<h2>代码示例</h2>
|
|
|
|
<code>
|
|
const geometry = new THREE.ParametricGeometry( THREE.ParametricGeometries.klein, 25, 25 );
|
|
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
|
|
const klein = new THREE.Mesh( geometry, material );
|
|
scene.add( klein );
|
|
</code>

<h2>构造函数</h2>
|
|
|
|
|
|
<h3>[name]([param:Function func], [param:Integer slices], [param:Integer stacks])</h3>
|
|
<p>
|
|
func — A function that takes in a [page:Float u] and [page:Float v] value each between 0 and 1 and modifies a third [page:Vector3] argument. Default is a function that generates a curved plane surface.<br />
|
|
slices — The count of slices to use for the parametric function. Default is *8*.<br />
|
|
stacks — The count of stacks to use for the parametric function. Default is *8*.
|
|
</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。
