title: Terrain minimap in OpenGL?
body: <p>So I have what is essentially a game...  There is terrain in this game.  I'd like to be able to create a top-down view minimap so that the "player" can see where they are going.  I'm doing some shading etc on the terrain so I'd like that to show up in the minimap as well.  It seems like I just need to create a second camera and somehow get that camera's display to show up in a specific box.  I'm also thinking something like a mirror would work.  </p>
  
  <p>I'm looking for approaches that I could take that would essentially give me the same view I currently have, just top down...  Does this seem feasible?  Feel free to ask questions... Thanks!  </p>
