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.，详情可参考heLLoword翻译官方下载

It's always a fun day for the space nerds when a NASA team has new images to share from the James Webb Space Telescope. Today's pair has brains on the brain, with a look at the fittingly named Exposed Cranium Nebula. More officially, this cloud of space dust and debris is known as Nebula PMR 1. The images shared today may capture a moment in the final stages of a star, as well as giving hints as to how the nebula got its brain-like shape.
