Hi(gh)!

Once more with POVSolar again... attached below, you see a rendering of 
the Martian moon Deimos, generated from a 16-bit TGA heightfield, which 
in turn was made from a color-coded topographic map of Deimos, processed 
with the GIMP and John Beale's HF-Lab.

But one problem remains: where the eastern and western edges of the 
simple cylindrical map meet, an ugly seam running from pole to pole 
shows up - and, as I tested before, it's neither because of non-equal 
colour values at the first and last column of pixels in the TGA map, nor 
because of erroneous calculation of local radii.

But what else?

See you in Khyberspace!
