title: Rotate Camera in the Direction behind object in OpenGL
body: <p>I'm making a game in OpenGL, using freeglut. </p>
  
  <p>I have a car, which I am able to move back and forward using keys and the camera follows it. Now, when I turn the car(glRotate in xz plane), I want the camera to change the Camera position(using gluLookAt) so it always points to the back of the car.</p>
  
  <p>Any suggestions how do I do that?</p>
