Hi Bruno, You could possible use the ReadFileCllback for this purpose. Have a look through the archives for discussions on the different ways that ReadFileCallback can be used.
However, I have to add the the DatabasePager is designed to dispatch compile operations to the draw traversal to compile the newly loaded subgraphs incrementally during each frame. A newly loaded subgraph isn't merged until all the GL objects in that subgraph have been compiled. This means you can't just switch off doing the rendering loop and wait for things to load and just render one frame and expect everything to merge right away. This incremental compilation exists to avoid frame drops. One way around this pre compilation would be to simply switch off pre compilation of subgraphs, this would be new subgraphs are merged in the frame right after it has been loaded. However, this approach increases the changes of a frame drop as the new data is rendered for the first time. There is support built into lazy update of the scene via the osgViewer::ViewerBase::setRunFrameScheme(...) support for the the osgViewer:::ViewerBase::ON_DEMAND option. When this is set and you use the Viewer::run() method the viewer will automatically only call frame when events have happened, there are animations running or the database requires a new frame to be done (including for the incremental compilation.) You could have a look at how this is implemented if you want to do something similar, or just use it directly. Robert.
