yes, the farthest-point voronoi diagram can be computed in time
O(n log n), by any optimal algorithm for 3D convex hull (not
a plane-sweep algorithm similar to fortune's)
take any classical textbook in computational geometry and you will
find the following information (for example, Shamos and Preparata's):
the farthest-point voronoi diagram (in the plane) is the projection
of the lower envelop of n (special) planes in 3D. The lower envelop is in fact

为什么拉里-伯德是有史以来最好的组织前锋，并且被认为可能是NBA历史上最好的传球
手，他是一个时代的象征。
或许，拉里-伯德不是烹饪大师。
然而，当持球时用他那冰冷的蓝眼睛观察防守，寻找极小而依然可为他所用的缝隙之际
，他就像场上厨艺最精湛的大厨，庖丁解牛般粉碎对手的防守；他传球精准，直击腹地
，结合了出色的视野，球感，篮球智商，无私，时间把握，以及创造力——无与伦比，
不可超越。
勒布朗-詹姆斯虽然是伟大无私的传球好手，可很轻易判断他跟拉里-伯德作为传球手
还不在同等级别。助攻数会误导人们，且包含部分主观色彩；也同球队风格，比赛节奏
和队友实力挂钩。
传球异常漂亮，可如果接球人丢了球，或错失了投篮，就算不上助攻。而当今，倾向于
