[osg-users] Issue using TrackballManipulator with GraphicsWindowEmbedded
Hey all. I'm having some trouble using TrackballManipulator with GraphicsWindowEmbedded. The two main problems are: * I have to pass normalized x,y coordinates (ie, x/width(), y/height()) to the graphics window's event queue. Looking at other examples, this doesn't seem right. * Zoom and Pan seem to be working, but Rotation just rotates around the plane that the window itself represents (so it rotates the view in 2D on the plane that has a normal in the camera's lookAt direction) I've set up the graphics window and viewer as follows: // setup viewer and window m_osg_viewer = new osgViewer::Viewer; m_osg_window = m_osg_viewer-setUpViewerAsEmbeddedInWindow(0,0,this-width(),this-height()); m_osg_window-getState()-setUseModelViewAndProjectionUniforms(true); m_osg_window-getState()-setUseVertexAttributeAliasing(true); m_osg_viewer-setCameraManipulator(new osgGA::TrackballManipulator); m_osg_viewer-setThreadingModel(osgViewer::Viewer::SingleThreaded); m_osg_viewer-setSceneData(groupRoot); In addition I've tried: * Setting an initial position and perspective matrix for the camera * Calling setMouseInputRange and setUseFixedMouseInputRange on the graphic window's event queue But they didn't have any effect. Am I just missing something obvious? Preet ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Ah, forgot to call viewer-realize() Sorry for the spam :) Preet On Sun, Jul 1, 2012 at 4:42 PM, Preet prismatic.proj...@gmail.com wrote: Hey all.
