XR hit test and A-Frame

Hi there, I am a real beginner in the world of 3D programming, so my question may sound stupid :blush: Anyway I try to understand how the example: ar :: hit test really works as I’d like to “convert” this to an a-frame component. Unfortunately I am not sure where to start and if it’s feasible or not. I’d like to interact with this dino through touch gestures (starting an animation, or changing its size).
