<h2>代码示例</h2>
|
||
|
||
<code>const geometry = new THREE.RingGeometry( 1, 5, 32 );
|
||
const material = new THREE.MeshBasicMaterial( { color: 0xffff00, side: THREE.DoubleSide } );
|
||
const mesh = new THREE.Mesh( geometry, material );
|
||
scene.add( mesh );
|
||
</code>

|
||
<h2>构造器</h2>
|
||
|
||
<h3>[name]([param:Float innerRadius], [param:Float outerRadius], [param:Integer thetaSegments], [param:Integer phiSegments], [param:Float thetaStart], [param:Float thetaLength])</h3>
|
||
<p>
|
||
innerRadius — 内部半径，默认值为0.5。 <br />
|
||
outerRadius — 外部半径，默认值为1。<br />
|
||
thetaSegments — 圆环的分段数。这个值越大，圆环就越圆。最小值为3，默认值为8。<br />
|
||
phiSegments — 最小值为1，默认值为8。<br />
|
||
thetaStart — 起始角度，默认值为0。<br />
|
||
thetaLength — 圆心角，默认值为Math.PI * 2。

||
<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。
