot where memory effeciency is an issue.
Also concerning your problems with the stack overhead. I was reading
through the section in the docs concerning adc bail out, max trace levels,
and max intersections. In each area of discussion there was mention of
the stacks use in the program and may give you some insight as to how
you might change these global settings or program your code around their
limitations (or process attributes depending on your point of view).
Cheers,

Thanks :-)

Hmm, I store the actual data in arrays, yes.
but the problem is when writing out data.... :-/
> I understand this can help a lot where memory effeciency is an issue.
yes, since it would allocate all the memory at once and don't change it in
between, yes.

I'll look into it, but I don't think they will solve this problem, the problem
isn't when handling the data, but when writing to a file, and I don't know why.

The same :-)

For little ol' me? Oh thankyou Spider!
Okay, I'm over it. That tree... what happened to it?! The leaves are
lost in a grean and gray murkyness. And your poor water got baffled by
all those tiny squares as well.
You may have stumbled upon something good though, no "jaggies" could be
found in all that black and white "pixelation" of both the water AND the
land too.
You really shouldn't have re-rendered at the cost of such a massive
parse. And heck, I thought you had more RAM than that (128 at least),
64MB is what I'm working with too.
What a parse to render ratio. Wow.

Well, I did as adviced and lowered the fog_alt, but in the test renders (12
boxes, no trees) It turned out to thin so I had to decrease the distance... that
is what happened to it.. :-/

Yeah... It really was a hell to render, I'd guess(I was by the Tv :-)

Now here is something you'd have to explain more. I don't understand what you
mean.

hehe, I had never done this before, so I thought, Whatta heck and did. and once
it had passed an hour, I thought I had done so much already, so I could let it
finish ...

Yeah, I had 96 a while ago.... bbut I had to give the 32 back ... :-/

yea... hehe. I think you understand why I'm pretty fed up with the fwrite
crashes .-)

I have little tolerance for parse. Something go wrong only by render
time is the most aggravating. Hey, thought here, parse optimizations:
most spurious stuff parsed first, least last ;)
Didn't mean to confuse about the pixelization comment. I should have
added the word "illusion" and a smilie :)
From what I could see, if jaggies were present or not, I would not have
noticed much judging by all the sharp contrasting small scale blacks and
whites in there (land as well as water part).

I soooo much agree with you. therefore, it's even more frustrating when
it crashes..

Well, that ain't easy... hmm, create the output boxes/mesh first, then
the height-data?? naaa...
Actually, all the functions have almost the same parse-time. the log is
a bit slower than the lin...

oh.. ;-)
I'm doing a new render. it has worked for over 8 hours now. I just don't
seem to end rendering...

Sounds like you need another PC. As they used to say about
clothes in the old days (before I was born), One on, one in the
wash and one spare.
You need a PC to be working on, a PC to be doing the serious
stuff (number crunching), and one to do other bits and pieces on
or use it as a spare.

Whee. Someone who actually wants my macros :-)
Ok, you can find it in povray.text.scene-files with the subject "World macro",
its a rather recent post(5 days ago)
or you can mail me and I'll send you a copy.
