Unlike a 360° photo spin (a sequence of photographs), a true 3D viewer renders a real 3D model in the browser, so the shopper can rotate freely, zoom into detail and, with hotspots, read notes about materials and craftsmanship.
Modern viewers run on WebGL in any browser without plug-ins, and the same model can power augmented reality and configuration.
Why it matters
Inspection builds confidence. A shopper who can turn the product over and zoom in on the finish has fewer reasons to guess.
