Hi Vincent, The osgViewer library has built in support for doing multiple screens/contexts, I would recommend using this, rather than trying to cook your own solution for it. It is possible to have your app provided the window and let the OSG create the GLX context for each window, so this might well be the best solution for integrating with your Motif widgets, but you could easily keep the Motify GUI and the actual 3D rendering entirely separate so integration might not be neccessary.
As you don't say anything about how you integrate the OSG and Motify or what OSG version you are using I can't make any specific recommendations on how to do it. Robert.
