I've been working with a simple test app trying to manipulate a SceneView's camera. I am able to reposition, pan and tilt the camera using the position, heading and tilt properties. However I would also like to change the field of view of the camera's frustum. I see there is an fov property on the camera, but it appears to do nothing. I can assign values to this property and read them out again, but it seems to make no difference to the resulting view.
Is there a purpose to the fov property, or a specific use case that it is used for?
