-# AI Code Generation Prompts: Startup Website Clone
-**Tech Stack:** Vite + Vue 3 (Script Setup) + Tailwind CSS + Lucide Icons
+# Web3D 场景 SDK 使用说明
+
+本 SDK 用于在 Web 场景中快速完成三维展示与交互，核心能力包括：相机修改、灯光调参、环境贴图切换、按配置渲染热点、热点驱动抛出事件、模型热加载/热销毁/热替换，以及按部件切换材质。

-## 🟢 Step 0: Project Setup (Global System Prompt)
-*在开始编写具体页面前，先发送这条指令，建立全局的设计规范和技术栈。*
-
-**Prompt:**
-
-> **Role:** Senior Frontend Developer specializing in Pixel-Perfect UI cloning.
->
-> **Tech Stack Requirements:**
-> - **Framework:** Vue 3 (Composition API with `<script setup>`) + typescript.
-> - **Build Tool:** Vite.
-> - **Styling:** Tailwind CSS (Mobile-first approach).
-> - **Icons:** `lucide-vue-next` (You must use this library).
-> - **Language:** TypeScript.
->
-> **Design System (Strict Adherence):**
-> - **Visual Style:** Minimalist, "Vercel-like" aesthetic. High contrast, clean lines.
-> - **Typography:** Inter or system-ui. Headings must use `tracking-tight` (letter-spacing: -0.025em).
-> - **Colors:**
->   - Background: `#ffffff` (White).
->   - Surface/Card: `#ffffff` (White) with `border-gray-200`.
->   - Primary Text: `#0f172a` (Slate-900).
->   - Muted Text: `#64748b` (Slate-500).
->   - Accents: Black buttons, Light gray backgrounds (`bg-gray-50`) for secondary elements.
-> - **Borders & Radius:** Delicate borders (`border`, `border-gray-100`). Card radius is `rounded-xl` or `rounded-2xl`.
-> - **Shadows:** Very subtle `shadow-sm`, hover states use `shadow-md`.
->
-> **Instruction:** I will provide tasks to build 3 specific pages. You must replicate the layout, spacing, and Chinese copy exactly as described.
+## 功能概览
+- 相机控制：支持位置/目标点/FOV/远近裁剪的即时更新，带缓动动画。
+- 灯光调参：主光、辅光、环境光强度、颜色、方向、阴影开关与软硬度。
+- 环境贴图：HDRI 切换、曝光度、旋转（偏航/俯仰）、模糊度。
+- 热点系统：基于配置渲染热点 UI，可按 click/hover/focus 抛出事件。
+- 模型热更新：按 ID 进行加载、销毁、替换，支持队列并行与完成回调。
+- 材质切换：按部件或分组应用/还原材质，支持预设表与回滚。
+- 事件总线：统一事件接口，便于业务侧订阅热点/相机/模型状态。

+// 平滑过渡到指定视角
+sdk.camera.animateTo(
+  { position: [1.2, 1, 2.4], target: [0, 0.8, 0], fov: 50 },

-## 🔴 Step 3: Features Page (功能特性页)
-*复制此段生成功能着陆页组件。*
+## 灯光调参
+```ts
+// 更新主方向光
+sdk.lights.update('key', {
+  intensity: 1.5,
+  color: '#ffffff',
+  direction: [0.3, -1, 0.25],
+  castShadow: true,
+})
 
-**Prompt:**
-
-> **Task:** Create a **`FeaturesPage.vue`** component. Clone the "Features" design exactly.

->   - **Text:** Title (font-bold mt-4) + Description (text-sm text-gray-500 mt-2).
->   - **The Mockup Area (Must Have):** At the bottom of each card, create a visual placeholder.
->   - *Implementation:* A `div` with `bg-gray-50/50 mt-6 h-32 w-full rounded border border-dashed border-gray-200`. Put a small "skeleton" UI inside (e.g., a few gray bars representing code lines) to mimic the screenshots.
->
-> **3. Stats Bar:**
-> - Layout: Flex row, wide container.
-> - Items:
->   - "2x" (交付效率提升)
->   - "40%" (Bug 修复加速)

+sdk.lights.update('ambient', { intensity: 0.25 })
+```

-## 💡 Developer Tips (For You)
+## 环境贴图
+```ts
+await sdk.environment.setHDRI('/envs/showroom_2k.hdr', {
+  exposure: 1.1,
+  rotation: [0, 45, 0], // yaw/pitch/roll
+  blur: 0.2,
+})
+```
 
-1.  **Global Font Fix:** To get the crisp look from the screenshots, add this to your `index.css` or `style.css`:
-    ```css
-    body {
-      font-family: -apple-system, BlinkMacSystemFont, "Inter", "Segoe UI", Roboto, sans-serif;
-      -webkit-font-smoothing: antialiased;
-      -moz-osx-font-smoothing: grayscale;
-    }
-    ```
-2.  **Icon Installation:** Ensure you have the icons installed:
-    ```bash
-    npm install lucide-vue-next
-    ```
-3.  **Refining:** If the AI output looks "too loose", tell it: *"Reduce the border-radius to 12px and make the text colors sharper (slate-900 instead of gray-800)."*

+## 热点渲染与事件
+```ts
+const hotspots = [
+  {
+    id: 'engine',
+    position: [0.8, 0.6, -0.2],
+    icon: 'info',
+    label: '发动机舱',
+    event: 'show-engine',
+    payload: { part: 'engine' },
+  },
+  {
+    id: 'door',
+    position: [1.1, 0.9, 0.4],
+    icon: 'action',
+    label: '开启车门',
+    event: 'toggle-door',
+    payload: { side: 'left' },
+  },
+]
+
+sdk.hotspot.render(hotspots)
+
+sdk.hotspot.on('click', ({ id, payload }) => {
+  // 业务侧根据 id/payload 触发操作
+})
+
+sdk.hotspot.on('hover', ({ id, hovering }) => {
+  // hover 高亮或提示
+})
+```
+
+事件命名建议（可按需扩展）：
+- `hotspot:click`、`hotspot:hover`、`hotspot:focus`
+- `hotspot:rendered`（所有热点就绪）
+
+---
+
+## 模型热加载 / 热销毁 / 热替换
+```ts
+// 加载
+await sdk.model.load({ id: 'car', url: '/models/car.glb', draco: true })
+
+// 销毁
+await sdk.model.destroy('car')
+
+// 替换（内部自动销毁旧实例并加载新实例）
+await sdk.model.replace('car', { url: '/models/car-white.glb' })
+```
+
+可以通过 `sdk.model.on('loaded' | 'replaced' | 'destroyed', handler)` 监听模型状态。
+
+---
+
+## 材质切换
+```ts
+// 应用材质预设
+sdk.material.apply({
+  target: 'body',           // 部件或分组名称
+  material: 'paint/blue',   // 预设 Key
+})
+
+// 批量切换
+sdk.material.batch([
+  { target: 'wheel', material: 'rim/chrome' },
+  { target: 'glass', material: 'glass/clear' },
+])
+
+// 还原默认材质
+sdk.material.reset('body')
+```
+
+---
+
+## 推荐的配置结构
+```json
+{
+  "camera": { "position": [2.5, 1.6, 3.2], "target": [0, 0.8, 0], "fov": 45 },

+  ]
+}
+```
+

+
+## 事件清单（示例）
+- 相机：`camera:changed`
+- 热点：`hotspot:click`、`hotspot:hover`、`hotspot:rendered`
+- 模型：`model:loaded`、`model:replaced`、`model:destroyed`
+- 材质：`material:applied`、`material:reset`
+
+订阅方式：
+```ts
+sdk.on('hotspot:click', (evt) => console.log(evt))
+sdk.off('hotspot:click', handler) // 移除监听
+```
+
+---
+
+## 调试建议
+- 启用 `sdk.debug(true)` 查看加载、事件、帧率等日志。
+- 逐步应用配置：先确认相机与灯光，再添加环境贴图与热点，最后再做材质/模型热更新。
+- 热更新前后记录 ID/实例，避免重复销毁或遗漏解绑事件。

+# 引入方式与事件监听
+
+介绍两种集成方式（全局挂载 / 模块化 ESM），以及统一的事件监听方法。
+
+## 全局挂载（非模块化）
+1. 引入全局构建产物（替换为你的实际部署地址）：
+   ```html
+   <script src="https://sdk.zguiy.com/zt/assets/index.js"></script>
+   ```
+2. 获取实例并初始化：
+   ```js
+   const kernel = window.faceSDK?.kernel
+   if (!kernel) {
+     console.error('SDK 未加载')
+   } else {
+     kernel.init({
+       container: 'renderDom',           // 容器 ID（canvas）
+       modelUrlList: ['./model.glb'],    // 模型列表
+       env: { hdrPath: '/hdr/my.env' },  // 环境贴图等参数
+     })
+   }
+   ```
+
+## 模块化（ESM）
+1. 在 `<script type="module">` 中导入：
+   ```js
+   import { kernel } from 'https://sdk.zguiy.com/zt/assets/index.js' // 构建后路径自行替换
+   ```
+2. 初始化（与全局方式一致）：
+   ```js
+   kernel.init({
+     container: 'renderDom',
+     modelUrlList: ['./model.glb'],
+     env: { envPath: '/hdr/my.env' },
+   })
+   ```
+
+## 事件监听（两种方式通用）
+```js
+kernel.on('model:load:progress', (data) => console.log('模型加载进度', data))
+kernel.on('model:loaded', (data) => console.log('模型加载完成', data))
+kernel.on('model:click', (data) => console.log('模型点击', data))
+
+// 需要时可移除
+// kernel.off('model:loaded', handler)

+## 初始化 Viewer
+```ts
+import { createViewer } from 'your-web3d-sdk'
+
+const sdk = await createViewer({
+  container: '#viewer',
+  assetsBase: '/assets',
+  background: '#0f172a',
+})
+
+// 加载初始场景或模型
+await sdk.model.load({ id: 'scene', url: '/models/showroom.glb' })
+```
+
+## 基础生命周期
+1. 初始化 viewer：`createViewer({ container })`
+2. 加载模型或场景：`sdk.model.load(...)`
+3. 设置环境贴图/灯光：`sdk.environment.setHDRI(...)`、`sdk.lights.update(...)`
+4. 渲染热点：`sdk.hotspot.render(config.hotspots)`
+5. 订阅事件：`sdk.on('hotspot:click', handler)`
+6. 按需调用相机/材质/模型热更新 API
+
+## 调试建议
+- 启用 `sdk.debug(true)` 查看加载、事件、帧率等日志。
+- 逐步应用配置：先确认相机与灯光，再添加环境贴图与热点，最后再做材质/模型热更新。
+- 热更新前后记录 ID/实例，避免重复销毁或遗漏解绑事件。
