		<h1>[name]</h1>

		<div class="desc">
		A loader for loading a <em>.gltf</em> resource in <em>JSON</em> format.
		<br /><br />
		The <a href="https://www.khronos.org/gltf">glTF file format</a> is a JSON file format to enable rapid delivery and loading of 3D content.
		</div>


		<h2>Constructor</h2>

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

		<h2>Properties</h2>


		<h2>Methods</h2>

		<h3>[method:null load]( [page:String url], [page:Function onLoad], [page:Function onProgress], [page:Function onError] )</h3>
		<div>
		[page:String url] — required<br />
		[page:Function onLoad] — Will be called when load completes. The argument will be the loaded JSON response returned from [page:Function parse].<br />
		[page:Function onProgress] — Will be called while load progresses. The argument will be the XMLHttpRequest instance, that contains .[page:Integer total] and .[page:Integer loaded] bytes.<br />
		[page:Function onError] — Will be called when load errors.<br />
		</div>
		<div>
		Begin loading from url and call the callback function with the parsed response content.
		</div>

		<h3>[method:null setPath]( [page:String path] )</h3>
		<div>
		[page:String path] — Base path for loading additional resources e.g. textures, GLSL shaders, .bin data.
		</div>
		<div>
		Set the base path for additional resources.
		</div>

		<h3>[method:null setCrossOrigin]( [page:String value] )</h3>
		<div>
		[page:String value] — The crossOrigin string to implement CORS for loading the url from a different domain that allows CORS.
		</div>

		<h3>[method:null parse]( [page:Object json], [page:Function callBack], [page:String path] )</h3>
		<div>
		[page:Object json] — <em>JSON</em> object to parse.<br />
		[page:Function callBack] — Will be called when parse completes.<br />
		[page:String path] — The base path from which to find subsequent glTF resources such as textures, GLSL shaders and .bin data files.<br />
		</div>
		<div>
		Parse a glTF-based <em>JSON</em> structure and fire [page:Function callback] when complete. The argument to [page:Function callback] will be an [page:object] that contains loaded parts: .[page:Scene scene], .[page:Array cameras], .[page:Array animations] and .[page:Array shaders]
		</div>


		<h2>Notes</h2>

		<div>
		When using custom shaders provided within a glTF file [page:THREE.GLTFLoader.Shaders] should be updated on each render loop. See [example:webgl_loader_gltf] demo source code for example usage.
		</div>

		<div>
		This class is often used with [page:THREE.GLTFLoader.Animations THREE.GLTFLoader.Animations] to animate parsed animations. See [example:webgl_loader_gltf] demo source code for example usage.
		</div>

		<h2>Example</h2>

		<code>
		// instantiate a loader
		var loader = new THREE.GLTFLoader();

		// load a glTF resource
		loader.load(
			// resource URL
			'models/gltf/duck/duck.json',
			// Function when resource is loaded
			function ( object ) {
				scene.add( object.scene );
			}
		);
		</code>
