Declaration

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

Parameters

a Start unit quaternion value, returned when t = 0.
b End unit quaternion value, returned when t = 1.
t Interpolation ratio. The value is clamped to the range [0, 1].

Returns

Quaternion A unit quaternion interpolated between quaternions a and b.

Description

Interpolates between a and b by t and normalizes the result afterwards.

This is faster than Slerp but the angular velocity will not be constant if the rotations are far apart.

// 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)

using UnityEngine;

public class Example : MonoBehaviour { Transform from; Transform to; float speed = 0.01f; float timeCount = 0.0f;

void Update() { transform.rotation = Quaternion.Lerp(from.rotation, to.rotation, timeCount * speed); timeCount = timeCount + Time.deltaTime; } }
