Hello everyone,

Nicolas, thank you for your email and your work.

The Ogre files have been generated mostly from 3ds scenes, some from 
VRML scenes. I doubt we can find appropriate version of the source files 
somewhere, plus we would also need appropriate dot scene exporter (there 
are hundreds of versions for 3ds max, each with pros and cons, but none 
is recognized as a "standard").

Anyway, if that can help, the source files are for sure, either self 
created by people at INRIA (as for the TIE fighter hangar or the handbal 
gymnasium for instance), or freely available models (as for the 
TIE-fighter model or the 3D head model -taken from Tempo- for instance).

If we can't provide appropriate sources, I believe you should consider 
them non-free. If that's a matter for debian packaging, you may consider 
not including the VR demos.

About the font, yes you can change it to whatever font is provided with 
the system :)

I hope this helps,
Best regards,
Yann
