What is 4-Point Interpolatory Subdivision Scheme about?

This document summarizes a 4-point interpolatory subdivision scheme for curve design proposed by Dyn, Levin, and Gregory. The scheme inserts intermediate points based on four consecutive control points. It is shown that for tension parameter w values between 0 and 1/4, the resulting curve is continuous, and for w between 0 and 1, the curve has continuous tangent vectors. Examples are provided to demonstrate how the scheme can be used for curve design and how the tension parameter controls shape. The scheme
