title: it is possible to only move camera in opengl without redrawing the scene?
body: <p>I'm creating a very render expensive scene in opengl (using vertex buffer objects) and while all objects stay in place, I want to do something like a 'smooth pursuit' of the objects. That is: leave the objects where they are and move the camera / point of view to the left or right with a certain constant speed. Currently I do this by calling <code>glTranslatef</code> in my <code>draw</code> function, followed by code which re-draws all objects. This is however very expensive (lot's of objects!). Is there a way to just move the camera, without redrawing the entire scene?</p>
