Weird... looks like proto-Incan ruins somewhere on the windswept
Bolivian Altiplano at almost 5000 metres above sea level, given the
ultra-deep blue sky!
Or is it a scrapyard for 1970s sci-fi greebled spaceships?

maybe the picture is gamma-corrected for gamma 4.84 displays

The object is completely automatic generated with several medical programs for
MRT and CT data.
It also looks to me like its some ruins in the desert. Cars and people should
share this look. (maybe an India style or something..)

you should always use assumed_gamma 1 so that the scene renders accurately

Yes, but I realy love extreme deep blue sky's and high contrast images.
It's the same way I would make photographic images.
Combine a deep blue sky with an ultra_whide_angel camera - it looks always great
:)

Hello,
Are those programs free?
Thanks,

I doubt it. Most medical programms are specialised applications, only sold to
medical facilities, and usualy cost several $1000.
Another limit: they frequently rely on some input device costing near the
millions mark...

At the moment I'm working as a CGI-supervisor for a film documentary company.
In the last Project, I've worked a lot with scientists and there programs. One
of it was "Matlab" its not free. Another is designed for being directly
connected to a "MRT". It works without the machine, but I think, you cant by it
in a normal way.

Octave is a free 'clone' of it. But you still need the script files
because Matlab is just a big mathematical front end/interpreter. And I
wasn't able yet to install it in such a way that my scripts work. :(

The data from such machines is stored in DICOM format. There are several
free DICOM readers and even source. And the document format is open so
you can always write your own.
Yet the biggest problem is getting data because of privacy issues.
