A 3D product viewer has to work even when the ideal demo conditions disappear.
I built ProductStage 3D as a starter for React and Next.js storefronts. It gives shoppers a way to rotate a product, compare variants, and discover details through hotspots.
How it works
A renderer agnostic core describes the variants and hotspots. A Three.js adapter handles rendering, and the React viewer connects those pieces to the storefront.
Designing for real storefronts
I accounted for keyboard use, reduced motion, loading and error states, and a fallback when WebGL is unavailable. On touch screens, the viewer also has to coexist with page scrolling.
The clip shows the product showcase in motion. The documentation covers the viewer and its configurable parts.
