实现思路拆分

无限拆盒是怎么画出来的？

无限拆盒（Unboxing）用 JS 动态生成 3D 盒子，大盒打开露出小盒、再打开再露出更小的盒，循环不止；CSS perspective + preserve-3d 负责空间，JS 驱动盖子与四壁旋转。

说白了就三件事

  1. HTML：.scene 透视容器 + #cam 相机节点，右上角速度滑块与 reverse 按钮。
  2. CSS：固定视角 rotateX/Y，.box / .hinge / .face 分层 3D 结构。
  3. JavaScript：递归 createBox() 拼六面体；requestAnimationFrame 按相位缩放、开盖、倒墙、淡入淡出。

改速度动 slider 映射的 speed，改比例动 RATIO，改节奏动 LID_DURATION 等常量。

颜色为啥长这样

  • 背景：暖灰 #eee9e2
  • 盒面：半透明白 rgba(255,255,255,0.96) + 细黑描边
  • 控件：低对比灰字与细边框，不抢主体
  • 整体极简、纸模感

动起来是啥感觉

斜 45° 俯视一串嵌套白盒，像俄罗斯套娃式开箱。

  • 最前盒盖子先掀起，四壁向外倒下
  • 露出内部缩小的下一层盒，继续同样动作
  • 远处盒淡入、近处盒淡出，形成无限循环
  • 滑块调快慢，reverse 按钮反转拆盒方向
  • 约 0.4s 开盖 + 0.3s 倒墙，节奏干脆

怎么一层层画出来

3D 结构
  1. createBox()：floor + 四面墙（hinge 定位）+ back 面上的 lid。
  2. scale3d(RATIO^depth)：按层级指数缩小。
  3. .camera：整体 rotateX(-28deg) rotateY(32deg) 定视角。
动画相位
  1. phase 递增，每盒 depth = index - t 算进度。
  2. lid：rotateX 从 90° 扫到开盖角度，cosine ease。
  3. walls：延迟后 rotateX(-90deg) 倒下；alpha 远淡近淡。
