Class for loading a [page:Texture texture].
|
||
|
|
This uses the [page:ImageLoader] internally for loading files.

<h2>Code Example</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
const texture = new THREE.TextureLoader().load( 'textures/land_ocean_ice_cloud_2048.jpg' );
|
||
|
|
|
||
|
|
// immediately use the texture for material creation
|
||
|
|
const material = new THREE.MeshBasicMaterial( { map: texture } );
|
||
|
|
</code>
|
||
|
|
|
||
|
|
<h2>Code Example with Callbacks</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
// instantiate a loader
|
||
|
|
const loader = new THREE.TextureLoader();
|
||
|
|
|
||
|
|
// load a resource
|
||
|
|
loader.load(
|
||
|
|
// resource URL
|
||
|
|
'textures/land_ocean_ice_cloud_2048.jpg',
|
||
|
|
|
||
|
|
// onLoad callback
|
||
|
|
function ( texture ) {
|
||
|
|
// in this example we create the material when the texture is loaded
|
||
|
|
const material = new THREE.MeshBasicMaterial( {
|
||
|
|
map: texture
|
||
|
|
} );
|
||
|
|
},
|
||
|
|
|
||
|
|
// onProgress callback currently not supported
|
||
|
|
undefined,
|
||
|
|
|
||
|
|
// onError callback
|
||
|
|
function ( err ) {
|
||
|
|
console.error( 'An error happened.' );
|
||
|
|
}
|
||
|
|
);
|
||
|
|

Please note three.js r84 dropped support for TextureLoader progress events. For a TextureLoader that supports progress events, see [link:https://github.com/mrdoob/three.js/issues/10439#issuecomment-293260145 this thread].

<h2>Examples</h2>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
[example:webgl_geometry_cube geometry / cube]
|
||
|

</p>
|

|
|
<h2>Constructor</h2>
|
||
|
|
|
||
|
|
<h3>[name]( [param:LoadingManager manager] )</h3>
|
||
|
|
<p>
|
||
|
|
[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].<br /><br />
|
||
|
|
|
||
|
|
Creates a new [name].
|
||
|
|
</p>
|

|
<h2>Properties</h2>
|
||
|
|
<p>See the base [page:Loader] class for common properties.</p>
|
||
|
|
|
||
|
|
<h2>Methods</h2>
|
||
|
|
<p>See the base [page:Loader] class for common methods.</p>
|
||
|
|
|
||
|
|
<h3>[method:Texture load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
|
||
|
|
<p>
|
||
|
|
[page:String url] — the path or URL to the file. This can also be a
|
||
|
|
[link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].<br />
|
||
|
|
[page:Function onLoad] (optional) — Will be called when load completes. The argument will be the loaded [page:Texture texture].<br />
|
||
|
|
[page:Function onProgress] (optional) — This callback function is currently not supported.<br />
|
||
|
|
[page:Function onError] (optional) — Will be called when load errors.<br /><br />
|
||
|
|
|
||
|
|
Begin loading from the given URL and pass the fully loaded [page:Texture texture] to onLoad. The method also returns a new texture object which can directly be used for material creation.
|
||
|
|
If you do it this way, the texture may pop up in your scene once the respective loading process is finished.
