Great tutorial, will use it as a base to start playing with this markerless approach, thanks for sharing. Although one flaw is that as it does not know about the surroundings if you open the app in a room/area with obstacles the ships fly through them. Might see how this works with the Structure Sensor

For a persistent model in the world you are going to need a fiducial marker for that. I would just use Vuforia for what you are trying to do. That way you can move around in the world and the 3d model will be stuck to wherever the marker is.

So, I am not exactly sure how to do this for cardboard and make it look good. You could try two textures 1 for each eye and just play with the orientation until it looks good, or maybe try added the google vr package to the scene and basically do the setup twice, once for each camera. You wouldn't need the gyro code in that case because google vr will take care of that part. Also, you wouldn't want an autotimer but rather cast a ray from the center of the screen and if the raycast hits a ship thats when you would shoot.

And suddenly you get a Plane after 3.29 minutes in the video and I don't really understand how and why?
