    Hello everyone!
    I have a question, please help and thanks!
    I want to know how to show the Angle information(degree) between AR camera and target object on a plane. (Using Smartphone)
    And I want to know how to "code" with Unity and AR Foundation.

    Thank again!

    AngleBetween(plane.normal, camera.forward)?
    This would be the 'opposite' angle of the one in your image (the angle between the 'up' for the plane, and the line in your image).
    The angle in your image would thus be (90 degrees - AngleBetween())
