Hi,

CLipka mentioned, that with some PIGMENT function it should be possible
to create a heightfield from a heightfield image, that is twisted like a
cylinder.

I want to go ahead with that, but need more information on that
function. Can anyone assist me?

You do use the HF_Cylinder macro, using a function that is defined in
terms of a pigment -- a so-called pigment function.

For details, look it up in the docs.

Thanks for this signpost, CLipka. Will research into that direction. :-)

Yes, that is a great headline for a good thread, and CLipka will -
without any doubt - like it! :-)
He must be, by now, very much fond of such headlines! :-D :-D :-D

Maybe he even meant to write "Loch", who knows.
I assisted him with a little correction.
