WebXROpenXR

WebXROpenXR is an interoperability framework designed to connect the WebXR API, which runs in web browsers, with the OpenXR runtime used by many native XR platforms. The aim is to let web-based virtual reality, augmented reality, and mixed reality experiences run on any device that supports OpenXR, without device- or platform-specific web integrations.

Technical approach: The project proposes an adapter layer that translates WebXR calls into OpenXR calls. This bridge can be deployed as a browser component, extension, or standalone runtime that hosts an OpenXR runtime and exposes a WebXR-compatible surface to the browser. During a session, the bridge handles pose tracking, input sources, rendering timing, and synchronization, translating events and data between the two APIs while maintaining web security and sandboxing. Rendering still occurs in the browser context, but the actual device drivers and sensor fusion may be executed by the OpenXR backend.

Development status and governance: WebXROpenXR is an emerging effort involving browser vendors, XR hardware makers, and standards bodies. It is experimental and not yet standardized across platforms; support is uneven and typically limited to test environments or specific builds. Community discussions focus on API mapping, feature parity, and performance optimizations.

Impact and usage: If standardized, WebXROpenXR would simplify cross-platform web XR development, reduce fragmentation, and broaden device compatibility for web apps. Potential drawbacks include added translation overhead, security considerations, and reliance on the OpenXR ecosystem.
