为了使vue-threejs的renderer能够根据屏幕自动刷新宽高,你可以使用Vue的生命周期函数来实现。具体步骤如下:
1.在Vue组件中引入VueThreejs和Three.js:
```javascript
import * as VueThreejs from 'vue-threejs'
import * as Three from 'three'
```
2.在Vue组件中定义renderer和camera:
```javascript
data() {
return {
renderer: null,
camera: null
}
},
mounted() {
// 创建renderer
this.renderer = new Three.WebGLRenderer({
antialias: true
})
// 创建camera
this.camera = new Three.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000)
},
```
3.在Vue组件中定义resize方法,用于在窗口大小改变时更新renderer的宽高:
```javascript
methods: {
resize() {
this.renderer.setSize(window.innerWidth, window.innerHeight)
this.camera.aspect = window.innerWidth / window.innerHeight
this.camera.updateProjectionMatrix()
}
},
```
4.在Vue组件中使用mounted和beforeDestroy生命周期函数来分别添加和移除resize事件监听器:
```javascript
mounted() {
// 创建renderer
this.renderer = new Three.WebGLRenderer({
antialias: true
})
// 创建camera
this.camera = new Three.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000)
// 添加resize事件监听器
window.addEventListener('resize', this.resize)
this.resize()
},
beforeDestroy() {
// 移除resize事件监听器
window.removeEventListener('resize', this.resize)
},
```
这样,当窗口大小改变时,resize方法会被调用,更新renderer的宽高,从而实现renderer根据屏幕自动刷新宽高。
