There is no direction what method can always get the camera, how to say?
Do you want to know what direction the camera is facing?
direction of motion
What are you trying to achieve?
raycaster = new THREE.Raycaster( new THREE.Vector3(), new THREE.Vector3(), 0, 10 );

Now the controls is constantly changing, how do I get the direction of movement of the camera in this case
