I've got what may seem a stupid question...
When I subdivide a mesh, all it does is add more vertices to it.
So far so good, you may say...
But let's say I've created a bowl, made from a sphere cut in two halves.
At this point, I notice that it's still not round and smooth enough (Fig.1 below represents a detail of the mesh)
=> If I subdivide it, I'll certainly get more vertices, but it won't make it any smoother. (Fig.2 - new vertices represented in green)
Is there an option to have Blender re-calculate the position of the new vertices so I can get a smoother mesh - as shown in Fig.3?
(without of course re-subsurfing the whole thing)
Thanks guys!

Sorry for the poor quality of the image, but I'm at work, so I had to do it with MS Paint...
