Suppose an application that is not free-running the draw loop (because the data and view is unchanging unless the mouse is actively interacting with it). There are many PagedLOD nodes, and the databasepager can insert newly-loaded data into the scenegraph. However, the main cull/draw loop doesn't know that new data is now available for display, and neglects to redraw to incorporate it.
I was looking around because I thought I recalled a callback or something that could be intercepted to notify the application when DatabasePager::updateSceneGraph() completed and the new data had been added via addLoadedDataToSceneGraph(). I can't spot anything there though. Does anyone have any recommendations for how to detect this condition? I thought about just polling requiresUpdateSceneGraph() once per potential frame, but that's kind of crude. I could try to find a way to peek at the depth of the _dataToMergeList->_requestList it examines, and see if the value is decreasing, but that's pretty wonky too. Is there a Right Way?
