网页三维开发，建立控制器并连接摄像机

cameraController = new CameraController(stage)

cameraController.camera = camera

// Set default control keys——设置默认控制键

cameraController.setDefaultBindings()

// Turn on camera collision detection——打开摄像机碰撞检测

cameraController.checkCollisions = true

// Set collision detection radius for camera——设置摄像机碰撞检测弧度

cameraController.collisionRadius = 20

// Aim camera at the cube primitive——把摄像机定位到原始立方体上

cameraController.lookAt(box.coords)

-private function onEnterFrame(e:Event):void {

// User input processing

cameraController.processInput()

// Scene calculating. Scene will be recalculated and all changes will be redrawed in camera.
