WebXRspecific

WebXRspecific is a term used to describe software components, modules, and patterns that are tailored to the WebXR APIs and to building XR experiences for the web. It is not a formal standard or specification, but a pragmatic label for code that relies on WebXR features.

WebXR provides a unified interface for accessing VR and AR devices from web applications. Core concepts include XRSession objects, immersive modes such as immersive-vr and immersive-ar, reference spaces, pose data, and input sources. WebXRspecific code typically manages the lifecycle of an XRSession, configures a rendering loop, and maps XR spaces to the application's scene.

Rendering and geometry: WebXR often works with WebGL or WebGPU. A common pattern is to drive the animation loop with session.requestAnimationFrame, update the scene using the viewer pose, and render with a viewer reference space. Additionally, developers use features like hit testing and anchors that are WebXR-specific to place content in the real world.

Input and interaction: WebXRspecific components process XRInputSource objects, track controllers, perform raycasting, and optionally provide haptic feedback. They must handle device availability, input events, and platform differences between browsers.

Libraries and tooling: Major web graphics libraries offer WebXR integration, such as Three.js (renderer.xr), Babylon.js, and A-Frame, which provide abstractions that simplify XR rendering and input handling while still exposing WebXR features.

Development considerations: Developers should perform feature detection (navigator.xr, isSessionSupported), require secure origins, handle permission prompts, provide non-XR fallbacks, and optimize performance to maintain smooth interactions on limited hardware.
