		<h1>圆环扭结几何体（[name]）</h1>

		<p class="desc">
			创建一个圆环扭结，其特殊形状由一对互质的整数，p和q所定义。如果p和q不互质，创建出来的几何体将是一个环面链接。</p>

		<h2>示例</h2>

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

		<h2>构造器</h2>

		<h3>[name]([param:Float radius], [param:Float tube], [param:Integer tubularSegments], [param:Integer radialSegments], [param:Integer p], [param:Integer q])</h3>
		<p>
			<ul>
				<li>radius - 圆环的半径，默认值为1。</li>
				<li>tube — 管道的半径，默认值为0.4。</li>
				<li>tubularSegments — 管道的分段数量，默认值为64。</li>
				<li>radialSegments — 横截面分段数量，默认值为8。</li>
				<li>p — 这个值决定了几何体将绕着其旋转对称轴旋转多少次，默认值是2。</li>
				<li>q — 这个值决定了几何体将绕着其内部圆环旋转多少次，默认值是3。</li>
			</ul>
		</p>

		<h2>属性</h2>

		<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>
