Overview
- XR runtime environments abstract hardware complexity, enabling applications to run across different XR devices through standardized interfaces. OpenXR, the Khronos Group standard, provides vendor-neutral access to VR and AR platforms. WebXR enables browser-based XR experiences with Safari adding support in 2024. Runtimes manage tracking, input, and compositor services critical for immersive experiences.
