Hi, I've been reading similar problems, but I have not Found the solution ... the viewer is set in singlethreaded, and I added the GraphicsContext at the camera properly ...
Code: // construct the viewer. int width = 800; int height = 600; osgViewer::Viewer viewer; viewer.addEventHandler(keh); viewer.setCameraManipulator(new osgGA::TrackballManipulator()); viewer.setThreadingModel(osgViewer::Viewer::SingleThreaded); int xoffset = 40; int yoffset = 40; osg::ref_ptr<osg::GraphicsContext::Traits> traits = new osg::GraphicsContext::Traits; traits->x = xoffset + 0; traits->y = yoffset + 0; traits->width = 600; traits->height = 480; traits->windowDecoration = true; traits->doubleBuffer = true; traits->sharedContext = 0; osg::ref_ptr<osg::GraphicsContext> gc = osg::GraphicsContext::createGraphicsContext(traits.get()); osg::ref_ptr<osg::Camera> camera = new osg::Camera; camera->setGraphicsContext(gc.get()); camera->setViewport(new osg::Viewport(0,0, traits->width, traits->height)); GLenum buffer = traits->doubleBuffer ? GL_BACK : GL_FRONT; camera->setDrawBuffer(buffer); camera->setReadBuffer(buffer); // add this slave camera to the viewer, with a shift left of the projection matrix viewer.setCamera(camera.get()); viewer.setSceneData(scene); viewer.realize(); const char* vendorString = reinterpret_cast<const char*>(glGetString(GL_VENDOR)); //return NULL Why I can't access the graphics card info? Thank you!
