那天的月亮 | 月相观测网站 最近做了一个 side project：Lunaria 。 选日期、时间，在 3D 线框地球仪上点一个地点，就能看到那一刻、那个位置真实可见的月亮 —— 不是随便一张月相图，而是带月相、明暗交界、天平动和本地观测倾斜角的 3D 渲染。 技术栈：React + Three.js + astronomy-engine ，时区用 tz-lookup 处理，光照按站心天文计算。 几个我觉得有意思的点： 北半球盈月右亮、亏月左亮，和肉眼看到的一致 「本地观测角度」默认开启，按你在该地实际仰望时的倾斜呈现 可以生成分享卡片，内置「你出生那天的月亮」「我们相遇那夜的月亮」这类文案 在线体验： https://kokoro-ele.github.io/Lunaria/ 源码： https://github.com/kokoro-ele/Lunaria 欢迎来玩🌛
