Before the keynote AR, there was the quiet 3D viewer, and it never left. Rotatable product viewers answer the question every online shopper asks: what does this actually look like. - The brands doing it well treat 3D as photography's smarter sibling, not a replacement. - Zoom into the stitching. Spin the bag. Check the back nobody photographed. - Load speed, honest materials, and mobile gestures that feel native. Shoppers will not fight your viewer; they will leave. - Start with hero products. Put 3D where shoppers hesitate most, measure, and let the winners fund the rollout. - Keep assets organized from the start. Future you will be grateful. - Capture got democratized: a seller phone-scan app for 3D assets turns your phone into a scanner. - And 3D is the on-ramp to AR: the same model powers the room preview. ModelSnap produces the 3D model and AR preview file, $4.99 per HD model.
