I built RetroFX Sneaker Lab as an interactive ecommerce demo. Shoppers can rotate the sneaker, inspect it from different angles, and switch colorways in the browser.
The design challenge was making the viewer feel natural on a phone. A drag on the product should rotate the model while visitors can still scroll to the details. I built the experience with Three.js and designed the interaction around both gestures.
For an ecommerce implementation, I focus on the details that matter once the demo is live: model loading, responsive controls, reduced motion, keyboard access, and a fallback when WebGL is unavailable.
