		<h1>立方相机（[name]）</h1>


		<p class="desc">创建6个摄像机，并将它们所拍摄的场景渲染到[page:WebGLCubeRenderTarget]上。</p>

		<h2>代码示例</h2>

		<code>
		// Create cube render target
		var cubeRenderTarget = new THREE.WebGLCubeRenderTarget( 128, { format: THREE.RGBFormat, generateMipmaps: true, minFilter: THREE.LinearMipmapLinearFilter } );

		// Create cube camera
		var cubeCamera = new THREE.CubeCamera( 1, 100000, cubeRenderTarget );
		scene.add( cubeCamera );

		// Create car
		var chromeMaterial = new THREE.MeshLambertMaterial( { color: 0xffffff, envMap: cubeRenderTarget.texture } );
		var car = new Mesh( carGeometry, chromeMaterial );
		scene.add( car );

		// Update the render target cube
		car.setVisible( false );
		cubeCamera.position.copy( car.position );
		cubeCamera.update( renderer, scene );

		// Render the scene
		car.setVisible( true );
		renderer.render( scene, camera );
		</code>

		<h2>构造器</h2>


		<h3>[name]( [param:Number near], [param:Number far], [param:WebGLCubeRenderTarget renderTarget] )</h3>
		<p>

		near -- 近剪切面的距离<br />
		far -- 远剪切面的距离<br />
		renderTarget -- The destination cube render target.
		</p>
		<p>
			构造一个包含6个[page:PerspectiveCamera PerspectiveCameras]（透视摄像机）的立方摄像机，并将其拍摄的场景渲染到一个[page:WebGLCubeRenderTarget]上。

		</p>


		<h2>属性</h2>
		<p>共有属性请参见其基类[page:Object3D]。</p>

		<h3>[property:WebGLCubeRenderTarget renderTarget]</h3>
		<p>
			The destination cube render target.
		</p>

		<h2>方法</h2>
		<p>共有方法请参见其基类[page:Object3D]。</p>


		<h3>[method:null update]( [param:WebGLRenderer renderer], [param:Scene scene] )</h3>
		<p>
		renderer -- 当前的WebGL渲染器<br />
		scene -- 当前的场景
		</p>
		<p>
			这个方法用来更新[page:CubeCamera.renderTarget renderTarget]（渲染目标对象）。
		</p>

		<h3>[method:null clear]( [param:WebGLRenderer renderer], [param:Boolean color], [param:Boolean depth], [param:Boolean stencil] )</h3>
		<p>
			这个方法用来来清除[page:CubeCamera.renderTarget renderTarget]的颜色、深度和/或模板缓冲区。
			颜色缓冲区设置为渲染器当前的“清除”色。参数默认值均为*true*。

		</p>
