Adding Interaction
Including interactivity (user inputs) in your AR experiences, especially when using 3D models, is key to engaging your user and maximising immersion. 3D models themselves listen out for when a user taps on them, and will initiate an assigned action once this occurs.
Adding Interactivity to 3D Models
Simply select the 3D model in the scene and assign an on-tap action to it.
