   2D Image Rotation
  i am working on a 2d game using opengl...i would like to know a way to rotate an image from the center...currently i am getting a rotation from one of its corners...is there some way i could get the rotation from the center...   
  1. Translate the shape (a quad, presumably) to the origin, perform the rotation, and then translate it back. Or...2. Build your quads so that they're centered at the origin in local space (the better option, IMO).
