一场由 Three.js 粒子系统 与 MediaPipe Hands 驱动的实时手势花园。手掌被摄像头捕捉后,21 个手部关键点会转化为一朵会呼吸的光粒子花:握拳时花瓣收拢成发光的苞,张掌时粒子向外绽放,花朵随掌心移动,并在指尖留下一枚微光。

只需要 Node.js 18+。所有前端依赖(Three.js、MediaPipe Hands、WASM 与模型文件)都已经放在 vendor/ 内,无需安装、无需构建、可以离线运行。

摄像头需要安全上下文:本机的 / 可以正常使用。如果从其他设备通过局域网 IP 访问,请改用 HTTPS。直接双击 index.html 以 file:// 打开无法使用摄像头,也无法加载 ES Module。

运行 node tools/test-gestures.mjs 或 npm test 可复现,关键点样本已经包含在 tools/fixtures/ 中,无需联网。
