		<h2>代码示例</h2>

		<code>var geometry = new THREE.CylinderGeometry( 5, 5, 20, 32 );
		var material = new THREE.MeshBasicMaterial( {color: 0xffff00} );
		var cylinder = new THREE.Mesh( geometry, material );
		scene.add( cylinder );
		</code>

		<h2>构造器</h2>

		<h3>[name]([param:Float radiusTop], [param:Float radiusBottom], [param:Float height], [param:Integer radialSegments], [param:Integer heightSegments], [param:Boolean openEnded], [param:Float thetaStart], [param:Float thetaLength])</h3>
		<p>
				radiusTop — 圆柱的顶部半径，默认值是1。<br />
				radiusBottom — 圆柱的底部半径，默认值是1。<br />
				height — 圆柱的高度，默认值是1。<br />
				radialSegments —  圆柱侧面周围的分段数，默认为8。<br />
				heightSegments — 圆柱侧面沿着其高度的分段数，默认值为1。<br />
				openEnded — 一个Boolean值，指明该圆锥的底面是开放的还是封顶的。默认值为false，即其底面默认是封顶的。<br />
				thetaStart — 第一个分段的起始角度，默认为0。（three o'clock position）<br />
				thetaLength — 圆柱底面圆扇区的中心角，通常被称为“θ”（西塔）。默认值是2*Pi，这使其成为一个完整的圆柱。
		</p>

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