		<h1>[name]</h1>

		<p class="desc">
		用于模拟相机视锥体的辅助对象.<br />
		它使用 [page:LineSegments] 来模拟相机视锥体.
		</p>

		<h2>例子</h2>

		<div>[example:webgl_camera WebGL / camera]</div>
		<div>[example:webgl_geometry_extrude_splines WebGL / extrude / splines]</div>

		<code>
var camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );
var helper = new THREE.CameraHelper( camera );
scene.add( helper );
		</code>


		<h2>构造函数</h2>


		<h3>[name]( [param:Camera camera] )</h3>
		<p>
		[page:Camera camera] -- 被模拟的相机.<br /><br />

		为指定相机创建一个新的相机辅助对象 [Name] .
		</p>



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



		<h3>[property:Camera camera]</h3>
		<p>被模拟的相机.</p>

		<h3>[property:object pointMap]</h3>
		<p>包含用于模拟相机的点.</p>

		<h3>[property:object matrix]</h3>
		<p>请参考相机的世界矩阵 [page:Object3D.matrixWorld camera.matrixWorld].</p>

		<h3>[property:object matrixAutoUpdate]</h3>
		<p>
			请查看 [page:Object3D.matrixAutoUpdate]. 这里设置为 *false* 表示辅助对象
			使用相机的 [page:Object3D.matrixWorld matrixWorld].
		</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>基于相机的投影矩阵更新辅助对象.</p>
