vive focus How to Change Head Location

[h-shirakami 1]

How can I temporarily rotate and move the HMD camera by myself in VIU?

I wanted to rotate the HMD's camera when an event occurred, so I rotated the ViveCameraRig, but I couldn't get the correct results.

I referred to Teleport in Examples.
It rotates the x-axis after moving forward, which is not the intended result. I think the cause is the movement of the camera. How can I change the camera transform directly?

Do you mean you want to rotate camera root around HMD?

public static void RotateAroundHMD(Transform vrOrigin, Transform hmd, Quaternion rot)
{
    vrOrigin.position = rot * (vrOrigin.position - hmd.position) + hmd.position;
    vrOrigin.rotation = rot * vrOrigin.rotation;
}

public static void OnSomeRightTurnEventOcurred()
{
    // Turn right around Y axis for 45 degree
    RotateAroundHMD(vrOrigin, hmd, Quaternion.Euler(new Vector3(0f, 45f, 0f)));
}

Ah!
I see.

I'll give it a try.

Thank you
