Hey ! you signed to be the 1st SpaceShipOne space tourist before Richard
Branson? (who can believe he did not want to be the 1st?)
Your Geo renders are more and more incredible!

Thanks!
Another render can be found on:

Interesting, but that does not tell you much how it looks like from 20km
height... ;-)

Stunning... and obviously, the 3-arcsecond DEMs for the USA don't
contain those ugly data gaps I noticed with the Eurasia files (for
example the Kabul area) - or do they in fact exist even in the DEMs you
used, and you just somehow interpolated the missing data?

Christoph,
your system, while arguably still not perfect (the LOD could be worked on),
is simply amazing. The geometry rendering is one thing, but your
atmosphere and lighting are incredible as well. The whole thing has some
insane educational value -- at least your recent earth images sure sparkle
*my* imagination far better than any map I saw in school. How long are the
current rendering times?

What's the problem about that? Of course the data resolution is limited
but that's something i can hardly influence.

Thanks, render time for the first one was quite slow (because of the
smoke) - the second one was much better optimized and rendered in 4-5
hours (2400x1800).

I was referring to you planet rendering system in general; the seams are
clearly visible in a few pictures, although the St. Helens image is very
good. Of course it also depends on the field of view. From your pages I
understood your techinque already uses intepolated transition zones between
hi and lo detail areas -- is it just that some images don't utilize this
feature (for example, earth_kilimanjaro1.jpg)?
How much pre-processing these images require? Can you have the global
height/texture data 'as is' on the disc, and have your modded pov-ray
selecting which parts to actually read into memory?

The kilimanjaro pictures are meant to illustrate that there are
different data sets combined so the visible transit is intentional. I
doubt there are visible seams in any of the other images at the size
they are on the website.

The images are just prepared in the required size and then used in
POV-Ray. I don't understand why you would need to modify POV-Ray for that.

Could we have the URL link of the kilimanjaro render.
Thanks
