Make my room a AR akvarium

I am making some fish ARs and I like to see them swim around in my apartment. I havent done any area targets before, so I thought I’ll use vuforia but I dont know if that is necessary? Would it not be easier to just use a cube that finds itself in my room and have te fishes being limited to just swim there?

Or how would you do it?

To be honest I think Vuforia’s area target would be an overkill ! If I were you, I would instantiate my experience with ARFoundation’s plane detection (or Vuforia’s). I personally never used Vuforia’s area target for my projects, but I was not impressed by their area target demo.

would it be better to:

1 Just make a planes in my room

2 have the fish being programmed to not go beyond those walls
… and have it on some ’ random movement’

thanks
