viewer.run() -- это почти тоже самое, что и
viewer.realize(); while( !viewer.done() ) { viewer.frame() }
там только TrackballManipulator добавляется, если никакого не было.
Можешь посмотреть в OpenSceneGraph/src/osgViewer/Viewer.cpp

Hi guys!
I'm learning OSG and have a question how to move camera now because in
examples I see this
while( !viewer.done() )
{
viewer.getCamera()->setViewMatrix(seh->getCameraPosition());
// fire off the cull and draw traversals of the scene.
viewer.frame();
}
but now OSG use different approach
viewer.run();
so as I got I have to use callbacks - so my question how to use
updatecallbacks to move camera?
Thanx in advance
