The arbitrary-looking barycenter formula was chosen by Catmull and Clark based on the aesthetic appearance of the resulting surfaces rather than on a mathematical derivation, although they do go to great lengths to rigorously show that the method converges to bicubic B-spline surfaces. Repeated subdivision results in meshes that are more and more rounded. less "jagged" or "pointy") than the old mesh. The new mesh will generally look "smoother" (i.e. The new mesh will consist only of quadrilaterals, which in general will not be planar.
