Hi Ulrich, Thank you again for your patience and insight. Your code makes absolute sense. But I still get the same result. If I have no trackball manipulator for either view, I get a black screen. When I have set it up for one view, only that view gets an image. My code:
Code: osg::Group* scene = new osg::Group(); osg::Node* groundNode = NULL; osg::Node* tankNode = NULL; groundNode = osgDB::readNodeFile("cow.osg"); scene->addChild(groundNode); osgGA::TrackballManipulator* Tman = new osgGA::TrackballManipulator; // construct the viewer. osgViewer::CompositeViewer viewer(arguments); if (arguments.read("-2")) { // view one { osg::Camera* camera = new osg::Camera; osgViewer::View* view = new osgViewer::View; view->setName("View one"); viewer.addView(view); view->setUpViewOnSingleScreen(0); view->setSceneData(scene); // Get the scene bounding sphere osg::BoundingSphere bsph = scene->getBound(); // Look at the center of the scene osg::Vec3 lookAt = bsph.center(); // Place eye at an appropriate distance 'south' of the look-at point osg::Vec3 eyef = lookAt + osg::Vec3(0,-1,0) * bsph.radius() * 3.5f; // Set camera view matrix camera->setViewMatrixAsLookAt(eyef, lookAt, osg::Vec3(0,0,1)); view->setCamera(camera); } // view two { osg::Camera* camera = new osg::Camera; osgViewer::View* view = new osgViewer::View; view->setName("View two"); viewer.addView(view); view->setUpViewOnSingleScreen(1); view->setSceneData(scene); // Get the scene bounding sphere osg::BoundingSphere bsph = scene->getBound(); // Look at the center of the scene osg::Vec3 lookAt = bsph.center(); // Place eye at an appropriate distance 'south' of the look-at point osg::Vec3 eyef = lookAt + osg::Vec3(0,-1,0) * bsph.radius() * 1.5f; // Set camera view matrix camera->setViewMatrixAsLookAt(eyef, lookAt, osg::Vec3(0,0,1)); view->setCamera(camera); //view->setCameraManipulator(Tman); } } viewer.realize(); while(!viewer.done()) { viewer.frame(); } I must be missing something obvious I guess, but for me it isn't obvious (yet). Thank you!
