Thanks Gilles for this tip.
Unfortunatly, I lost too much precision so ... I have increased the
resolution of my image : thanks to POV to alway consider imported image
as 1x1 so, even if the high_field and the mapping resolution don't
match, the result is realy pretty good.
No, I'm playing w/ texture to find one looking like a forest shown from
the sky.
Bye
Laurent
