Creates 6 cameras that render to a [page:WebGLRenderTargetCube].

// Create cube camera
		var cubeCamera = new THREE.CubeCamera( 1, 100000, 128 );
		scene.add( cubeCamera );
		// Create car
		var chromeMaterial = new THREE.MeshLambertMaterial( { color: 0xffffff, envMap: cubeCamera.renderTarget.texture } );

		scene.add( car );

		// Render the scene
		car.setVisible( true );

		near -- The near clipping distance. 
		far -- The far clipping distance 
		cubeResolution -- Sets the length of the cube's edges. 
		options - (optional) object that holds texture parameters passed to the auto-generated WebGLRenderTargetCube.
		If not specified, the options default to:
		
		{ format: RGBFormat, magFilter: LinearFilter, minFilter: LinearFilter }
		
		
Constructs a CubeCamera that contains 6 [page:PerspectiveCamera PerspectiveCameras] that render to a [page:WebGLRenderTargetCube].
See the base [page:Object3D] class for common properties.
The cube texture that gets generated.
See the base [page:Object3D] class for common methods.
		renderer -- The current WebGL renderer 
		scene -- The current scene
		
Call this to update the [page:CubeCamera.renderTarget renderTarget].
Call this to clear the [page:CubeCamera.renderTarget renderTarget] color, depth, and/or stencil buffers. The color buffer is set to the renderer's current clear color. Arguments default to *true*.
