		<h1>[name]</h1>

		<p class="desc">
		An exporter for `glTF` 2.0.
		<br /><br />
		[link:https://www.khronos.org/gltf glTF] (GL Transmission Format) is an
		[link:https://github.com/KhronosGroup/glTF/tree/master/specification/2.0 open format specification]
		for efficient delivery and loading of 3D content. Assets may be provided either in JSON (.gltf)
		or binary (.glb) format. External files store textures (.jpg, .png) and additional binary
		data (.bin). A glTF asset may deliver one or more scenes, including meshes, materials,
		textures, skins, skeletons, morph targets, animations, lights, and/or cameras.
		</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 { GLTFExporter } from 'three/addons/exporters/GLTFExporter.js';
		</code>

		<h2>Extensions</h2>

		<p>
			GLTFExporter supports the following
			[link:https://github.com/KhronosGroup/glTF/tree/master/extensions/ glTF 2.0 extensions]:
		</p>

		<ul>
			<li>KHR_lights_punctual</li>
			<li>KHR_materials_clearcoat</li>
			<li>KHR_materials_dispersion</li>
			<li>KHR_materials_emissive_strength</li>
			<li>KHR_materials_ior</li>
			<li>KHR_materials_iridescence</li>		
			<li>KHR_materials_specular</li>
			<li>KHR_materials_sheen</li>
			<li>KHR_materials_transmission</li>
			<li>KHR_materials_unlit</li>
			<li>KHR_materials_volume</li>
			<li>KHR_mesh_quantization</li>
			<li>KHR_texture_transform</li>
		</ul>

		<p>
			The following glTF 2.0 extension is supported by an external user plugin
		</p>

		<ul>
			<li>[link:https://github.com/takahirox/three-gltf-extensions KHR_materials_variants]</li>
		</ul>

		<h2>Code Example</h2>

		<code>
		// Instantiate a exporter
		const exporter = new GLTFExporter();

		// Parse the input and generate the glTF output
		exporter.parse(
			scene,
			// called when the gltf has been generated
			function ( gltf ) {

				console.log( gltf );
				downloadJSON( gltf );

			},
			// called when there is an error in the generation
			function ( error ) {

				console.log( 'An error happened' );

			},
			options
		);
		</code>

		<h2>Examples</h2>

		<p>
			[example:misc_exporter_gltf]
		</p>

		<h2>Constructor</h2>

		<h3>[name]()</h3>
		<p>
		</p>
		<p>
		Creates a new [name].
		</p>

		<h2>Methods</h2>

		<h3>[method:undefined parse]( [param:Object3D input], [param:Function onCompleted], [param:Function onError], [param:Object options] )</h3>

		<p>
		[page:Object input] — Scenes or objects to export. Valid options:<br />
		<ul>
			<li>
				Export scenes
				<code>
				exporter.parse( scene1, ... )
		exporter.parse( [ scene1, scene2 ], ... )
				</code>
			</li>
			<li>
				Export objects (It will create a new Scene to hold all the objects)
				<code>
				exporter.parse( object1, ... )
		exporter.parse( [ object1, object2 ], ... )
				</code>
			</li>
			<li>
				Mix scenes and objects (It will export the scenes as usual but it will create a new scene to hold all the single objects).
				<code>
				exporter.parse( [ scene1, object1, object2, scene2 ], ... )
				</code>
			</li>
		</ul>

		[page:Function onCompleted] — Will be called when the export completes. The argument will be the generated glTF JSON or binary ArrayBuffer.<br />
		[page:Function onError] — Will be called if there are any errors during the gltf generation.<br />
		[page:Options options] — Export options<br />
		<ul>
			<li>`trs` - bool. Export position, rotation and scale instead of matrix per node. Default is false</li>
			<li>`onlyVisible` - bool. Export only visible objects. Default is true.</li>
			<li>`binary` - bool. Export in binary (.glb) format, returning an ArrayBuffer. Default is false.</li>
			<li>`maxTextureSize` - int. Restricts the image maximum size (both width and height) to the given value. Default is Infinity.</li>
			<li>`animations` - Array<[page:AnimationClip AnimationClip]>. List of animations to be included in the export.</li>
			<li>`includeCustomExtensions` - bool. Export custom glTF extensions defined on an object's `userData.gltfExtensions` property. Default is false.</li>
		</ul>
		</p>
		<p>
		Generates a .gltf (JSON) or .glb (binary) output from the input (Scenes or Objects)
		</p>

		<h3>[method:Promise parseAsync]( [param:Object3D input], [param:Object options] )</h3>

		<p>
			Generates a .gltf (JSON) or .glb (binary) output from the input (Scenes or Objects).
		</p>
		<p>
			This is just like the [page:.parse]() method, but instead of
			accepting callbacks it returns a promise that resolves with the
			result, and otherwise accepts the same options.
		</p>
