1. Environment Setup

Required Tools

Node.js (LTS)
Download from nodejs.org

Local Web Server

npm install -g http-server

https://aframe.io/releases/1.7.0/aframe.min.js

https://cdn.jsdelivr.net/gh/AR-js-org/AR.js@3.4.5/aframe/build/aframe-ar.js

Development Environment

HTTPS Certificate
Use mkcert or Let's Encrypt

Code Editor

2. Building Your First A-Frame Scene

HTML Boilerplate with A-Frame CDN

Scene Container: <a-scene> element

Adding Entities: <a-box>, <a-sphere>, <a-plane>

Lighting & Camera: light entity + camera look-controls

Assets Management: <a-assets> and glTF models

3. WebXR: Core Concepts

Session Types: VR, AR, Inline via navigator.xr.requestSession

Reference Spaces: local, bounded-floor, viewer

Anchors & Hit Testing for real-world object placement

Input Sources: controllers, hand-tracking, gaze

Rendering Loop: onXRFrame callback

4. Industry Applications & Innovation Ideas

🎮 Gaming
Browser-based multiplayer VR worlds

🛍️ Retail
3D try-on & AR overlays

🏠 Real Estate
Interactive virtual tours

🏥 Healthcare
Surgical simulation with haptics

🤝 Collaboration
Virtual offices with spatial audio

5. Educational Use Cases

🔬 Virtual Labs for safe STEM experiments

🏛️ Historical Reconstructions in VR

🗣️ Language Immersion environments

🌍 Remote Field Trips in immersive settings

📊 STEM Outreach with 3D coding visualizations

6. Future Trends in WebXR

📈 Standard Evolution: broader browser support
