TextureLoader

加载texture的一个类。 内部使用ImageLoader来加载文件。

例子

var texture = new THREE.TextureLoader().load( 'textures/land_ocean_ice_cloud_2048.jpg' ); 
// 立即使用纹理进行材质创建 
var material = new THREE.MeshBasicMaterial( { map: texture } );

geometry / cube

Example with Callbacks

// 初始化一个加载器 
var 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 
    var 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.' ); 
  } 
);

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this thread

构造函数

TextureLoader( manager : LoadingManager )

manager — 加载器使用的loadingManager,默认值为THREE.DefaultLoadingManager.

创建一个新的TextureLoader.

属性

# .crossOrigin : String

如果设置了,在开始加载前, 将为图片分配 crossOrigin 属性,其值为 crossOrigin, 默认为"anonymous"。

# .manager : LoadingManager

加载器正在使用的loadingManager,默认值为DefaultLoadingManager.

# .path : String

被加载文件的基本路径,请参考.setPath。默认值为undefined.

方法

# .load ( url : String, onLoad : Function, onProgress : Function, onError : Function ) : Texture

url — 文件的URL或者路径,也可以为 Data URI.
onLoad — 加载完成时将调用。回调参数为将要加载的texture.
onProgress — 将在加载过程中进行调用。参数为XMLHttpRequest实例,实例包含total和loaded字节。
onError — 在加载错误时被调用。

从给定的URL开始加载并将完全加载的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。

# .setCrossOrigin ( value : String ) : null

设置.crossOrigin的属性。

# .setPath ( path : String ) : FileLoader

设置加载文件的基本路径或URL。当加载同一目录中的许多模型,此方法将很有用。
