What is WebXR?
What is WebXR?
WebXR is a web-based API that enables the development of Virtual Reality (VR) and Augmented Reality (AR) experiences directly in a web browser. It provides a standardized framework for accessing XR (Extended Reality) devices, allowing developers to create immersive applications that run seamlessly across different headsets, AR glasses, and mobile devices—without requiring users to install standalone applications
How WebXR Works?
How WebXR Works?
WebXR replaces the older WebVR API and expands its capabilities to support Augmented Reality (AR) in addition to VR. It allows web applications to detect connected XR hardware and render immersive 3D content using JavaScript, HTML, and WebGL/WebGPU.
Developers use WebXR Device API to:
Detect XR Devices: Identify if a user’s system has a VR/AR headset or compatible hardware.
Render 3D Scenes in XR: Use WebGL, Three.js, Babylon.js, or A-Frame to create immersive environments.
Handle User Input: Track hand controllers, gestures, and motion inputs from devices like Oculus Quest, HTC Vive, and Microsoft HoloLens.
Manage AR Overlays: Blend digital content into the real world using AR-supported devices.
WebXR vs. Traditional VR Development?
WebXR vs. Traditional VR Development?
Unlike traditional VR development, which often relies on Unity, Unreal Engine, or proprietary SDKs, WebXR allows developers to create and deploy VR/AR experiences on the web, making them accessible across multiple platforms without requiring app installations.

WebXR Frameworks & Tools
Three.js – A JavaScript library for 3D rendering with WebGL.
A-Frame – A higher-level declarative framework for building VR/AR scenes with HTML.
Babylon.js – A powerful 3D engine with built-in WebXR support.
PlayCanvas – A WebGL game engine that supports WebXR.
Example: Basic WebXR VR Scene Using A-Frame
