[osg-users] Pruning content

[Trajce Nikolov NICK]

Hi Jeremy,

to inject a custom visitor to the pager to modify loaded content, ideally
before caching to the file cache.

Actually there is a way. You can use database read callback and have your
visitor do stuff with the model when a tile/file is read in (paged in).
Have a look at:

osgDB::Registry::instance()->setReadFileCallback
osgDB::Registry::ReadFileCallback
