As others have mentioned, the DatabasePager might help, but the loading and
unloading of models is controlled entirely by LOD logic (eye distance or
pixel size) rather than your own logic. Below, you did not state that you
wanted to load the models based on LOD logic.
If you simply want to spawn a
HI Andreas,
As Serge suggested, it might just be far more productive to use the
OSG's built in database paging support. All you need to do is
decorate your subgraphs with a osg::PagedLOD or osg::ProxyNode, with
osg::PagedLOD being the method of choice as it'll do load balancing
for you - both loa
Did you looked at the DatabasePager ? It's made to load and unload models in
a separated thread and merge them to the scenegraph.
Take a look at osgDB::DatabasePager and osg::PagedLOD.

Thanks for your replies!
In my self-made thread I'm loading large 3d models and attaching them as PATs
to the scene graph (or removing them). If I do this in the main loop, the
loading process is interrupting the image generation. That's why I created the
thread and so I need a sync so that the

Hi Andreas,
Either put a mutex to do the sync before the call to
renderingTraversals() yourself or use a custom osg::Operation and
attach it to the viewer via viewer.addUpdateOpeation(). For the later
see the osgterrain's multi-threaded code path.

Hello everybody!
I have an application using the osgViewer::Viewer (OSG 2.4) and a self-made
thread, that has to modify the scene graph. To get no conflict I'm using a self
made mutex to lock the add/remove and frame function calls.
Now I want to know, if there is a built-in functionality to sy
