That's a good suggestion that I missed.

Hi Hagen,
It does sounds like paging would help you out - as it'll manage the
loading of only visible items automatically. Creating a PagedLOD
based database would allow you to keep you app simple, with no need
for trying to be clever about picking what parts to load - it'll all
come free as part
@paul: Yes indeed. Thank you for the tip.
@Robert:
In my Application I have rooms and fixed camera-positions.
The Data I load in this application constist of loaded IVE-Files.
Every loaded node is a single object, but is composed by some subnodes i
dont care about.
Because Im loading many many fil
Hi Hagen,
Could you not just using the OSG's built in
osg::PagedLOD/osgDB::DatabasePager for managing the loading of your
scene in a more balanced way?
Robert.

I can only guess that either small feature culling or near plane

Hi,
In a small scene whose bounding sphere's radius is 300, I moved the eye point
near to a plane( the distance is about 6 ), then the scene behind the plane
could not be seen, this is a correct result.
However, when the scene turned to bigger( 5000 * 5000 ), the eye point was at
