		<h1>[name]</h1>

		<p class="desc">
		Class for loading a font in JSON format. Returns a [page:Font Font], which is an
		array of [page:Shape Shapes] representing the font.
		This uses the [page:FileLoader] internally for loading files. <br /><br />

		You can convert fonts online using [link:https://gero3.github.io/facetype.js/ facetype.js]
		</p>

		<h2>Code Example</h2>

		<code>
		const loader = new THREE.FontLoader();
		const font = loader.load(
			// resource URL
			'fonts/helvetiker_bold.typeface.json',

			// onLoad callback
			function ( font ) {
				// do something with the font
				scene.add( font );
			},

			// onProgress callback
			function ( xhr ) {
				console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
			},

			// onError callback
			function ( err ) {
				console.log( 'An error happened' );
			}
		);
		</code>
