I've always like Tony DeRose and here he discusses the process of subdivision, averaging and such that they've used in computer animation.

At the end he discusses the weighting that allows for smooth curvature by identifying the limit that can be used in smoothing that just happens to be an equivalent to smoothing to infinity.

 

There is to be a follow up video but I don't think it's been posted yet.
