[osg-users] How to check if pagedLod already exists in databasepager with same filename

[Simone Rapposelli]

Hi Robert,

thank you for your fast reply.
My problem is that osgDB::ReaderWriter::ReadResult readNode(const std::string &fileName, const osgDB::ReaderWriter::Options *options) gets called even if a PagedLod with the same fileName has been previously loaded: for example, this happens if I move to any position on the viewer and then come back.
Thus, inside this function I need to check if any of the PagedLod currently loaded in DatabasePager has the same fileName of the passed argument: in this case I could avoid to reload data already in memory.

Thank you!

Cheers,
Simone
