|
|
|
||
|
|
<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 );

<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>
|
