// 复制数组（避免原数组被修改影响其他测试）
Testing told me I used ~3,500 bytes for each frame - at 10 FPS, that’s ~35 KB/sec. While a nice T1 line could handle that, it’d easily saturate a 56k modem. And supporting even 1,000 clients would mean pushing 35 megabytes a second - way too much!

Every point gets examined, regardless of where it sits. Points on the opposite side of the map get the same treatment as points right next to the query region. We're doing a lot of unnecessary work.
