Where do I get a GLB file of my product?↓
Either from a 3D artist or CAD source if one exists, from a self-serve image-to-3D tool if you're comfortable reviewing and fixing the output yourself, or from a managed service that generates and quality-checks the model from product photos for you, as Augmenta does.
Do I need a USDZ file too?↓
Only if you want AR on iPhone. Apple's Quick Look AR viewer requires USDZ; it will not open a GLB. Android's Scene Viewer and desktop/mobile browsers work directly with GLB, so USDZ is strictly an iOS AR addition, not a replacement.
Will embedding a 3D model slow down my site?↓
Not if it's set up correctly. Load the model lazily (only when it scrolls into view or on interaction), compress the GLB with Draco and compressed textures, and always show a poster image so the page has something to paint immediately. An unoptimized multi-tens-of-megabytes GLB loaded eagerly on every page view is what causes the slowdown people worry about, not 3D itself.
Can I embed a 3D model on Shopify or WordPress specifically?↓
Yes to both. Shopify has native 3D model support in the product Media field, no app needed for basic display. WordPress/WooCommerce needs either hand-written model-viewer markup or a plugin — the Augmenta AR plugin adds a shortcode, Gutenberg block, and Elementor widget for exactly this.
Can shoppers use AR without installing an app?↓
Yes. model-viewer's ar attribute triggers each platform's built-in AR viewer directly from the browser: Quick Look on iPhone and Scene Viewer on Android. No app download is required on either platform.
What's the actual minimum code to get a model on a page?↓
One script tag loading model-viewer from a CDN, and one model-viewer element with a src pointing at your GLB, ios-src pointing at your USDZ, plus the ar and camera-controls attributes. That's a working, rotatable, AR-capable embed.
