WebVR allows users to have immersive virtual reality experiences directly within web browsers. It provides frictionless access to VR across platforms and works with various VR headsets like Cardboard, Daydream, Oculus Rift, and Vive. The WebVR API is a W3C standard for enabling VR on the web and browser support is growing, with Chrome, Firefox, and others supporting it on Android and desktop. Developers can build WebVR experiences using frameworks like three.js and markup languages while tools and formats like OBJ/MTL files help create and deploy VR content on the web platform.
