getWorldDirection( target ) {

		return super.getWorldDirection( target ).negate();

	}
Returns a vector representing the ("look") direction of the 3D object in world space.

This method is overwritten since cameras have a different forward vector compared to other
3D objects. A camera looks down its local, negative z-axis by default.

@param {Vector3} target - The target vector the result is stored to.
@return {Vector3} The 3D object's direction in world space.
