Quaternion, How to rotate object slowly?

I use Unity 5.3.4 and Oculus VR and implement an application in VR envrionment.

I would like to rotate an object slowly using Quaternion. For example, when I turn my head 180 degrees to the right, the MainCamera turns around 90 degrees.

In Unity, tracked input of Oculus-VR is calculated automatically and return to Quaternion data. 

void Update()
{
    transform.localRotation = UnityEngine.VR.InputTracking.GetLocalRotation(UnityEngine.VR.VRNode.CenterEye);;
}

So I will rotate camera using this Quaternion. But I don't know how to rotate slowly.

I tried to calculate arithmetic operation, e.g. multiplication, division, to Quaternion. But it's not working

How to calculate Quaternion?

Solution

  • Just use:

    transform.localRotation =Quaternion.Lerp( transform.localRotation, UnityEngine.VR.InputTracking.GetLocalRotation(UnityEngine.VR.VRNode.CenterEye), Time.deltaTime);
