Well, here is a new visit to a landscape I submitted in 2004 to the Desert 
topic of the IRTC. The landscape is composed of two isosurfaces (rocks and 
dunes) and a height_field in the distance. I reworked a little bit the 
textures used there, but not extensively. I added a media atmosphere and an 
area_light sun, tweaked the radiosity settings, and I exchanged the original 
cacti with Micha Reiser's blob bushes. Finally, I added the human touch 
(Chappe's semaphore, signpost, human and pet, old foundation) and changed 
the aspect ratio.

This is not Gurghusht (sorry Yadgar  :-)  ). This is Terra Incognita 
Australis (*not* Australia!) discovered in 1602 by Johannes Isidorusz. 
Kabeljauw (1581-1612) an early explorer of the VOC, and only rediscovered 
once by the adventurer Markus von Kopelstock in 1923... or so my imagination 
reconstructed history... ;-)

Rendertime has been extreme. I think that, on and off, the image took about 
80 hours or some more to be finished on a dual core machine using version 
3.7.

Great scene!  landscaping is superb--very believable shapes for the 
rocks and dunes, and the textures are excellent for them.  I think there 
ought to be a little green lizard on the one of the close rocks though.

Thanks Kirk!

Yes! I wanted to put a lizard there and then forgot all about it :-(   I 
shall add it soon though. Thanks for reminding me.

   These dunes look very nice, tough the ripples seem too perfectly
aligned... anyhow a very good attemp for such a difficult subject.

   The rocks are great, very geological-looking in shape. Congrats!

Thanks indeed, Jaime. I am not too happy about the sand ripples either. The 
textures needs more work, especially with the alignment. Maybe a bit more 
controlled turbulence will do the job. Something still on the ToDo list.

The rocks isosurface was one of the first compositions which led me later to 
my Geomorph macro.
