title: How should I go about reflections in opengl?
body: <p>As far as I know there are 2 ways,</p>
  
  <ol>
  <li><p>"Flip" the scene on the y axis and add some blending - Avoiding this since I've added deferred rendering, which doesn't support transparency without mixing with forward rendering.</p></li>
  <li><p>Render the scene to a cube map and use the "reflect" function in GLSL - seems to be good for certain objects, but it's a plane I'm trying to do reflections with. </p></li>
  </ol>
  
  <p>Any suggestions? I've considered rendering the scene to an orthographic texture.</p>
