My application utilizes a osg::PagedLOD node for terrain that is shared across
multiple osgViewer::Viewer instances. The terrain paging works beautifully
when I only have a single window open; however, there are issues whenever I
open a second window.
Some of the issues I see are:
1) Window 1 appears to revert to the lowest LOD
2) Window 1 and 2 seem to "flicker" as if fighting over which texture or tile
should be visible
3) Sometimes window 2 textures are missing for some tiles (i.e. white
I suspect that I might be using osgDB::DatabasePager improperly. I have tried
sharing the same osgDB::DatabasePager across all osgViewer::Viewer instances,
and I have also tried using a unique osgDB::DatabasePager for each
osgViewer::Viewer instance. What is the correct approach?
Any ideas as to what I am doing wrong? Any suggestions for me to try?
I am using OSG 2.4.
