public static Quaternion Slerp (Quaternion a, Quaternion b, float t);


Spherically interpolates between a and b by t. The parameter t is clamped to the range [0, 1].

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