		<h1>参数化缓冲几何体（[name]）</h1>

		<p class="desc">生成由参数表示其表面的几何体。</p>

		<h2>导入</h2>

		<p>
			[name] 是一个附加组件，必须显式导入。
			See [link:#manual/introduction/Installation Installation / Addons].
		</p>

		<code>
			import { ParametricGeometry } from 'three/addons/geometries/ParametricGeometry.js';
		</code>

		<h2>代码示例</h2>

		<code>
		const geometry = new THREE.ParametricGeometry( 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 — 该函数接收介于 0 和 1 之间的 [page:Float u] 轴和 [page:Float v] 轴值，并修改第三个 [page:Vector3] 参数。默认函数用于生成曲面。<br />
		slices — 用于参数函数的切片数量。默认值为 *8*。<br />
		stacks — 用于参数函数的堆栈数量。默认值为 *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。
		</p>
