Hi,
I think the most secured way is to do it like that :
while( !viewer.done() )
> {
> viewer.sync();
> viewer.update();
>
> modify_scene_graph();
>
> viewer.frame();
> }

If I'm good, the callback allow safe graph modifications, but only on node
children... so depending on what you need, that can be a solution too.
The subject have been discussed lots of time on the mailing list, so check
the archive and you will find some good informations.

Vincent.
