		<h2>代码示例</h2>

		<code>const geometry = new THREE.TorusGeometry( 10, 3, 16, 100 );
		const material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
		const torus = new THREE.Mesh( geometry, material );
		scene.add( torus );
		</code>

		<h2>构造器</h2>

		<h3>[name]([param:Float radius], [param:Float tube], [param:Integer radialSegments], [param:Integer tubularSegments], [param:Float arc])</h3>
		<p>
				radius - 环面的半径，从环面的中心到管道横截面的中心。默认值是1。<br />
				tube — 管道的半径，默认值为0.4。<br />
				radialSegments — 管道横截面的分段数，默认值为12。<br />
				tubularSegments — 管道的分段数，默认值为48。<br />
				arc — 圆环的圆心角（单位是弧度），默认值为Math.PI * 2。
				</p>

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

		<h3>.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>
