title: Is there a way to pre-render a virtual panoramic scene?
body: <p>I would like to put a photorealistic virtual scene on a tablet so when the user rotates the tablet, it shows as if the tablet is a window to an virtual world.</p>
  
  <p>Pre-rendered scenes can be rendered photorealistic, while real-time rendering has a "computer-made look". Given that for one scene, the POV can be rotated but not translated in space, is it possible that a pre-rendered virtual panoramic scene give an immersive impression?<br>
  I doubt that this is easy, since rotating the view point will cause some sort of distortion. This kind of distortion is easy for apps like Starwalk, but difficult for photos. Can anyone point me out a direction?</p>
  
  <p>I know that this will be tremendously easy for restricting motion in only one direction, but I would like the user to have a full 3d experience.</p>
