Hi Sebastian,
Is this approach still valid with lots of little nodes that have no
LOD detail against them? Or should I just tell my brain that the LOD
part of the node isn't really applicable for what I'm doing and
continue with your advice?
If they are spatial separated/clustered it might help. You only gave us
the number of nodes, not how many are visible at a time or how they
distributed.
Maybe describe your structure a bit more detailed.
Cheers
Sebastian
Thanks, Sam

Hi Sam,
Hi All,
I'm attempting to formulate the best way to stream in nodes that
make up regions. These regions normally consist of anywhere
between 4,000 to 6,000 nodes and end getting stitched together.
My question is: Is the PagedLOD node what I want to use? I'm a
little confused as to how the paging stuff works in OSG. Do I
need to generate a tree (KD? Quad?). Do I then need to populate
the tree and allow OSG to do its thing? Any guidance would be
much appreciated.
The paging is done via DataBase pager. You can leverage its power
by using osg::PagedLOD. Try to organize your nodes in a quadtree
and reference the contained regions with an pagedLOD.
The pager will load them in the background.
Cheers
Sebastian
Thanks.
