		<h2>代码示例</h2>

		<code>
		var points = [];
		for ( var i = 0; i < 10; i ++ ) {
			points.push( new THREE.Vector2( Math.sin( i * 0.2 ) * 10 + 5, ( i - 5 ) * 2 ) );
		}
		var geometry = new THREE.LatheBufferGeometry( points );
		var material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
		var lathe = new THREE.Mesh( geometry, material );
		scene.add( lathe );
		</code>

		<h2>构造器</h2>

		<h3>[name]([param:Array points], [param:Integer segments], [param:Float phiStart], [param:Float phiLength])</h3>
		<p>
		points — 一个Vector2对象数组。每个点的X坐标必须大于0。<br />
		segments — 要生成的车削几何体圆周分段的数量，默认值是12。<br />
		phiStart — 以弧度表示的起始角度，默认值为0。<br />
		phiLength — 车削部分的弧度（0-2PI）范围，2PI将是一个完全闭合的、完整的车削几何体，小于2PI是部分的车削。默认值是2PI。
		</p>

				基于参数创建一个LatheGeometry。

		<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>
