As Robert mentioned, OSG uses "loaders" to bring in files "from disk". Loaders are
plugins, which you can write, which take a "filename" and deliver a scene subgraph when
finished. However, nothing says that the filename has to be a filesystem path, or that the
data actually originates from a file on disk that is specified by that path. In my case,
the "filename" is a tile ID, encoded as a string. My plugin creates the data from both
in-memory and on-disk resources, and delivers the resulting data to the scene graph.
When the scene graph is not using the tile data, PagedLOD discards the scene subgraph
on its own, and when it is needed again, it calls the plugin to load/create the data again.
Thanks!, thats a good idea. We will study it.!

Sorry, I don't understand what you're asking there.
Thanks again.
