render hologram in tracking loss status
To render a hologram as head-locked, I was using the following code:
Transform cameraTransform = Camera.main.transform;
interpolator.SetTargetPosition(cameraTransform.position + (cameraTransform.forward * Distance));
interpolator.SetTargetRotation(Quaternion.LookRotation(-cameraTransform.forward, -cameraTransform.up));
But when we are in a tracking loss status, it seems that the "Camera.main.transform" variable will not be available to use. I understand there are some codes to determine we are in the tracking loss status as the following:
void Update()
{
switch (UnityEngine.VR.WSA.WorldManager.state)
{
case PositionalLocatorState.Active:
// handle active
break;
case PositionalLocatorState.Activating:
case PositionalLocatorState.Inhibited:
case PositionalLocatorState.OrientationOnly:
case PositionalLocatorState.Unavailable:
default:
// only rotational information is available
break;
}
}
But what should I do in the cases of tracking loss to render a hologram in front of me? Looking forward to your help!
