A control point
The limit curve
The control polygon
Works only for control nets whose faces are triangular.
The limit surfaces of Loop’s subdivision have continuous curvature almost everywhere.
The limit surfaces of the Butterfly subdivision are smooth but are nowhere twice differentiable.
Works for control nets of arbitrary topology. After one iteration, all the faces are quadrilateral.
The limit surfaces of Catmull-Clarks’s subdivision have continuous curvature almost everywhere.
