A time-gated interactive event platform built for Fourdesire's 2021 annual online gathering. The experience guided registered participants through a series of unlockable activities, from scanning a physical AR marker to reveal their exclusive character, to joining live sessions on Google Meet and Gather.Town. The platform tracked real-time attendance, enforced phase-based content unlocks tied to the event schedule, and concluded with a post-event survey that revealed a downloadable desktop wallpaper upon completion.
The AR character reveal was built as a standalone HTML page using A-Frame and AR.js with custom pattern marker detection. When the camera recognizes the physical marker included in the participant's physical kit, the corresponding character's animated 3D model (glTF/GLB format) is loaded and rendered directly over the marker in real time. Users can interact with the model via single-finger drag to rotate and two-finger pinch to scale, powered by custom A-Frame gesture components. A screenshot feature composites the live camera feed and the 3D scene into a single image using Canvas API and merge-images, which participants can save and share on Instagram with a pre-filled hashtag.
Achieving the final result required close, iterative collaboration with the 3D designer, experimenting with different export settings, polygon counts, texture formats, and animation baking to balance visual quality against mobile rendering performance within the WebAR environment.
