		<h1>[name]</h1>

		<p class="desc">A loader for loading a `.obj` resource.<br />
		The [link:https://en.wikipedia.org/wiki/Wavefront_.obj_file OBJ file format] is a simple data-format
		that represents 3D geometry in a human readable format as the position of each vertex, the UV position of
		each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of
		vertices, and texture vertices.
		</p>

		<h2>Import</h2>

		<p>
			[name] is an add-on, and must be imported explicitly.
			See [link:#manual/introduction/Installation Installation / Addons].
		</p>

		<code>
			import { OBJLoader } from 'three/addons/loaders/OBJLoader.js';
		</code>

		<h2>Code Example</h2>

		<code>
		// instantiate a loader
		const loader = new OBJLoader();

		// load a resource
		loader.load(
			// resource URL
			'models/monster.obj',
			// called when resource is loaded
			function ( object ) {

				scene.add( object );

			},
			// called when loading is in progresses
			function ( xhr ) {

				console.log( ( xhr.loaded / xhr.total * 100 ) + '% loaded' );

			},
			// called when loading has errors
			function ( error ) {

				console.log( 'An error happened' );

			}
		);
		</code>

		<h2>Examples</h2>

		</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].
		</p>
		<p>
		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:undefined load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
		<p>
		[page:String url] — A string containing the path/URL of the `.obj` file.<br />
		[page:Function onLoad] — (optional) A function to be called after the loading is successfully completed. The function receives the loaded [page:Object3D] as an argument.<br />
		[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The function receives a XMLHttpRequest instance, which contains [page:Integer total] and [page:Integer loaded] bytes. If the server does not set the Content-Length header; .[page:Integer total] will be 0.<br />
		[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives error as an argument.<br />
		</p>
		<p>
		Begin loading from url and call onLoad with the parsed response content.
		</p>

		<h3>[method:Object3D parse]( [param:String text] )</h3>
		<p>
		[page:String text] — The textual `obj` structure to parse.
		</p>
		<p>
		Returns an [page:Object3D]. It contains the parsed meshes as [page:Mesh] and lines as [page:LineSegments].<br />
		All geometry is created as [page:BufferGeometry]. Default materials are created as [page:MeshPhongMaterial].<br />
		If an `obj` object or group uses multiple materials while declaring faces, geometry groups and an array of materials are used.
		</p>

		<h3>[method:this setMaterials]( [param:MTLLoader.MaterialCreator materials] )</h3>
		<p>
		[page:MTLLoaderMaterialCreator MTLLoader.MaterialCreator materials] - A MaterialCreator instance.
		</p>
		<p>
		Sets materials loaded by MTLLoader or any other supplier of a [page:MTLLoaderMaterialCreator MTLLoader.MaterialCreator].
		</p>
