I used OSG 1.2 before and didn't meet problems like this. I've just tried OSG 2.2 with VS 2005 SP1, a simple code: loading a model. The code like this: osg::ref_ptr<osg::Node> m_Node = new osg::Node(); osg::ref_ptr<osg::Group> root = NULL; osgViewer::Viewer viewer; osg::Vec3 nodePosit; osg::ref_ptr<osg::PositionAttitudeTransform> nodeXform = NULL;
m_Node = osgDB::readNodeFile("box.flt"); root = new osg::Group(); nodeXform = new osg::PositionAttitudeTransform(); root->addChild(nodeXform.get()); nodeXform->addChild(m_Node.get()); nodePosit.set(5,0,0); nodeXform->setPosition( nodePosit ); viewer.setCameraManipulator(new osgGA::TrackballManipulator()); viewer.setSceneData( root.get() ); viewer.realize(); viewer.run(); I duplicated files in lib Folder and add 'd' before the extension. When I built it in Debug mode, it had no error but then I received a message: http://i58.photobucket.com/albums/g278/TTFTotti/error1.png Additional to it, when I built in Release mode, it run, the model loaded, I still could rotate and zoom the object, but I couldn't view wireframe, switch full-screen, windowed mode like I did with the old version. And I received a message in console window: Error: [screen #0] ChooseMatchingPixelFormat() - Unable to choose the requested pixel format http://i58.photobucket.com/albums/g278/TTFTotti/error.png Please show me the way to solve it.
