Generally, the master.flt does not have any knowledge about the location
and extents of the external files that it calls.
This is the information that the pager would require.
What we do is to run a separate app that runs through all of the db tiles
one time, and creates a text file of the filenames and extents.
This can then be used to create an osg file with pagedlod nodes. Each
pagedlod node would reference a filename from the
list, and contain the center point, etc. information.
Once these pagelod nodes are created, OSG will take care of the rest
through its paging support.

Hi, Im new to osg and I have an Openflight database, it has
a master.flt and would like to use osg to page it in rather
than loading all in memory at once . I'm not sure if
osgviewer is doing this already? or wether I should use
osgpagedLOD example to load in my database - if so how?
Also down the track I would like to know which tiles are
being loaded in and which tiles are being loaded out. Where
would I be able to find the relevant point in the source
code?
Thank you and Merry Xmas
