摘要
An algorithm is described for the construction in real-time of the convex hull of a set of n points in the plane. Using an appropriate data structure, the algorithm constructs the convex hull by successive updates, each taking time O(log n), thereby achieving a total processing time O(n log n). © 1979, ACM.
