[osg-users] Follow an object
Hi, I am using a custom manipulator that translates and rotates the screen. I add a model as a node that is the base model and after that I add another model again as a node. I want this last added node to stay on screen while I rotate and translate the screen. In other words I want model to move with screen. How can I perform that action? Thank you!

Re: [osg-users] Follow an object
Hi, Have a look on HUD example. this is a way to add geometries to the camera, and so this geometry is always visible in the screen, at the same place. Hope this helps.

Re: [osg-users] Follow an object
Hi, I add geometries on the screen but when I use the manipulator to translate the scene I want that object to translate also. Like a a cockpit that ground and sky moves when rotate but the cockpit image stays on the scene. Thank you!

Re: [osg-users] Follow an object
In osgHud example, some text is rendered front to the camera, whatever the camera position/orientation is. You can replace the text using 3D geometries and keeping the same behavior. If this is not what you are looking, give us more explanations... Vincent.

Hi Tufan, You can use NodeTracker Manipulator, so you can track your origin node by your camera and manipulate your camera's rotation and oriantation due to your tracked node too. Regards.

Re: [osg-users] Follow an object
Hi, I use arrow keys to move scene by my custom manipulator. I found a code as in the following but I cannot use my manipulator when using NodeTrackerManipulator. osgGA::NodeTrackerManipulator::TrackerMode trackerMode = osgGA::NodeTrackerManipulator::NODE_CENTER_AND_ROTATION; osgGA::NodeTrackerManipulator::RotationMode rotationMode = osgGA::NodeTrackerManipulator::TRACKBALL; osg::ref_ptrosgGA::NodeTrackerManipulator tm = new osgGA::NodeTrackerManipulator; tm-setTrackerMode(trackerMode); tm-setRotationMode(rotationMode); tm-setMinimumDistance(50.0); tm-setTrackNode(NodeToTrack); viewer-setCameraManipulator(tm.get()); Thank you!

Re: [osg-users] Follow an object
Hi, This code works as I need that draws object on scene and does not move while I translate the scene but how can I add a node instead of a geode? I add directly the node but it did not seen on the screen. ref_ptrGeode HUD = addHUD(); ref_ptrStateSet stateSet = HUD-getOrCreateStateSet(); stateSet-setMode(GL_LIGHTING, osg::StateAttribute::OFF); stateSet-setMode(GL_DEPTH_TEST, osg::StateAttribute::OFF); stateSet-setRenderBinDetails(11, RenderBin); ref_ptrMatrixTransform modelviewAbs (new MatrixTransform); modelviewAbs-setReferenceFrame(Transform::ABSOLUTE_RF); modelviewAbs-setMatrix(Matrix::identity()); modelviewAbs-addChild(HUD.get()); ref_ptrProjection projection (new Projection()); projection-setMatrix(Matrix::ortho2D(0, 1280, 0, 1024)); //traits-width traits-height projection-addChild(modelviewAbs.get()); root-addChild(projection.get()); Thank you!
