Hi Robert -- in the osg/State header, the comment block for the setContextID()
method reads as follows:
/** Set the current OpenGL context uniqueID.
Note, it is the application developers responsibility to
set up unique ID for each OpenGL context. This value is
then used by osg::StateAttribute's and osg::Drawable's to
...
I suspect this is an old comment, as it has not been the application developer's
responsibility to set a unique ID for, well, I've been working with OSG since
2004 and I've never recalled having to do this, so at least 7 years.
I'd submit a change, but I'm not quite sure (upon glancing at the source) where
the unique ID comes from. If you would, could you update the comment to explain
how the unique ID is generated and set in modern OSG?
Thanks,
