<h2>代码示例</h2>
|
|
|
|
<code>const geometry = new THREE.TorusGeometry( 10, 3, 16, 100 );
|
|
const material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
|
|
const torus = new THREE.Mesh( geometry, material );
|
|
scene.add( torus );
|
|
</code>
|
|
|
|
<h2>构造器</h2>
|
|
|
|
<h3>[name]([param:Float radius], [param:Float tube], [param:Integer radialSegments], [param:Integer tubularSegments], [param:Float arc])</h3>
|
|
<p>
|
|
radius - 环面的半径，从环面的中心到管道横截面的中心。默认值是1。<br />
|
|
tube — 管道的半径，默认值为0.4。<br />
|
|
radialSegments — 管道横截面的分段数，默认值为8。<br />
|
|
tubularSegments — 管道的分段数，默认值为6。<br />
|
|
arc — 圆环的圆心角（单位是弧度），默认值为Math.PI * 2。

<h3>.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。
