[osg-users] Renderstages

[Kim C Bale]

At the moment I'm using a lot of post/pre render passes to generate a
series of effects and was looking toward cleaning up my code. I was
browsing the osgUtil lib and came across the renderstage class, it
sounds like I could use it to tidy up the structure of my graph. But I
don't really understand how they're used. 

Does anybody know of a good example where they're used outside of the
core osg libs? I didn't find anything in the example code. 

Cheers,

Kim.
