这段代码实现了一个完整的分步原理动画，包含以下核心特性：

视觉设计

  • 深色工程蓝图风格背景，带微妙网格纹理
  • 铜柱采用金属渐变填充，掩膜板用蓝色调区分，真空气流为青色，超声波为紫色
  • 每个关键力/效应都有独立的颜色编码与辉光滤镜

六步动画时序

  1. 贴合掩膜板 — 从上方滑入并贴合，带缓动动画
  2. 开启真空 — 气流箭头出现并持续流动，显示真空度
  3. 撒布铜柱 — 30个铜柱受重力散落在掩膜板表面
  4. 超声波振动 — 核心阶段：目标铜柱在声流效应+漏斗引导+真空牵引下自组织入孔，两侧波纹可视化振动，掩膜板微振
  5. 吹气清理 — 未入孔铜柱被吹走，已入孔铜柱保留
  6. 移除掩膜板 — 掩膜板升起，露出精准就位的铜柱

IFR 思想体现

  • 直接展示最终理想解：铜柱"自己找到"正确位置，无需逐根机械对准
  • 右下角局部放大视图（×40）清晰展示 0.13→0.12mm 缩径处的"架桥"风险
  • 45° 收敛角、Φ0.5→Φ0.13 漏斗扩大效果均有尺寸标注

交互控制

  • 上一步/下一步按钮逐步推进
  • 自动播放模式
  • 超声频率滑块（20–40 kHz）实时影响振动幅度与速度
  • 真空度滑块影响铜柱吸引力强度

这次我完全重写了动画代码，修复了以下关键问题：

修复内容：

  1. SVG 滤镜定义 — 重写了 feMerge 的创建方式，确保两个 feMergeNode 正确嵌套在 feMerge 内
  2. 铜柱状态机 — 简化为清晰的状态流转：wait → fall → onmask → vibrate → funnel → fallhole → seated，每个状态都有明确的进入条件和时间驱动
  3. 去除未定义变量 — 之前的 p.vibDx 从未定义，导致运行时错误；现在振动偏移直接在渲染时计算
  4. 掩膜板绘制 — 漏斗孔的路径坐标经过重新计算，确保视觉上正确

动画流程（6步）：

步骤 内容 视觉效果
1 贴合掩膜板 掩膜板从上方滑入，带缓动动画
2 开启真空 青色气流箭头出现并持续流动，显示真空度
3 撒布铜柱 20个铜柱从上方受重力落下散布在掩膜板上
4 超声波振动 5个目标铜柱振动移向漏斗中心→沿漏斗下滑→穿过玻璃孔入位（绿色闪光）
5 吹气清理 非目标铜柱被吹飞，局部放大视图展示缩径风险
6 移除掩膜板 掩膜板升起，露出精准就位的铜柱 + 完成标注

交互控制： 超声频率滑块影响振动幅度与移速，真空度滑块影响吸引力强度，均实时生效。

这个版本修复了之前的所有问题，主要改进：

修复的关键 Bug

  • 移除了未定义的 p.vibDx 引用（这是导致动画崩溃的根本原因）
  • 重写了铜柱动画系统，使用确定性的插值动画替代物理模拟，避免了状态机中的竞态条件
  • 修复了掩膜板组引用和清理逻辑

动画系统重构

  • 每个铜柱现在使用 state + progress 的确定性动画：fall → surf → attract → funnel → seat
  • 目标铜柱带有延迟（delay），错开入孔时间，视觉效果更清晰
  • 振动效果使用全局时间 S.gt 和频率参数计算，不依赖物理积分

六步完整时序

  1. 掩膜板从上方缓动滑入贴合
  2. 气流箭头出现并持续流动（dashoffset 动画）
  3. 25 颗铜柱受重力散落（弹跳缓动）
  4. 超声波波纹 + 掩膜板微振 + 铜柱自组织寻孔入位
  5. 吹气清理 + 右上角放大视图标注架桥风险
  6. 掩膜板上升，铜柱精准就位，完成提示
