Thank you very much for your ideas!
I found out the osgDB::DatabasePager class by reading old posts and it looks
to fit my problem very well.
By using TerraPage I will have to pre-process my databases, whereas with the
database pager I don't need to.
float priority, const
Theoretically, I just have to use this function before the camera is close
enough to see next area(s).
