Aero Blocks (8th Wall version)
This is a mobile webapp that allows you to create simple structures using virtual wooden blocks in AR. Unlike WebXR which isn't supported on iPhone, this version uses 8th Wall which works on both iPhone and Android. No app download is required - it works within the browser.
You tap to create a ground plane which you can move, rotate or scale with two finger gestures. On top of the ground plane you can place different types of blocks and choose from five different colours. The model can be pushed below the ground plane in situations where the model is too high. The app has an undo system and the model can be saved locally on the device.
I have used this project to learn different AR platforms. I've also created versions for iOS, Unity and WebXR.
