Say, we have to enable stereo view for cardboard or others. Currently the native cardboard sdk for Unity does badly for tracking (ARkit bug, I think). There was so much drift and is not really usable. I'm not sure what the solution for this would be but I think it is necessary to have a solution for Stereo at least from ARKit's release so that it would better support Mixed reality use cases. I'm attaching @skdev3 's video for reference, it seems to do ok-ish for horizontal movements but vertical movements has got a lot of drift. It would be cool if someone comes up with a solution for this.
