The reason why the model is based on Voronoi diagram and Delaunay triangulation is that one of the main factors of directional relationships is visible field of two objects, and the visible field is adjacent part of two object, so direction calculation of two objects may be limited in the adjacent field.

模型的建立之所以借助于Delaunay三角網和Voronoi圖建立空間方向關系計算和描述模型啊啊啊好大爽被插乱伦视频，是因為決定兩目標之間的空間方向關系的主要因素之一是這兩個目標之間的可視區(qū)域欧美亚洲综合另类国产情拍图，而可視區(qū)域恰好是它們的鄰近區(qū)域女生的鸡鸡的黄色视频，因而兩目標的空間方向計算問題可以歸結為目標間鄰近區(qū)域內的問題免费又大又粗又爽的视频。
