3D Product Visualization

3D product visualization is the practice of presenting a product as an interactive 3D model that customers can rotate, zoom and inspect from every angle, instead of a set of fixed photos. Paired with Web AR, the same model can be placed in the customer’s real space at true scale. It is one of the more direct ways to reduce purchase uncertainty in online sales.

3D Scanning

3D scanning is the process of capturing the shape and surface of a real object or space as a digital 3D model. The main techniques are LiDAR (built into the iPhone Pro and iPad Pro), photogrammetry (3D from many overlapping photos) and structured light or laser scanning on dedicated hardware. For web 3D and Web AR, scanning is the practical alternative to modelling a product or building from scratch in Blender.

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.

Android XR

Android XR is Google’s operating system for XR headsets and glasses, built with Gemini AI and a Chromium browser at its core. It powers the Samsung Galaxy XR headset and will power the upcoming XREAL Aura glasses. It runs standard Android apps as well as XR-native ones, and its browser supports WebXR. That last point matters for the web: standards-based 3D and AR, including pages built with PausAR Viewer, work on Android XR devices.

Apple Quick Look

Apple Quick Look is the built-in AR preview on iOS, iPadOS and visionOS. It displays USDZ files as Augmented Reality in the real environment at true scale. Quick Look is supported system-wide in Safari, Mail, Messages and many third-party apps.

Apple Vision Pro

Apple Vision Pro is Apple’s spatial computing headset, running visionOS. It pairs high-resolution Micro-OLED displays with eye and hand tracking, so you navigate by looking and pinching, and high-quality passthrough blends the real room with digital content (Mixed Reality). The M5 refresh, released in October 2025, runs visionOS 26 and starts at 3,499 USD. For the web it matters that Safari on visionOS renders interactive 3D, supports WebXR and hands USDZ models to Apple Quick Look for spatial viewing.

ARCore

ARCore is Google’s augmented reality SDK for Android, the counterpart to Apple’s ARKit. It provides motion tracking, environmental understanding and light estimation, plus a Depth API that infers real-world depth from an ordinary camera and a Geospatial API that anchors content to real places worldwide. On the web, ARCore powers Google Scene Viewer, which displays GLB models in AR. Support depends on per-device certification, published by Google.

ARKit

ARKit is Apple’s augmented reality framework, introduced in 2017 for iOS and iPadOS and now also the spatial engine behind visionOS. It handles the hard parts of AR, motion tracking, surface and scene detection, light estimation and, on LiDAR devices, real-world depth, so apps and the system can place virtual objects convincingly in the real world. On the web you never call ARKit directly; it powers Apple Quick Look, which renders USDZ models in AR straight from Safari.

Augmented Reality (AR)

Augmented Reality (AR) overlays digital content onto a live view of the real world, usually through a smartphone camera. On the reality-virtuality continuum it sits close to the real end: the room stays visible and virtual objects are added on top, placed at real scale on your actual floor or desk. Unlike Virtual Reality, which replaces your surroundings, AR adds to them, and on modern phones it runs straight from the browser with no app install.

Blender

Blender is a free, open-source 3D creation suite for modeling, texturing, animation and rendering. Maintained by the Blender Foundation, it has become a default tool for preparing 3D assets for the web because it exports glTF and GLB natively, with full PBR materials. For most Web AR projects, Blender is where the model is cleaned up and exported before it ever reaches a website.
