Sort of ... smoothness is achieved using more vertices where angle
crease limits cannot be set properly, but that's sort of a hack.
Making a surface smooth (in AC3D) generally implies setting a correct
crease angle, nothing more. Of course, that implies the base mesh should
have enough res first anyway.
The problem with AC3D is that you cannot customize the smoothness of
each edge at your please; you can only set a global per-object crease
angle that affects _all_ of the edges in the very same object (some will
be rendered smooth because of a low angle value, others will be rendered
with a crease because the angle is higher).
That's a little bit frustrating to me, 'cause I'm used to fine tune
those creases with much more freedom and much less effort :-(

Nice to see you already have some experience with this format. Can you
point out the basics? I mean:
- url of a file format description;
- url to basic osg file examples and capabilities;
- pros and cons of it.
Feel fre to post a complete description instead of a simple url, I will
appreciate that anyway :-)
