Rotating Holograms

I want to rotate a hologram in x, y and z not just y direction like they have done in Holographic 211. Everytime I try to do it for X as well, it just doesnt work. Any suggestions @HoloSheep or anyone?

    Hi @nayanseth,
    If you want to allow for rotation along x, y, and z, then you'll need to add support for NavigationY and NavigationZ to GestureManager.cs, like so:

            NavigationRecognizer.SetRecognizableGestures(
            GestureSettings.Tap |
            GestureSettings.NavigationX |
            GestureSettings.NavigationY |
            GestureSettings.NavigationZ);

    If you're using similar scripts to the 211 course, you would then modify GestureAction.cs to respond to the user's hand movement in all directions. Here's a very rudimentary function that will rotate the model in x, y, and z:

        private void PerformRotation()
    {
        if (GestureManager.Instance.IsNavigating)
        {
            // If user is moving their hand left/right (Navigation_X), rotate along the Y axis
            float rotationFactor_Y = GestureManager.Instance.NavigationPosition.x * RotationSensitivity;

            // If user is moving their hand up or down (Navigation_Y), rotate along the X axis
            float rotationFactor_X = GestureManager.Instance.NavigationPosition.y * RotationSensitivity;

            // If user is moving their hand forward/backward (Navigation_Z), rotate along the Z axis
            float rotationFactor_Z = GestureManager.Instance.NavigationPosition.z * RotationSensitivity;

            // Apply rotation to object
            transform.Rotate(new Vector3(rotationFactor_X, -1 * rotationFactor_Y, rotationFactor_Z));
        }
    }

    For usability purposes, I would suggest locking at least one axis (Z), as rotating in all 3 directions can get confusing. You could also require the user to specify which axis to rotate around (either a button or voice command), so that only one rotation is applied per navigation gesture detected. This would give finer control to the user for rotating the object. You can also change the rotation speed by altering the RotationSensitivity value in the GestureAction script.

    I hope this helps,
    ~Angela

    Even if I add the GestureSettings.NavigationY | GestureSettings.NavigationZ , I am not getting any calls in method "NavigationRecognizer_NavigationUpdatedEvent" when I move the hand guesture towards up or down !
    Its still working for X axis.. but not for Y and Z.
    Can you please help me?

    I have exactly the same Problem. @shinoybabu did you found a solution?

    Stupid as I am, I made the Gestures Input with the Emulator wrong.
    Wrong: mouse right hold + move
    Correct: alt + mouse right hold + move

    @shinoybabu try that.
