Hello, I'm trying to convert from model coordinates to screen coordinates with the following code: // Compute the model to screen transformation matrix osgUtil::SceneView* sv = m_sHandler->getSceneView(); osg::Matrix modelView = sv->getViewMatrix(); osg::Matrix projection = sv->getProjectionMatrix(); osg::Matrix window = sv->getViewport()->computeWindowMatrix(); osg::Matrix MVPW = modelView * projection * window; // convert a point in model coordinates to screen coordinates osg::Vec3 screenPoint = modelPoint * MVPW; The resulting screen coordinate point is correct in the x-dimension, but scaled down incorrectly in the y-dimension. The only point that is correct is the center point of the model. Am I missing a matrix somewhere? or does anyone have an alternate method of doing this? Yuen Helbig
