They aren't actually round. Look at the edges on her right breast against the dark background compared to how round her left breast looks. The mesh itself is quite angular still (though perhaps not as bad as Lora Croft), but the shader is using the colour's attached to each vertex to create a gradient that gives the impression of a smooth surface.

There's a maxim in computer graphics: if it looks right, it is right. This is a pretty good example. Lots more angles here than initially appears, but the overall effect looks rounded.

I see what you mean. If it werent for the edge with the dark background it would be hard to tell where the edges are at all.
