		<h1>边缘几何体（[name]）</h1>

		<p class="desc">这可以作为一个辅助对象来查看[page:BufferGeometry geometry]的边缘。</p>

		<h2>代码示例</h2>
		<code>
		const geometry = new THREE.BoxGeometry( 100, 100, 100 );
		const edges = new THREE.EdgesGeometry( geometry );
		const line = new THREE.LineSegments( edges, new THREE.LineBasicMaterial( { color: 0xffffff } ) );
		scene.add( line );
		</code>

		<h2>例子</h2>
		<p>
			[example:webgl_helpers helpers]
		</p>

		<h2>构造器</h2>

		<h3>[name]( [param:BufferGeometry geometry], [param:Integer thresholdAngle] )</h3>
		<p>
		geometry — 任何一个几何体对象。<br />
		thresholdAngle — 仅当相邻面的法线之间的角度（单位为角度）超过这个值时，才会渲染边缘。默认值为1。
		</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>
