Add Easing to Transform.Rotate

Hi,

I'm using a C# script to rotate an object based off a two finger rotate gesture. The following script works great, but I'd like to add a little easing to the rotation. I've tried implementing some easing equations, but can't get things to work.

I thought about trying to use Quaternion.Slerp, but I need angleThen and angleNow to be of type Quaternion and I'm not sure how to convert these values using Quaternion constructor.

transform.rotation = Quaternion.Slerp (angleThen, angleNow, Time.time * 0.4);

I'd greatly appreciate any help or advice!

Thanks,

Wes

float zDistanceFromCamera = Vector3.Distance(Camera.main.transform.position,transform.position); Vector3 screenPosition0 = new Vector3(touch0.position.x,touch0.position.y,zDistanceFromCamera); Vector3 lastScreenPosition0 = new Vector3(touch0.position.x - touch0.deltaPosition.x,touch0.position.y - touch0.deltaPosition.y,zDistanceFromCamera);

             Vector3 screenPosition1 = new Vector3(touch1.position.x,touch1.position.y,zDistanceFromCamera);
             Vector3 lastScreenPosition1 = new Vector3(touch1.position.x - touch1.deltaPosition.x,touch1.position.y - touch1.deltaPosition.y,zDistanceFromCamera);


             float angleNow = Mathf.Atan2(screenPosition0.x - screenPosition1.x, screenPosition0.y - screenPosition1.y) * Mathf.Rad2Deg;
             float angleThen = Mathf.Atan2(lastScreenPosition0.x - lastScreenPosition1.x, lastScreenPosition0.y - lastScreenPosition1.y) * Mathf.Rad2Deg;

             float angleDelta = (angleNow - angleThen);
             transform.Rotate(Vector3.up, angleDelta, Space.Self);
