		<h1>[name]</h1>

		<p class="desc">
			A class for generating text as a single geometry. It is constructed by providing a string of text, and a hash of
			parameters consisting of a loaded [page:Font] and settings for the geometry's parent [page:ExtrudeGeometry].
			See the [page:Font], [page:FontLoader] and [page:Creating_Text] pages for additional details.

		<h2>Code Example</h2>

		<code>
		const loader = new THREE.FontLoader();

		loader.load( 'fonts/helvetiker_regular.typeface.json', function ( font ) {

			const geometry = new THREE.TextGeometry( 'Hello three.js!', {
				font: font,
				size: 80,
				height: 5,
				curveSegments: 12,
				bevelEnabled: true,
				bevelThickness: 10,
				bevelSize: 8,
				bevelOffset: 0,
				bevelSegments: 5
			} );
		} );
		</code>

		<h2>Constructor</h2>

		<h3>[name]([param:String text], [param:Object parameters])</h3>
		<p>
		text — The text that needs to be shown. <br />
		parameters — Object that can contains the following parameters.
		<ul>
			<li>font — an instance of THREE.Font.</li>
			<li>size — Float. Size of the text. Default is 100.</li>
			<li>height — Float. Thickness to extrude text.  Default is 50.</li>
			<li>curveSegments — Integer. Number of points on the curves. Default is 12.</li>
			<li>bevelEnabled — Boolean. Turn on bevel. Default is False.</li>
			<li>bevelThickness — Float. How deep into text bevel goes. Default is 10.</li>
			<li>bevelSize — Float. How far from text outline is bevel. Default is 8.</li>
			<li>bevelOffset — Float. How far from text outline bevel starts. Default is 0.</li>
			<li>bevelSegments — Integer. Number of bevel segments. Default is 3.</li>
		</ul>
		</p>

		<h2>Available Fonts</h2>

		<p>
		TextGeometry uses <a href='http://gero3.github.io/facetype.js/' target="_top">typeface.json</a> generated fonts.
		Some existing fonts can be found located in <b>/examples/fonts</b> and must be included in the page.
