So I worked steadily on the making of a cliff with isosurface. This is the
last result:
An alien planet with two suns and a big moon. Time of visit: exactly at
annual seeding time of local vegetation.
To get an idea of the size of the scene, look at the size of the observer in
his balloon.
The whole landscape is only one isosurface. Very slow to render on my old
machine (about 15 hours, especially the foreground).

As always, comments and criticisms ar welcome!!

Nice though f_ridged_mf is a little bit obvious on the foreground, isn't it?
Maybe sharp ridges are unnatural at this scale (should be eroded)


At least hay fever should be impossible with pollen bigger than nostrils ;-)

Thanks Marc!
Yes I agree. In fact the landscape at the base of the cliff is still not
entirely to my liking. I want to experiment further with that part.

LOL! True if these were pollen.... I believe they are seeds, and thus may be
harmless... except if they were carnivorous!

Oh I understood them as seed but put pollen at scale.... :-)

oops, sorry! yes of course. Still, in an alien world, everything is
possible.

It's very nice so far. The landscape looks realistically eroded. A couple of
comments:

The landscape doesn't look as big as the balloon might indicate. Fine detail
would help here - for example, an extra, finer pigment function in the
isosurface (slow!), coating the land in the foreground with vegetation,
maybe some open water? Not sure what would work best.

I think your haze needs to have a higher altitude: the landscape looks as
though it ends suddenly, and there's no horizon gradient effect ... maybe
use two layers if you're happy with the foreground haze.

Good to see my moon formula getting plenty of mileage!

I await the next instalment... :)

I like the theme.  Takes me back to an epiphany I experienced once in my 
early twenties.  I was working as a bartender for CN Railroad on a 
cross-country train from Toronto to Windsor.  As we rattled across the 
late August farm-scape of southwestern Ontario I was watching the weeds 
and other vegetation along the tracks. It was late afternoon with low, 
warm, sunlight hitting the ripened heads of some Queen-Anne's Lace.  At 
that moment the full enormity of seed-time, and all of nature's 
fecundity took possession of me.

Of cousre your alien setting also conjures thoughts of interstellar 
spores and the like, or the incredible variety of life on earth.

One thing, your scene, especially with the alien planet context, seems 
to allude to a notion of contrast between a barren environment and it 
suddenly bursting forth with unexpected seed.  Yet the rich chocolate 
brown of the cliff suggests freshly cloven and fertile soil.

	Can't help thinking of the dragonriders of Pern... Nice picture.
