I'm just starting with OSG. I would like this (or similar) code: <div><br></div><div><div><div><div> int main() {</div><div> osgViewer::Viewer viewer;</div><div> osg::Geode* geode = new osg::Geode();</div><div> </div><div> viewer.setSceneData(geode);</div><div> geode->addDrawable(new osg::ShapeDrawable(new osg::Sphere(osg::Vec3(0, 0, 0), 1)));</div><div> </div><div> viewer.frame();</div><div> this_thread::sleep_for(seconds(2));</div><div> </div><div> geode->addDrawable(new osg::ShapeDrawable(new osg::Sphere(osg::Vec3(2, 0, 0), 1)));</div><div> </div><div> return viewer.run();</div><div> }</div></div></div></div><div><br></div><div>to display the first sphere and after 2s the second sphere, but it displays a blank screen for 2s instead and 2 spheres afterwards. What do I have to change?<br></div>
<p></p>
