<h2>代码示例</h2>
|
|
|
|
<code>const geometry = new THREE.TorusKnotGeometry( 10, 3, 100, 16 );
|
|
const material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
|
|
const torusKnot = new THREE.Mesh( geometry, material );
|
|
scene.add( torusKnot );
|
|
</code>

<h2>构造器</h2>
|
|
|
|
<h3>[name]([param:Float radius], [param:Float tube], [param:Integer tubularSegments], [param:Integer radialSegments], [param:Integer p], [param:Integer q])</h3>
|
|
<p>
|
|
<ul>
|
|
<li>radius - 圆环的半径，默认值为1。</li>
|
|
<li>tube — 管道的半径，默认值为0.4。</li>
|
|
<li>tubularSegments — 管道的分段数量，默认值为64。</li>
|
|
<li>radialSegments — 横截面分段数量，默认值为8。</li>
|
|
<li>p — 这个值决定了几何体将绕着其旋转对称轴旋转多少次，默认值是2。</li>
|
|
<li>q — 这个值决定了几何体将绕着其内部圆环旋转多少次，默认值是3。</li>
|
|
</ul>
|
|
</p>

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

|
|
|
<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。
