What exactly does "update vertices via local averaging" means? Aren't vertices already set after we subdivide the mesh elements?

@bunbohue Hopefully this was cleared up with the lecture following this one, but Catmull-Clark and Loop refine the mesh by creating new vertices to generate a smoother mesh. Different refinement schemes involves different ways to average existing vertices to determine the position of new vertices (hence the phrase "update vertices via local averaging").
