I am new to OSG and have a similar problem. Running osgviewer on archive.txp
doesn't show any visual output, even if I change LOD settings or hold down the

I wouldn't recommend using osgText::TextNode right now as it's not yet
feature complete. It's better to use osgText::Text or

The DatabasePager already has a scheme for load balancing and will

The latest version of VPB has all the code you need to generate mip maps for an

Hi Alex,
Just because children of a PagedLOD may be out of range doesn't mean
that the PageLOD itself isn't required in memory, if the cull
traversal is hitting the PagedLOD it's active an really can't be
expired, even if the children are being culled at that point in time.
I rather feel that
