A photo shows one angle that someone else chose. A 3D model lets the customer choose every angle themselves, which is exactly the control people want before they buy. For furniture, sanitary goods, machines and technical products, that difference shows up in fewer returns and higher conversion.
The natural next steps are a live 3D configurator for variants and Web AR for placing the product in the room. A real-world example: ALLAB uses 3D and AR in their WooCommerce shop to let customers preview framed art prints in their own space before checkout.
On WordPress, PausAR Viewer is the fastest route there. Upload a GLB (and a USDZ for iOS AR) into the Elementor widget, and the product becomes an interactive 3D viewer with an AR button, with no coding.
