		<h1>[name]</h1>

		<p class="desc">
			This helps with visualizing what a camera contains in its frustum. It
			visualizes the frustum of a camera using a [page:LineSegments].<br /><br />
			[name] must be a child of the scene.
		</p>

		<h2>Code Example</h2>
		<code>
const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );
const helper = new THREE.CameraHelper( camera );
scene.add( helper );
		</code>

		<h2>Examples</h2>
		<p>
			[example:webgl_camera WebGL / camera]<br />
			[example:webgl_geometry_extrude_splines WebGL / extrude / splines]
		</p>

		<h2>Constructor</h2>
		<h3>[name]( [param:Camera camera] )</h3>
		<p>
			[page:Camera camera] -- The camera to visualize.<br /><br />

			This create a new [Name] for the specified camera.
		</p>

		<h2>Properties</h2>
		<p>See the base [page:LineSegments] class for common properties.</p>

		<h3>[property:Camera camera]</h3>
		<p>The camera being visualized.</p>

		<h3>[property:Object pointMap]</h3>
		<p>This contains the points used to visualize the camera.</p>

		<h3>[property:Object matrix]</h3>
		<p>Reference to the [page:Object3D.matrixWorld camera.matrixWorld].</p>

		<h3>[property:Object matrixAutoUpdate]</h3>
		<p>
			See [page:Object3D.matrixAutoUpdate]. Set to `false` here as the helper is
			using the camera's [page:Object3D.matrixWorld matrixWorld].
		</p>

		<h2>Methods</h2>
		<p>See the base [page:LineSegments] class for common methods.</p>

		<h3>[method:undefined dispose]()</h3>
		<p>
			Frees the GPU-related resources allocated by this instance. Call this
			method whenever this instance is no longer used in your app.
		</p>

		<h3>
			[method:this setColors]( [param:Color frustum], [param:Color cone], [param:Color up], [param:Color target], [param:Color cross] )
		</h3>
		<p>Defines the colors of the helper.</p>

		<h3>[method:undefined update]()</h3>
		<p>Updates the helper based on the projectionMatrix of the camera.</p>
