Thank you indeed, Stefan!
Yes, the size is small, mainly for render time purposes. My final image will
be much larger in any case, rendering in several successive stages over a
couple of days and reassembling everything afterwards.
Yes, the balloon is closer that it looks and its shadow is somewhere outside
the left border. I shall see what I can do... It is an important feature
because I intend it to be kind of scale element.

Yep! I thought I was being smart by keeping everything in one single
function :-)  Initially, it was a kind of exercise to increase my knowledge
of isosurfaces and the handling of them. In that sense, I am very satisfied.
In parallel, I did the same exercise using iso_csg, but I have not reached
as far, but the results are promising, and you have to think a little
differently.
By the way, although not vsisble in this scene, the cliff extends much
farther away. It bends to the left and goes off to the horizon. In a later
stage, I want to build a cliff with different offsets.
