I have a second camera in my scene that I want to match the main camera FOV.
Vuforia sets the AR Camera FOV at runtime, so I need to update the second camera to match it once Vuforia changes it. The following code does not work:
void Start()
{
mainCamera = Camera.main;
var vuforia = VuforiaARController.Instance;
vuforia.RegisterVuforiaStartedCallback( OnVuforiaStarted );
}
private void OnVuforiaStarted()
{
if ( mainCamera != null )
{
GetComponentInChildren<Camera>().fieldOfView = mainCamera.fieldOfView;
}
}
(Code formatting not working)
If I wait a few additional frames, the mainCamera.fieldOfView does change to match my hardware. Is there any sort of callback/event I can listen to that gets fired when the FOV changes?
Thanks!
Thanks, I ended up going that route too. I didn't think about it, but since I support auto-rotation, I need to update the FOV every time the device is rotated. Probably more trouble than its worth to hook into all of those events, so update will suffice for now.
