|
||
## 安装
|
||
|
||
### NPM 安装（推荐）
|
||
|
||
```bash
|
||
npm install iflow-engine
|
||
```
|
||
|
||
### Yarn 安装
|
||
|
||
```bash
|
||
yarn add iflow-engine
|
||
```
|
||
|
||
### PNPM 安装
|
||
|
||
```bash
|
||
pnpm add iflow-engine
|
||
```
|
||
|
||
### CDN / 本地文件引入
|
||
|
||
如果不使用包管理器，可以直接下载 JS 文件引入：
|
||
|
||
```html
|
||
<script src="./lib/iflow-engine.umd.js"></script>
|
||
```
|
||
|
||
---
|
||
|
||
## 原生 HTML 使用
|
||
|
||
### 方式一：使用 NPM + 构建工具
|
||
|
||
```html
|
||
<!DOCTYPE html>
|
||
<html lang="zh-CN">
|
||
<head>
|
||
<meta charset="UTF-8">
|
||
<title>BIM Engine Demo</title>
|
||
<style>
|
||
* { margin: 0; padding: 0; box-sizing: border-box; }
|
||
html, body { width: 100%; height: 100%; overflow: hidden; }
|
||
#app { width: 100%; height: 100%; }
|
||
</style>
|
||
</head>
|
||
<body>
|
||
<div id="app"></div>
|
||
|
||
<script type="module">
|
||
import { BimEngine } from 'iflow-engine';
|
||
|
||
// 1. 创建引擎实例
|
||
const engine = new BimEngine('app', {
|
||
locale: 'zh-CN',
|
||
theme: 'light'
|
||
});
|
||
|
||
// 2. 初始化 3D 引擎
|
||
const success = engine.engine.initialize({
|
||
version: 'v2',
|
||
showStats: false,
|
||
showViewCube: true
|
||
});
|
||
|
||
if (success) {
|
||
// 3. 加载模型
|
||
engine.engine.loadModel('./model/your-model', {
|
||
position: [0, 0, 0],
|
||
rotation: [0, 0, 0],
|
||
scale: [1, 1, 1]
|
||
});
|
||
}
|
||
</script>
|
||
</body>
|
||
</html>
|
||
```
|
||
|
||
### 方式二：使用 UMD（无构建工具）
|
||
|
||
```html
|
||
<!DOCTYPE html>
|
||
<html lang="zh-CN">
|
||
<head>
|
||
<meta charset="UTF-8">
|
||
<title>BIM Engine Demo</title>
|
||
<!-- 引入 UMD 版本 -->
|
||
<script src="https://unpkg.com/iflow-engine/dist/iflow-engine.umd.js"></script>
|
||
<style>
|
||
* { margin: 0; padding: 0; box-sizing: border-box; }
|
||
html, body { width: 100%; height: 100%; overflow: hidden; }
|
||
#app { width: 100%; height: 100%; }
|
||
</style>
|
||
</head>
|
||
<body>
|
||
<div id="app"></div>
|
||
|
||
<script>
|
||
// 1. 创建引擎实例
|
||
const engine = new LyzBimEngineSDK.BimEngine('app', {
|
||
locale: 'zh-CN',
|
||
theme: 'light'
|
||
});
|
||
|
||
// 2. 初始化 3D 引擎
|
||
const success = engine.engine.initialize({
|
||
version: 'v2',
|
||
showStats: false,
|
||
showViewCube: true
|
||
});
|
||
|
||
if (success) {
|
||
// 3. 加载模型
|
||
engine.engine.loadModel('./model/your-model', {
|
||
position: [0, 0, 0],
|
||
rotation: [0, 0, 0],
|
||
scale: [1, 1, 1]
|
||
});
|
||
}
|
||
</script>
|
||
</body>
|
||
</html>
|
||
```
|
||
|
||
### 完整功能示例
|
||
|
||
```javascript
|
||
let engine = null;
|
||
|
||
// 初始化
|
||
function init() {
|
||
engine = new LyzBimEngineSDK.BimEngine('app', {
|
||
locale: 'zh-CN',
|
||
theme: 'light'
|
||
});
|
||
|
||
engine.engine.initialize({
|
||
version: 'v2',
|
||
showStats: false,
|
||
showViewCube: true
|
||
});
|
||
|
||
engine.engine.loadModel('./model/building');
|
||
}
|
||
|
||
// 回到主视角
|
||
function goHome() {
|
||
engine.engine.CameraGoHome();
|
||
}
|
||
|
||
// 激活测量功能
|
||
// mode: 'distance' | 'minDistance' | 'angle' | 'elevation' | 'volume' | 'laserDistance' | 'slope' | 'spaceVolume'
|
||
function activateMeasure(mode) {
|
||
engine.engine.activateMeasure(mode);
|
||
}
|
||
|
||
// 停用测量
|
||
function deactivateMeasure() {
|
||
engine.engine.deactivateMeasure();
|
||
}
|
||
|
||
// 切换主题
|
||
function setTheme(theme) {
|
||
engine.setTheme(theme); // 'light' | 'dark'
|
||
}
|
||
|
||
// 切换语言
|
||
function setLocale(locale) {
|
||
engine.setLocale(locale); // 'zh-CN' | 'en-US'
|
||
}
|
||
|
||
// 销毁
|
||
function destroy() {
|
||
engine.destroy();
|
||
}
|
||
|
||
window.onload = init;

### 4. 使用组件
|
||
|
||
```jsx
|
||
// App.jsx
|
||
import React, { useRef } from 'react';
|
||
import { BimViewer } from './components/BimViewer';
|
||
|
||
function App() {
|
||
const viewerRef = useRef(null);
|
||
|
||
const handleReady = (engine) => console.log('引擎已就绪', engine);
|
||
const handleError = (error) => console.error('引擎错误', error);
|
||
|
||
return (
|
||
<div style={{ width: '100vw', height: '100vh', position: 'relative' }}>
|
||
<BimViewer
|
||
ref={viewerRef}
|
||
modelUrl="./model/building"
|
||
modelOptions={{ position: [0, 0, 0] }}
|
||
locale="zh-CN"
|
||
theme="light"
|
||
onReady={handleReady}
|
||
onError={handleError}
|
||
/>
|
||
|
||
<div style={{ position: 'absolute', top: 20, left: 20, zIndex: 100 }}>
|
||
<button onClick={() => viewerRef.current?.goHome()}>主视角</button>
|
||
<button onClick={() => viewerRef.current?.activateMeasure('distance')}>距离测量</button>
|
||
<button onClick={() => viewerRef.current?.deactivateMeasure()}>停止测量</button>
|
||
</div>
|
||
</div>
|
||
);
|
||
}
|
||
|
||
export default App;
|
||
```

## 类型定义
|
||
|
||
### EngineOptions
|
||
|
||
```typescript
|
||
interface EngineOptions {
|
||
version?: 'v1' | 'v2'; // WebGL 版本，默认 'v2'
|
||
showStats?: boolean; // 是否显示性能统计，默认 false
|
||
showViewCube?: boolean; // 是否显示视图立方体，默认 true
|
||
}
|
||
```
|
||
|
||
### ModelLoadOptions
|
||
|
||
```typescript
|
||
interface ModelLoadOptions {
|
||
position?: [number, number, number]; // 位置，默认 [0, 0, 0]
|
||
rotation?: [number, number, number]; // 旋转（弧度），默认 [0, 0, 0]
|
||
scale?: [number, number, number]; // 缩放，默认 [1, 1, 1]
|
||
id?: string; // 模型 ID（可选）
|
||
}
|
||
```
|
||
|
||
### MeasureMode
|
||
|
||
```typescript
|
||
type MeasureMode =
|
||
| 'distance' // 距离测量
|
||
| 'minDistance' // 最小距离测量
|
||
| 'angle' // 角度测量
|
||
| 'elevation' // 标高测量
|
||
| 'volume' // 体积测量
|
||
| 'laserDistance' // 激光测距
|
||
| 'slope' // 坡度测量
|
||
| 'spaceVolume'; // 空间体积测量
|
||
```
|
||

|
||
|
||
## 注意事项
|
||
|
||
1. **容器尺寸**：确保容器元素有明确的宽度和高度
|
||
|
||
2. **销毁清理**：页面关闭或组件卸载前务必调用 `destroy()`
|
||
|
||
3. **浏览器兼容**：需要支持 WebGL 的现代浏览器

||
## 常见问题
|
||
|
||
### Q: 模型加载失败？
|
||
|
||
检查：
|
||
- 模型路径是否正确
|
||
- 网络请求是否正常（F12 查看 Network）
|
||
- 模型格式是否支持
|
||
|
||
### Q: 如何监听引擎事件？
|
||
|
||
```javascript
|
||
engine.on('modelLoaded', (data) => {
|
||
console.log('模型已加载', data);
|
||
});
|
||
```
