Re: [osg-users] LOD with ProxyNode vs. PagedLOD
The biggest difference is that the DatabasePager works with PagedLOD Nodes but not with ProxyNodes. You'd have to write your own paging thread or block rendering while you load. -Paul _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bradford, Chase Sent: Tuesday, February 19, 2008 8:25 AM To: [EMAIL PROTECTED] Subject: [osg-users] LOD with ProxyNode vs. PagedLOD Hey Everyone, Can anyone explain the significant differences between using an LOD that has many ProxyNode children for paging vs. a full PagedLOD node? Right now, the biggest benefit that I see for PagedLOD nodes is that they'll continue to shower lower quality children until the next higher is paged in, whereas the LOD with ProxyNodes would have popping effects.

PagedLOD provides load balance - such that subgraphs that are no longer being traversed can be marked as expired and removed from the scene graph. The osgDB::DatabasePager does all this pruning automatically for you. ProxyNode is just a ProxyNode for differing loading of a scene graph till its required, its very simple compared to PagedLOD and serves a very different purpose. If need a paged database use PagedLOD. Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] LOD with ProxyNode vs. PagedLOD
The ProxyNode isn't paged. It gets loaded and stays loaded. The PagedLODNode get's paged in / out based on distance from the camera.
