深深呼吸一口，那微风的凉润里，分明裹着一丝丝的甜暖，像是新翻的泥土，又像是从枯寂中沁出的缕缕草腥。这气息钻进鼻孔，并不急着往肺里去，倒先在喉咙里打个转，把那淤积了一冬的药罐子似的苦涩，悄然化开了许多。只觉得五脏六腑里那些被寒气淤塞的角落，此刻都被这无形且温柔的手，轻轻地疏通了、抚平了。心头那点莫名的怅惘，也像一块方糖，被这风慢慢地耐心地摇着，化在了一杯清冽的泉水里。
The quadtree is the two-dimensional case of a broader family of space-partitioning data structures. Octrees extend the same idea to three dimensions (splitting cubes into eight children), KD-trees use alternating axis-aligned splits (splitting along x, then y, then x again), and R-trees group nearby objects into bounding rectangles. Each variant makes different tradeoffs between construction time, query speed, and update cost.，推荐阅读safew官方版本下载获取更多信息
