TIFWIW, and mods remove if need be, but a user on that other site claims the following:
"I can’t delve into details, but just imagine if instead of [the Monsters ride] merely having a moving object/animatronic, say it’s projection mapped on top of, rendered in real-time. To say it’s spectacular in person is an understatement, which is just one of the reasons why I’m honestly expecting the Monsters Ride to be among the best attractions in the world, if not taking that title outright.
The Potter ride should be equally wild too, and will also feature that tech, but not quite as pronounced. The knock your socks off feature is instead of just boarding a ride vehicle and departing the load platform, the room around your vehicle physically moves with it, with the vehicle you’re in only leaving it after a bit."
We have to wait two years...how will I survive?
