Hello !
Just managed to create this. The terrain is a blend between image data
and a granite pattern. I had to write a cubic interpolation script
myself since it is apparently not available yet in POV... There still
are some artifacts, but it used to be quite worse.
I guess I'll have to add some clouds now. But I'm having a hard time
with media...
Comments and suggestions welcomed

This is a good example of blending data for height_fields. I think one
could get away with a lower-resolution image if it was perhaps given
some turbulence...
Good job on the cubic interpolation... how is it referenced in the POV
script, 'interpolate 3'?

Well, it should be judging from the file image.h in the POV source. But
as far as I know, it is not implemented in v3.5. So I coded the
interpolation in POV script language. And obviously it's quite slow
compared to the built-in interpolation types. But on the other hand,
this gives me the possibility to tweak the interpolation process...
Anyway, I'm not ready to recompile POV yet. So I guess I'll keep using
my script ;-)
Thanks for the comments
