Find out three objects represent the past-present-future memory. Then using AR technology to create these three objects.
This is the video of the 3d model.
It cost me a lot of time on building AR model. This is my first time to do 3D model. So it cost me a lot of time on learning how to use it. However, when I was formilar this app. It is kind of easy to do it. And I need to have patient to adjust the location of each part. Next time, I think I need to add more texture to every unite, in this case my object can become more real. But the how stuff is good.
