I made a small AR experience over 5 hours in Unity using ARCore and my Android phone.
The experience allows users to place spheres on flat surfaces, and when the move towards the sphere it fades away to reveal a spinning cube, which speeds up the closer the user gets to it.
I created a short custom script to control the sphere fading and the cube spinning, this is by no means a ground breaking project but as all my AR work is bound up in NDAs I felt something should AR related should be in my portfolio
The app was made for AR capable devices an will need ARCore installed to work. I only use the rear camera for the experience.
You can find my script and the apk in my github repo here. You may need to install the latest version of ARCore from Google play and allow the app to be installed on your device to try it.
