A-Frame VR WebXR

A-Frame is an open-source web framework for building 3D and immersive experiences. Built on Three.js, A-Frame lets you write VR/AR in HTML and JavaScript instead of dealing with raw WebGL. An contains elements that you compose with components (geometry, material, animation, physics). It's declarative, like HTML, but in 3D. A-Frame targets VR headsets (Meta Quest, HTC Vive via WebXR), mobile VR (Google Cardboard), and mobile AR (AR.js plugin). Experiences run in the browser — no app store needed.
