Add 3D loose-leaf chronicle of human civilisation
A Three.js site presenting 20 world history milestones as double-sided loose-leaf pages, with three views: a leather binder with page-flip animation, a golden timeline, and a dotted globe with great-circle arcs. All textures (paper, leather, registration cards, and 18 hand-drawn sketches) are generated procedurally via Canvas 2D, so no external image assets are needed beyond the Earth map. Includes dev helper scripts for screenshots, ASCII previews, and headless verification.

# 人类文明里程碑 · 活页编年史
|
||||||
|
|
||||||
|
一个以 **Three.js** 为核心、艺术化呈现世界历史里程碑的三维网站。它以一只**活页本**为隐喻，把历史中里程碑式的人、事、物登记成一张张两面活页：正面是登记卡（编号 / 时间 / 地区 / 名称 / 描述），背面是程序化生成的"铅笔素描"。
|
||||||
|
|
||||||
|
## 三种视图
|
||||||
|
|
||||||
|
| 视图 | 内容 |
|
||||||
|
| --- | --- |
|
||||||
|
| **活页本** | 皮革封面 + 金属活页环 + 20 张双面活页，翻页动画、纸张弯曲、堆叠阴影 |
|
||||||
|
| **时间轴** | 20 张活页沿金色时间轴一字排开，选中卡片上浮并显示年代 |
|
||||||
|
| **地理** | 点阵地球 + 经纬网 + 事件标记 + 相邻事件间的金色大圆航线，缓慢自转 |
|
||||||
|
|
||||||
|
## 技术要点
|
||||||
|
|
||||||
|
- **Three.js**（ES 模块 + Vite）渲染全部三维内容，`OrbitControls` 供旋转/缩放。
|
||||||
|
- **程序化纹理**：纸张、皮革、活页孔、登记卡、素描全部由 Canvas 2D 即时生成，无需外部图片。
|
||||||
|
- **程序化素描**：18 种手绘风格速写（头骨、泥板、金字塔、人像、神庙、王冠、斗兽场、卷轴、骑士、帆船、地球仪、苹果、蒸汽机、自由钟、进化树、原子、和平鸽、火箭），带抖动线条与排线阴影，同一词条每次渲染结果确定一致。
|
||||||
|
- **双面活页**：正面用 `FrontSide`、背面用 `BackSide`（内容预先水平镜像），配合纸张柔性弯曲，翻页时自然显露背面素描。
|
||||||
|
- 数据（`src/data/entries.js`）包含 20 条真实历史里程碑，含经纬度与分类（人 / 事 / 物）。
|
||||||
|
|
||||||
|
## 运行
|
||||||
|
|
||||||
|
```bash
|
||||||
|
npm install
|
||||||
|
npm run dev # 开发服务器
|
||||||
|
npm run build # 生产构建（dist/）
|
||||||
|
npm run preview # 预览生产构建
|
||||||
|
```
|
||||||
|
|
||||||
|
## 操作
|
||||||
|
|
||||||
|
- **拖动** 旋转视角，**滚轮** 缩放
|
||||||
|
- **← →** 或底部按钮 翻页（翻面查看背面素描）
|
||||||
|
- 点击 活页 / 时间轴卡片 / 地球标记 选中词条
|
||||||
|
- 顶部按钮或按键 **1 / 2 / 3** 切换 活页本 / 时间轴 / 地理 视图
|
||||||
|
