HI guys , in the previous Instructional Material Design lesson we ve used an app named Hp Reveal for AR ( Augmented Reality ). By using this app you can see the objects with a 3d perspective or you can put any object on real things. It was a good experience to use such a future Technology .If you want to see how to use it or any question about AR just click the link and watch the video on my Youtube channel . I hope you enjoy it ! :)
