VRML Terrain Editing?

Does anyone possibly know of any decent freeware or opensource realistic
Terrain editors that can both export the mesh and the terrain textures
into VRML format? SO far I've only come across expensive US $1000+ 3D
animation packages that will do that and the only Freeware terrain
editors that I have come across will only export the mesh and not the
terrain textures.

Alternatively, does anyone know of any workflow process (e.g using
several different applications and techniques, etc) that can be used to
generate realistic terrain? I had a look at TER2BLEND and it's
associated notes, but that only covers creating 2D renderings in blender
and not 3D As far as I know, Terragen will only export the mesh and a
screen shot not the entire Terrain Texture.

Thanks for any pointers

How realistic? Like
http://www.vterrain.org/
?
Anyway, guess people on vtp list could know such a process.

For less realistic, I thought like this: get a satellite photo, from say
mars polar orbiter;) Or just draw your own. Lighter means higher...
quite simple. I wrote the code and I'm quite sattisfied with results. No
pics online but I can mail you pdf if you wish. The code is in cvs tree
at http://sf.net/projects/vrspace/ - vrmlclient package,
org.vrspace.vrmlclient.ImageTerrain.

Not really what you asked for eh?;)
Needs two jpegs (texture & elevation) instead of just one (elevation),
needs debug, needs UI, fractal subterrain generation is broken... and
it's very low on my priority list, so who wants to write some code, let
me know.

Realistic ? Hmm...

Terraform (Linux/UNIX/MacOSX maybe cygwin ?) can export a VRML file and
a texture from heightfield files. AFAIK you can combine both.

http://terraform.sourceforge.net/tf_features.html

It can also used to create heightfield files, but for creating realistic
things, i would use something like the erode command from hf-lab...

Well, I just tried the Terraform version which comes with my
Ubuntu/Linux (debian based) installation. It's Version 0.9.0 (says
the about box) and it can export a large list of formats
but no VRML! Do I need a extra plugin?

At version 0.9.0 (from source) i use

File -> Export -> View -> To File ... -> File type: |
V
VRML (*.vrml)

to export a matching png you can use as a texture, use the same dialog.

The "river" option in terraform is rubbish, you better use hf-lab for this.
