You don't say what you are doing at the viewer level, but if you are using the OSG's standard CameraManiplators, including the default TrackballManipulator, the when the viewer initializes it'll compute the size of the scene it has to render and places the camera far away enough to ensure the scene is within the window, so if the scene is bigger the camera ends up further away.
Try creating an osg::Group and two different osg::Geometry as children that sit side by side, one large and one small and you should see the difference. -- You received this message because you are subscribed to the Google Groups "OpenSceneGraph Users" group.
