Hi Chris,
To experiment with different approaches to doing the releaseGLObjects()
call management I have created a RegistryRelease branch of the
OpenSceneGraph that is branched off the OpenSceneGrpaph-3.6 branch. This
branch just contains a single commit so far that wraps up:
1) Chnage of osgText::DefaultFont to use the osgDB::ObjectCache assigned
to the osgDB::Registry::instance() rather than a local static
ref_ptr<DefaultFont>
2) Change of osgViewer::Renderer::releaseGLObjects(State*) so that it
calls the osgDB::Registry::instance() that will in turn
call the osgDB::ObjectCache::releaseGLObjects(State*) which will in
turn
call DefaultFont::releaseGLObjects(State*)
3) Debug console output to track the creation, destruction and calls to
releaseGLObjects() of the various players above.
I've done some testing here to confirm that the
DefaultFont::relaseGLObjects() is now being called, but I don't have you
application usage case to thoroughly hammer it. So... I really need you to
test it at your end. If this works better then I can clean it up and get
it checked into the OpenSceneGraph-3.6 branch and master.
Cheers,
Robert.
