First hello to this newgroup, as a new user i am pleased to meet you.
I have trouble making run geomorph under windows since it seems to miss
important includes.
However could you tell me where i can find tutorials on bumpy terrains on the
net or provide me a sample to begin with ?

I can't help with Geomorph as I've never used it.

There are quite a few different approaches. I did a quick Google, but didn't
spot any tutorials, though I had a feeling that Christoph Hormann had done a
good tutorial on this sort of thing a few years back.
There are some utilities that can generate bumpy terrains as height_fields.
You can generate height fields using POV-Ray textures. There's a recent
addition to the Object Collection at
http://lib.povray.org/searchcollection/index2.php?objectName=TextureGen&version=1.0&contributorTag=worldbuilder
that illustrates how to generate height_fields that seamlessly tile
horizontally. When I saw it I added a little writeup on it here:
http://lib.povray.org/collection/texturegen/worldbuilder%201.0/texturegen.html.
Although it looks like it was primarily intended for generating planets and
asteroids, you could use a crackle pattern with that scene file to generate
a heightfield with a cracked surface.
If you don't need actual cracks that you can 'look' into, you may be able to
simulate them using a highly accentuated crackle pattern as a surface
normal.
Otherwise IsoSurfaces and meshes can be used to generate terrain. I'm
currently doing some work with the elevation data published by the US
Geological Survey at http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/Eurasia/
which contains binary data for every type of landscape on earth. I've
converted the UK data into mesh2 objects. If that sort of thing interests
you I'd be happy to share my scripts or convert a small section of data for
you.
Regards,
Chris B.

But one thing I did come across was a sample scene file by Kirk Andrews at
http://news.povray.org/povray.binaries.images/attachment/%3Cweb.4ac2c552a7005b411322341f0@news.povray.org%3E/landscapetutorial.pov.txt
that uses a function as a height_field to generate a POV-Ray landscape.
(I've not tried it myself). That could provide you with a starting point.

Chris B.

Thanks for mentioning my map generator. There's a new version out, one that also
has color maps and specular maps.
