The Hit-test API is an extension to the WebXR Device API that provides the capability of raycasting into the real world as understood by the underlying XR system. The goal is to provide a simple API that allows apps to place objects in the real world by casting rays that can be evaluated against the underlying platform's understanding of the real world geometry, regardless of how that is implemented (e.g., hit test against detected planes, point clouds, meshes, etc.).
