使用three.js实现视频贴图可以让你在WebGL场景中显示视频。下面是一个简单的例子,展示如何在three.js中实现视频贴图:
首先,我们需要准备一个HTML5 video元素:
```html
<video id="video" width="320" height="240" src="video.mp4"></video>
```
接下来,我们需要创建一个THREE.VideoTexture对象,并将其与video元素关联起来:
```javascript
var video = document.getElementById( 'video' );
var texture = new THREE.VideoTexture( video );
texture.minFilter = THREE.LinearFilter;
texture.magFilter = THREE.LinearFilter;
texture.format = THREE.RGBFormat;
```
然后,我们可以将这个贴图应用到一个THREE.Mesh对象上:
```javascript
var geometry = new THREE.PlaneBufferGeometry( 2, 2 );
var material = new THREE.MeshBasicMaterial( { map: texture } );
var mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );
```
最后,我们需要在动画循环中更新视频贴图:
```javascript
function animate() {
requestAnimationFrame( animate );
if ( video.readyState === video.HAVE_ENOUGH_DATA ) {
texture.needsUpdate = true;
}
renderer.render( scene, camera );
}
animate();
```
这样,我们就可以在three.js中实现视频贴图了。
