3D Viewer

A 3D viewer is a component that displays a 3D model in the browser so visitors can rotate, zoom and pan it in real time. It is the building block behind 3D product visualization and Web AR. Most web 3D viewers render with WebGL through libraries like Three.js, and many add an AR button that hands the model to the device's native AR.

A 3D viewer is the simplest, highest-impact piece of web 3D: just an interactive model the visitor can spin. No configurator logic, no AR yet, only the ability to look closely. For many product pages that alone is the upgrade that matters.

Under the hood, a viewer renders with WebGL, usually through Three.js or Google’s model-viewer, and loads a GLB file.

On WordPress, PausAR Viewer is exactly this, plus the optional AR step. Drop the Elementor widget in, upload a GLB, and you have a polished 3D viewer with camera controls and an optional Web AR button, with no coding. Examples of what that looks like in practice are on the PausAR Viewer demos page.

FAQ

What is the difference between a 3D viewer and a configurator?

A viewer lets you inspect one model. A 3D configurator adds variant switching on top. Start with a viewer, add a configurator when you have options to sell.

Which file format does a 3D viewer use?

GLB for web display, plus USDZ when you also want iOS AR.

How do I add a 3D viewer to WordPress?

Use the PausAR Viewer Elementor widget. Drag it into a page, upload a GLB, and you have an interactive 3D viewer with optional AR, no coding required.
