I made some renderings of planet earth; color & topography.
Medium-resolution images at:
http://www.cip.physik.uni-muenchen.de/~wwieser/render/img/earth/
I'll make some high-res images but first would like to get some
comments.
Regards,
Wolfgang

I want the full-planet DEM data and whatever you used to make it
into the actual bumpy earth. ^_^

I hope your inbox is large enough...

They look very nice!
Are the heights on a real scale? I saw Africa-Europe image and it seems to
me that the elevations are exagerated, but perhaps I have a wrong intuition.

I'm not sure how you render the 1/60 degree topography with 1/30 degree
color with only 600Mb memory - according to my calculations this would
take more.
I'd strongly reduce the height exaggeration (with 2 km grid 5x-10x should
give quite pleasant results)

O.o;;
Wow. I wonder how I could get my hands on that...

It's very nice, but elevations are exaggerated, IMHO. A small tweak, I'm
sure.

You are right. With the correct scale, max elevation would be fraction of a
pixel at that resolution and thus rather imperceptible.

As explained in the text above the images, the height (and the atmosphere)
is scaled by a factor of 30.
Otherwise Earth would be boringly flat ;)

I know you did some similar things although I did not have the image
in memory very well. Gonna look at them again...

Let's see:
Topo is 1/60 degree, hence 21600 x 10800 pixels, i.e. 222 mega-pixels.
Thus, I need 444 Mb of height data (it's 2 byte).
Adding 1/30 degree RGB color, 10800 x 5400 x 3 = 167 Mb
Together, that's 611 Mb.
POVRay actually uses 620 Mb VM (according to the kernel).
I wonder where I could habe failed to calculate that correctly ;)

Hmm... Maybe I'll give it a try.
My Mars images use height exaggeration of 10. But Mars has more
extreme topography.

(Take the 2048x1536 JPEG to see the craters.)
