I've only recently started using OpenSceneGraph, so am probably mistaken about this, but I feel there's some issues with osgDB::DatabasePager. It seems the design of osgDB::DatabasePager allows for multiple instances of it to exist side-by-side. Scene creates one instance in it's constructor, and if you call Registry::getOrCreateDatabasePager without setting a pager up, it creates another instance. The first uses the Database::create function, whereas the second uses a simple 'new'.
This has caused us some issues as we only expected there to be a single instance of osgDB::DatabasePager. What is the reason for explicitly allowing this functionality? It may simply be to do with the way we have the DatabasePager setup, but my lack of a higher view of the code is making it hard to understand what's supposed to happen. Can anyone clarify how the DatabasePager is supposed to be used for me? Kind regards, Rick Appleton
