- <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32。<br />
- phiSegments — 圆环半径的分段数字。最小值为1,默认值为1。<br />
- thetaStart — 起始角度,默认值为0。<br />
- thetaLength — 圆心角,默认值为Math.PI * 2。
- </p>
- <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。
