<h1>平面几何体（[name]）</h1>
<p class="desc">一个用于生成平面几何体的类。</p>
<iframe id="scene" src="scenes/geometry-browser.html#PlaneGeometry"></iframe>
<script>
// iOS iframe auto-resize workaround
if ( /(iPad|iPhone|iPod)/g.test( navigator.userAgent ) ) {

<h2>示例</h2>
<code>var geometry = new THREE.PlaneGeometry( 5, 20, 32 );
var material = new THREE.MeshBasicMaterial( {color: 0xffff00, side: THREE.DoubleSide} );
var plane = new THREE.Mesh( geometry, material );
scene.add( plane );
</code>
<h2>构造器</h2>
<h3>[name]([param:Float width], [param:Float height], [param:Integer widthSegments], [param:Integer heightSegments])</h3>
<p>
width — 平面沿着X轴的宽度。默认值是1。<br />
height — 平面沿着Y轴的高度。默认值是1。<br />
widthSegments — （可选）平面的宽度分段数，默认值是1。<br />
heightSegments — （可选）平面的高度分段数，默认值是1。
</p>
<h2>属性</h2>
<p>共有属性请参见其基类[page:Geometry]。</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。
</p>
<h2>方法(Methods)</h2>
<p>共有方法请参见其基类[page:Geometry]。</p>
