How To Smoothly Animate From One Camera Position To Another

Question

The Question is basically self explanatory. I have a scene with many cameras and I'd like to smoothly switch from one to another. I am not looking for a cross fade effect but more to a camera moving and rotating the view in order to reach the next camera point of view and so on. To this end I have tried the following code:

    firstCamera.transform.position.x = Mathf.Lerp(firstCamera.transform.position.x, nextCamer.transform.position.x,Time.deltaTime*smooth);
    firstCamera.transform.position.y = Mathf.Lerp(firstCamera.transform.position.y, nextCamera.transform.position.y,Time.deltaTime*smooth);
    firstCamera.transform.position.z = Mathf.Lerp(firstCamera.transform.position.z, nextCamera.transform.position.z,Time.deltaTime*smooth);

    firstCamera.transform.rotation.x = Mathf.Lerp(firstCamera.transform.rotation.x, nextCamera.transform.rotation.x,Time.deltaTime*smooth);
    firstCamera.transform.rotation.z = Mathf.Lerp(firstCamera.transform.rotation.z, nextCamera.transform.rotation.z,Time.deltaTime*smooth);
    firstCamera.transform.rotation.y = Mathf.Lerp(firstCamera.transform.rotation.y, nextCamera.transform.rotation.y,Time.deltaTime*smooth);

But the result is actually not that good.

Thank you all, I fixed it this way

 var pos:Vector3 = firstCamera.transform.position;
    var rot:Quaternion = firstCamera.transform.rotation;
    firstCamera.transform.position = Vector3.Lerp(pos, nextCamera.transform.position,Time.deltaTime*smooth);
    firstCamera.transform.rotation = Quaternion.Lerp(rot, nextCamera.transform.rotation,Time.deltaTime*smooth);

Answer 1

Consider using Quaternion.Lerp or Quaternion.Slerp instead of lerping the euler angles directly.

Answer 2

You need to save the original position/rotation of firstCamera. It seems to be using the current values.
