I usually just use what comes with the linux distro, in my case that is 
currently still Fedora 23, that would mean boost 1.59.0 (I think).

I'm not deeply familiar with OpenSceneGraph. I would imagine the level 
of abstraction is somewhat comparable. In general scene graphs have 
fallen a bit out of favor and game engines become more popular as the 
basis for interactive applications. What makes the most sense (as ever 
;) ) depends on your application.

Hmm, looks like this is making use of boost atomic internals which 
appear to have changed in more recent boost. This would require a little 
bit of investigation to find out what the replacement should be.

Cheers,
Carsten
