WebInstead of keeping the mid-point of an edge as a vertex of the output polygon (as in mid-point smoothing), we keep two points. That is, the dual-point algorithm creates a new polygon by successively joining two points from each edge to corresponding points from other edges in the order encountered. WebThe Corner-Cutting Paradigm. Chaikin had a different idea. Researchers since Bézier had been working with curves generated by control polygons but had focused their analysis on the underlying analytical representation, frequently based upon Bernstein polynomials.Chaikin decided to develop algorithms that worked with the control polygon …
