# three-is
在 typescript 使用 three.js 时的类型守卫
```ts
import {isOrthographicCamera, isPerspectiveCamera} from "three-is";
import * as THREE from "three";
const camera: THREE.PerspectiveCamera | THREE.OrthographicCamera = new THREE.OrthographicCamera()
if (isOrthographicCamera(camera)) {
// 为正交
} else if (isPerspectiveCamera(camera)) {
// 为透视
}
```
