Setting Light.shadowCameraVisible to true triggers a warning message.This warning indicates that the property .shadowCameraVisible has been removed from THREE.Light. Instead, you should use new THREE.CameraHelper(light.shadow).
When attempting to add a new THREE.CameraHelper(Light.shadow) to the scene, an error is thrown.The error is as follows: Uncaught TypeError: this.camera.updateProjectionMatrix is not a function (three.js :35002)
To create a CameraHelper in Three.js, you need to provide a Camera object as an argument for the constructor:
var spotlight = new THREE.SpotLight( 0xFFAA55 );
spotlight.castShadow = true;
var cameraHelper = new THREE.CameraHelper( spotlight.shadow.camera );
scene.add( cameraHelper );
This code snippet is specific to Three.js version r107.
