At quick glance, a couple of things look suspect in the code below... Try setting traits->doubleBuffer = true;
Also when you create the graphics context, you're passing in "traits" instead of traits.get(). I would think it would be the latter since traits is a ref_ptr... -Shayne -----Original Message----- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Vic Ace Sent: Friday, July 24, 2009 9:34 AM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Help with CompositeViewer I have been looking at this example (http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/exa mples/osgcompositeviewer/osgcompositeviewer.cpp) and written code similar to the parts that I think are relevant but all I get inside my window is a plain black background. I have set it to display a blue background and given it a capsule to render but none of that is displayed. Have I missed something really obvious? Code: osg::ref_ptr<osgViewer::CompositeViewer> viewer = new osgViewer::CompositeViewer; osg::ref_ptr<osg::GraphicsContext::Traits> traits = new osg::GraphicsContext::Traits; traits->x = 100; traits->y = 100; traits->width = 800; traits->height = 600; traits->depth = 16; traits->windowDecoration = true; traits->supportsResize = false; traits->windowName = "TEST"; osg::ref_ptr<osg::GraphicsContext> graphicscontext = osg::GraphicsContext::createGraphicsContext(traits); if (graphicscontext.valid()) { graphicscontext->setClearColor(osg::Vec4f(0.2f, 0.2f, 0.6f, 1.0f)); graphicscontext->setClearMask(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); } osg::ref_ptr<osg::Group> root = new osg::Group(); osg::ref_ptr<osg::Geode> geode = new osg::Geode; osg::ref_ptr<osg::Capsule> capsule = new osg::Capsule(osg::Vec3(), 1, 2); osg::ref_ptr<osg::ShapeDrawable> drawable = new osg::ShapeDrawable(capsule); geode->addDrawable(drawable); root->addChild(geode); osg::ref_ptr<osgViewer::View> view = new osgViewer::View; viewer->addView(view); view->setSceneData(root); view->getCamera()->setGraphicsContext(graphicscontext); viewer->run(); Thanks! ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=15397#15397 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
