<h2>代码示例</h2>
<code>const geometry = new THREE.CylinderGeometry( 5, 5, 20, 32 );
const material = new THREE.MeshBasicMaterial( {color: 0xffff00} );
const cylinder = new THREE.Mesh( geometry, material );
scene.add( cylinder );
</code>
<h2>Constructor</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。

<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。
