[osg-users] [build] ViewerBase::setThreadingModel() not working

[Robert Osfield]

Hi Guy,

I have looked into the revision that Konstantin made back in January
and it looks to me like the intent was to prevent the viewer from
starting threads before you've called realize:

     https://github.com/openscenegraph/OpenSceneGraph/commit/bb84f1ea3c23625a645b9c2848202bca7c566efb#diff-936c2b7991f9f45a3c10c4d64a053ac2

Your suggestion is a more robust way of doing this so Ive applied this
and it works for me:

    https://github.com/openscenegraph/OpenSceneGraph/commit/ae3133522d18c1e456d22569137cdf45dac6b2f2

This change is merged with master and 3.6 branch.

Cheers,
Robert.
