Hi,
I posted a message about this on the 9th
(http://openscenegraph.net/pipermail/osg-users/2007-January/072777.html)
Basically:
- signalBeginFrame() set the pagers frame #
- updateSceneGraph() syncs the active and inactive PagedLOD lists (based
on frame number comparison)
- the cull traversal updates the frame # for visible PagedLODs.
If the order of operations is as above, then all PagedLODs are placed in
the inactive list since the pagers frame number is one ahead of the
PagedLOD frame number.
However I'm not sure what the correct solution is. osgProducer calls
updateSceneGraph before signalBeginFrame.

Robert, et. al.,
Can someone on this list confirm that the _activePagedLODList is indeed
the list of PagedLOD nodes that are completely outside of their PagedLOD
ranges (by moving the eyepoint very far away)? This can be verified by
uncommenting this line (around line 774) in DatabasePager.cpp.
//osg::notify(osg::NOTICE)<<"_activePagedLODList.size()="<<_activePagedLODList.size()<<"\t_inactivePagedLODList.size()="<<_inactivePagedLODList.size()<<std::endl;
If this can be confirmed then there is indeed a bug in
DatabasePager.cpp. If not, then the implementation is correct and I'll
have to try to figure out why my _activePagedLODList and
_inactivePagedLODList are backwards.
