Take a look a osgDB::DatabasePager, which does essentially the same thing. Data (loaded in a separate thread) is stored in a list that is shared by the viewer class. Once a frame, the viewer lets the DatabasePager update the scene graph from this list. Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com <http://www.skew-matrix.com/> +1 303 859 9466

I would like that the physics and the graphic display would run in separate threads so that they could work independently without bothering each other. The communication between them is a kind of buffer or list to which the physics program pushes the last calculation and the graphic program pulls the appropriate one. I don't know which is the best (and most simple) way of setting up and managing the threads. Does the osgViewer class have a way of doing this? Where can I find an example which follows this technique? Thank you, Alfonso
