Yes, that's the advantage of open source. BTW, I have lately heard
people call Targetware and MSFS/CFS open source because you can mod
it, but of course that is very different to having the program source
in the open.

Regarding the visuals, the easiest way is use an existing model and
convert it.

I did that a long time ago, before the LinuxTag trade fair.
It is in PPE (the open source modelle PrettyPolyEdit, which sits on
top of the library PLIB, like FGFS does). You look at the terrain from
above. Of course you can rotate and move the camera. You then simple
click the mouse onto the spot you want to add the model. You then have
three dials to edit the pitch rolll and yaw if possible. For example,
with taildraggers converted from MSFS, they are normally horizontal
and you have to rotate in pitch until all wheels are on the ground.

I am not sure anyone used this apart from me.
This should still work, but it uses ascii terra gear scenery. I do not
know the status on that. Is there a converter?

>What 3D formats and apps are used?

See the bottom of this page for file formats:
http://plib.sourceforge.net/ssg/non_class.html
In the big table, look for formats we can load.

Bye bye,
Wolfram.
