		<h1>[name]</h1>

		<p class="desc">
			用于展示对象世界轴心对齐的包围盒的辅助对象.

			注意:要想能正常运行,目标对象必须包含 [page:Geometry] 或 [page:BufferGeometry] ,
			所以当目标对象是精灵 [page:Sprite Sprites] 时将不能正常运行.
		</p>

		<code>
		var sphere = new THREE.SphereGeometry();
		var object = new THREE.Mesh( sphere, new THREE.MeshBasicMaterial( 0xff0000 ) );
		var box = new THREE.BoxHelper( object, 0xffff00 );
		scene.add( box );
		</code>


		<h2>构造函数</h2>


		<h3>[name]( [param:Object3D object], [param:Color color] )</h3>
		<p>
		[page:Object3D object]  -- (可选的) 被展示世界轴心对齐的包围盒的对象.<br />
		[page:Color color] --  (可选的) 线框盒子的16进制颜色值. 默认为 0xffff00.<br /><br />

		创建一个新的线框盒子包围指定的对象. 内部使用 [page:Box3.setFromObject]
		方法来计算尺寸. 注意:此线框盒子将包围对象的所有子对象.
		</p>

		<h2>方法</h2>
		<p>请到基类 [page:LineSegments] 页面查看公共方法.</p>

		<h3>[method:null update]()</h3>
		<p>
			更新辅助对象的几何体，与目标对象尺寸
			保持一致, 包围目标对象所有子对象. 请查看 [page:Box3.setFromObject].
		</p>

		<h3>[method:BoxHelper setFromObject]( [param:Object3D object] )</h3>
		<p>
			[page:Object3D object] - 用于创建辅助对象的目标 [page:Object3D] 对象.<br /><br />

			更新指定对象的线框盒子.
