Hi(gh)!
Resuming my "Whatmough" planet project from 2011, I would like to know
if is possible to create realistic mountain ranges (on a continental
scale) with believable drainage patterns using procedural functions. I
tried ridged_mf(), but got nothing even remotely resembling this.
Another (but very time-consuming) approach would be "painting"
topography manually, using 16-bit grayscale PNG heightfields. Are there
any heightfield editors for this bit depth around?
See you in Khyberspace!

As a last resort:
I have 3 programs at my site that helps make height fields and place objects on
them. They where All wrote for my old Win98, but they run on my new WinXP.
The first program lets you use contour lines to make a height field image in
tga(8bit) or ppm(16bit). The next one lets you rough up images made by the
first.
The last one Lets you place things on a height field made by using the Image
from the first two.
I'm here at https://leroyspovstuff.yolasite.com/
Have Fun!

A long time dream indeed. Third party programs approach that dream;
alas, the better ones are not free.
I own GeoControl, which has been succeeded by World Creator from the
same makers. As far as I know, it is one of the best programs for a
reasonable price. http://www.bitethebytes.net/bitethebytes/
L3DT is another one - which I never tried - but with a free version.

Some people keep things that work.
Going from Leroy's site. It was new in 2006

Not really useful, at least not in its current development stage - no
zoom view and therefore no chance to exactly place the cursor. Perhaps
it is because I used Windows 7 rather than XP, I don't know...
The fine editor (the second program) is not even downloadable at all!
Nevertheless, thanks for your tip!
See you in Khyberspace!

I forgot to mention that I use either Windows XP Professional (32-bit),
Windows 7 64-bit Professional or Debian Linux 8.9, so that software
exclusively written for Windows 8 or newer unfortunately would be of no
use to me.
See you in Khyberspace!

Does World Creator export to 16-bit PNG as used with POV-Ray? As I need
to build VERY large heightfields (to be wrapped around spheres as meshes
afterwards), I would need the Professional Edition - which at 289$, at
least for the moment, is out of reach for me.

Sounds very promising, but again only with the Professional version -
which, on the other hand, at 34.95$ for the "Indie" license is
affordable to me. But I never ordered anything from the US - there maybe
a couple of pitfalls... I remember having ordered two organ player's
textbooks from Switzerland (a non-euro country), which were priced at 5
SFR each one (about 7 euros back then), but including shipping and
exchange fees, it ended up at a whopping 22 euros...

I will give it a try... just downloaded it! The planet on the web page
did not look very realistic (when it comes to height distribution)...
but at least it exports explicitly to POV-Ray and uses 16-bit PNG
grayscale images!
> http://www.daylongraphics.com/ (not free)
Also not too expensive... and it works with POV-Ray!

Terragen! An old friend, which I used already back in 1999 and which in
fact was the basis for my very first animations!
And the version 4 looks almost like a system usable for Khyberspace on
its own... at least with its commercial sub-versions, which of course
are exceptionally high-priced but probably worth it all!
But even the free version is VERY promising! I just downloaded it...
> http://www.fracterra.com/wilbur.html (free)
Amazing! Almost perfect... or purrfect, as an ailurophile like me would
put it! I've not only downloaded it, I already started to play around
with it! However, the POV-Ray 16-bit TGA export turned out to be faulty,
but that's no big issue, as it also exports to 16-bit PNG!

I did not try this yet, as I probably will be occupied with Wilbur for
the next weeks!
Thank you very, very much, Thomas!
See you in Khyberspace!

I wondered if there were povers still using 32 bits.

I do not own World Creator, so I cannot answer that question. GeoControl
(the ancient version that I have) does not but has a well-behaved tga
export.

With a credit card or similar that should not be a problem, otherwise...

You are welcome Yadgar. Glad to be of help. I hope you will find what
you want. If there is something fundamental that I have learned since I
started modelling (with POV-Ray of course!) back in the nineties, it is
that for each scale you often need a different tool/procedure. It is
almost impossible to use the same output for a planetary view /and/ for
a landscape. Both need different approaches.
