Quaternion.Lerp

static function Lerp (from : Quaternion, to : Quaternion, t : float) : Quaternion

Description

Interpolates from towards to by t and normalizes the result afterwards.

This is faster than Slerp but looks worse if the rotations are far apart.

JavaScripts

// Interpolates rotation between the rotations
// of from and to.
// (Choose from and to not to be the same as
// the object you attach this script to)

var from : Transform;
var to : Transform;
var speed = 0.1;
function Update () {
transform.rotation =
Quaternion.Lerp (from.rotation, to.rotation, Time.time * speed);
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
public Transform from;
public Transform to;
public float speed = 0.1F;
void Update() {
transform.rotation = Quaternion.Lerp(from.rotation, to.rotation, Time.time * speed);
}
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

public from as Transform

public to as Transform

public speed as single = 0.1F

def Update():
transform.rotation = Quaternion.Lerp(from.rotation, to.rotation, (Time.time * speed))
