Maybe you could send your whole file. The code you inlined here seem right.

Robert. regards Oliver Oliver Kutter schrieb: Hi guys, I have a question concerning the openscenegraph example "osghud". I have a similar scene like this example except that I don't want to display hud text. Instead I want to render some small coordinate system axes like the ones in 3d studio max in the left bottom corner. I still use openscenegraph 1.2, but I think this is not important for my problem. Now my graph looks like this: I have a sceneview with a camera, a root node and the main scene as a child of the root node. Now I constructed my stuff like the osghud example: I added a new camera to the root node as a new subgraph and then I added my coordinates system axes model as a child to that camera so that the axes and the main scene are not connected. I set up the viewport of that camera (2nd viewport) to the left bottom corner with size (100,100) similar to 3d studio max. Finally, my axes are displayed in the 2nd viewport, but not in the main scene. That is correct so far. Now my problem is that not only the axes but also the main scene is displayed in the 2nd viewport. This shouldn't be like that because the main scene is not a child of the 2nd camera. What am I doing wrong? These are my parameters which I set to the camera: osg::ref_ptr<osg::Node> _axes = osgDB::readNodeFile("../data/osg/coordinate_axes.osg"); _camera->setProjectionMatrix(osg::Matrix::perspective(50.0, 1, 0.1, 10000.0)); _camera->setViewport(0,0,100,100); _camera->setReferenceFrame(osg::Transform::ABSOLUTE_RF); _camera->setRenderOrder(osg::CameraNode::POST_RENDER); _camera->setClearMask(GL_DEPTH_BUFFER_BIT); _camera->addChild(_axes.get()); _root->addChild(_camera.get()); best regards, Oliver ________________________________ _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g
