		const x = 0, y = 0;

		const heartShape = new THREE.Shape();

		heartShape.moveTo( x + 5, y + 5 );
		heartShape.bezierCurveTo( x + 5, y + 5, x + 4, y, x, y );
		heartShape.bezierCurveTo( x - 6, y, x - 6, y + 7,x - 6, y + 7 );

		<h2>构造器</h2>


		<h3>[name]([param:Array shapes], [param:Integer curveSegments])</h3>
		<p>
		shapes — 一个单独的[page:Shape shape]，或者一个包含形状的[page:Array]。Default is a single triangle shape.<br />
		curveSegments - [page:Integer] - 每一个形状的分段数，默认值为12。
		</p>

		<h2>属性</h2>
		<p>共有属性请参见其基类[page:BufferGeometry]。</p>

		<h3>[property:Object parameters]</h3>
		<p>
				一个包含着构造函数中每个参数的对象。在对象实例化之后，对该属性的任何修改都不会改变这个几何体。
		</p>

		<h2>方法(Methods)</h2>
