[page:Loader] &rarr;
<h1>[name]</h1>
<p class="desc">
加载[page:Texture texture]的一个类。
内部使用[page:ImageLoader]来加载文件。
</p>
<h2>代码示例</h2>
<code>
const texture = new THREE.TextureLoader().load( 'textures/land_ocean_ice_cloud_2048.jpg' );
// 立即使用纹理进行材质创建
const material = new THREE.MeshBasicMaterial( { map: texture } );
</code>
<h2>Code Example with Callbacks</h2>
<code>
// 初始化一个加载器
const loader = new THREE.TextureLoader();
// 加载一个资源
loader.load(
// 资源URL
'textures/land_ocean_ice_cloud_2048.jpg',
// onLoad回调
function ( texture ) {
// in this example we create the material when the texture is loaded
const material = new THREE.MeshBasicMaterial( {
map: texture
} );
},
// 目前暂不支持onProgress的回调
undefined,
// onError回调
function ( err ) {
console.error( 'An error happened.' );
}
);
</code>
<p>
请注意three.js r84遗弃了TextureLoader进度事件。对于支持进度事件的TextureLoader
请参考[link:https://github.com/mrdoob/three.js/issues/10439#issuecomment-293260145 this thread]。

<h2>例子</h2>
<p>
[example:webgl_geometry_cube geometry / cube]
</p>
<h2>构造函数</h2>
<h3>[name]( [param:LoadingManager manager] )</h3>
<p>
[page:LoadingManager manager] — 加载器使用的[page:LoadingManager loadingManager],默认值为[page:LoadingManager THREE.DefaultLoadingManager].<br /><br />
创建一个新的[name].
</p>
<h2>属性</h2>
<p>共有属性请参见其基类[page:Loader]。</p>
<h2>方法</h2>
<p>共有方法请参见其基类[page:Loader]。</p>
<h3>[method:Texture load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
<p>
[page:String url] — 文件的URL或者路径也可以为
[link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].<br />
[page:Function onLoad] — 加载完成时将调用。回调参数为将要加载的[page:Texture texture].<br />
[page:Function onProgress] — 将在加载过程中进行调用。参数为XMLHttpRequest实例实例包含[page:Integer total]和[page:Integer loaded]字节。<br />
[page:Function onError] — 在加载错误时被调用。<br /><br />
从给定的URL开始加载并将完全加载的[page:Texture texture]传递给onLoad。该方法还返回一个新的纹理对象该纹理对象可以直接用于材质创建。
如果采用此方法,一旦相应的加载过程完成,纹理可能会在场景中出现。
