[osg-users] How to abort rendering

Hi Claudio,

There is an rendering abort feature built into osg::State.  You can
have a global bool that you tell osg::State about via

This is crude sledge hammer though, it's meant for handling a user
pressing escape or similar abort.  Whether this is appropriate for you
usage I can't say.

The alternative would be to implement your own RenderBin variants that
have you won early abort mechanism built in.

However, unless you really really must have this feature and you have
proven beyond doubt that it' absolutely required then I'd suggest just
getting on with developing your application and just making sure it's
efficient rather than jump throw hoops because you think a feature
might be required.
