"AR TOUR OCEAN" is an educational app which uses ARCore.

This app uses ARCore to display the living things in the sea in actual size with few steps.
You can observe giant fishes like whale sharks and tunas and moreover, small living things like gelly fishes and shrimps as if you are walking in the ocean.
Experts from Gakken, the major publisher of educational books in Japan, supervised the 3DCG to mimic the motion and the texture of the sea creatures.

You can also take snapshots with the sea creatures swimming in your house.
