Finished this render today: 3 days, 21 hours.
I think i will not work much more on this particular setup, the sky surely
could use some improvements, but it's more interesting to try some
different shapes.
I followed R. Suzuki's suggestion to try using 'evaluate' to speed up the
render. Although i don't have a direct comparison, i think it is
significantly faster. Radiosity settings are slightly higher quality than
before.
The statistics show a number of DNoise calls being a new personal record
for me: nearly 257 billions, the previous maximum was 220 billions ;-)
What's probably more interesting is the histogram i generated for the
render, it can be found on:
http://www.schunter.etc.tu-bs.de/~chris/files/lnd_hist.png
It also shows that the horizon is not slower than the rest of the scene.

Much better! Now the foreground looks great too, and as always the sky is
outstanding. Only the most distant clouds are a bit flat.
What about adding some dry plant...

That terrain is fascinating. An exquisite render, Christoph! I'll try to
remember the evaluate-trick. I'm downloading beta7 right now. I'm going to
do something with radiosity I think... :)

Yes, they are simply a flat texture, should be improved.

Hmm, what kind of plants? Maybe some grass... I'm a bit afraid of the
memory requirements, radiosity already takes 220 Mb.

Thanks!

I will do some more experiments with the parameters, there's always the
danger of holes occurring, but i had luck this time...

Try inverting that image (ie. making it negative) with an image editing
program. Looks almost natural.

Yes, indeed.
The reason is probably that the slowest regions are those where most
radiosity samples are not taken from the sky but from the isosurface
itself.

Monstrous... what computer do you use?!? Thunderbird 1.4 GHz with 2 gigs of
RAM or even greater?

512 Mb RAM are perfectly sufficient, it took just above 200 Mb and only
for radiosity, without only 300k. Processor is an Athlon 1 GHz, but
that's just a matter of patience... ;-)
