物理遮蔽光线，永远比纯靠前置摄像头识别人脸去隐藏通知或是干脆贴上物理的光栅防窥膜来得更彻底。这项技术一旦铺开，那些劣质防窥膜大概率会被彻底扫进历史的垃圾堆。

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.
