Try this:


class MyThread : public OpenThreads::Thread
{
public:
        MyThread(osg::Node** node) :
                _node(node) {}

        virtual ~MyThread() {}

        virtual void run() {
                *_node = osgDB::readNodeFile("cow.osg");
        }

protected:
        osg::Node**     _node;
};

int main() {
        volatile        osg::Node*              node = NULL;
                        osg::Group*             root = new osg::Group();

        MyThread*       myThread = new MyThread(&node);

        myThread->start();

        while(!node) {
                sleep(100);
        }

        root->addChild(node);

        osgViewer::Viewer viewer;

        root->addChild(node);
        viewer.setSceneData( root );

        viewer.addEventHandler(new osgViewer::ThreadingHandler);

        while(!viewer.done()) {
                //...
        }
}


Not tested, but should be close to it.
