Hi Robert, Your proposed solution is not what I really want. I would like to have a capability where I can alter the behaviour of the simulated time determination from within a plugin without write my own Viewer class. This allows me to use the OSG software as is without writing my own stuff.

From: [email protected] [mailto:[email protected]] On Behalf Of Robert Osfield Sent: Friday, March 21, 2014 10:05 AM To: OpenSceneGraph Users Subject: Re: [osg-users] Controlling simulated time HI Arend, The viewer::run() method is just a convenience method, which is great for small examples that want to illustrate other things than the make up for the frame loop, however, for full blown apps I would typically recommend just rolling your own frame loop. The next simplicist form of frame loop is to expand the viewer.run() method to something like: while(!viewer.done()) { viewer.frame(simulationTime); } To further expand it you'd have: while(!viewer.done()) { viewer.advance(simulationTime); viewer.eventTraversal(); viewer.updateTraversal(); viewer.renderingTraversals(); } You have access to all the source code of the OSG so I'd encourage you to look at the implementations on the Viewer::run() and Viewer::frame() methods so you see what is happening under the hood.

I have a pseudo loader plugin that interfaces the HLA world and manipulates the scene graph. What I basically want is the setting of the simulated start time and the time scale.
