Hi Robert, Thanks for your help but I think I might have not asked my question very well. Regardless, I was able to find a solution to my problem. I case anybody wants my answer, it is below:
Using osgHud as a reference. 1) Set up the camera's projection matrix such that hud_camera->setProjectionMatrix(osg::Matrix::ortho2D(0, width_of_viewer, 0, height_of_viewer)); //the osgHud example gives some default numbers (0,1280,0,1024), but your geometry will deform if you shrink your viewer to be less than 1280 x 1024 //Note, I use qt's qwidget to hold my viewer so I just use qwidget->size() to obtain width and height 2) draw your geometry (use the osgHud rectangle that you draw text onto as a starting point) and add it to the camera. I also translate my geometry to the center of the screen which is just width_of_viewer/2, height_of_viewer/2 3) somehow capture the resize event of your viewer when it resizes. I use qt so I just use the QWidget::resizeEvent. 4) In your resize event function: hud_camera->setProjectionMatrix(osg::Matrix::ortho2D(0, new_viewer_width, 0, new_viewer_height)); And reposition your Geometry after. Luckily for me this is easy because I always want my geometry in the center: new_viewer_width/2, new_viewer_height/2 Your Geometry will now stay the same proportion AND size AND position (if you do everything I do) as it was in the beginning. It will not shrink or grow in any way on resize on the viewer/window.
