XRAnchor
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The XRAnchor interface creates anchors which keep track of the pose that is fixed relative to the real world. With anchors, you can specify poses in the world that need to be updated to correctly reflect the evolving understanding of the world, such that the poses remain aligned with the same place in the physical world. That helps to build an illusion that the placed objects are really present in the user's environment.
Properties
XRAnchor.anchorSpaceRead only-
Returns an
XRSpaceobject to locate the anchor relative to otherXRSpaceobjects.
Methods
XRAnchor.delete()-
Removes the anchor.
Examples
Requesting a session with anchors enabled
navigator.xr.requestSession("immersive-ar", {
requireFeatures: ["anchors"],
}
Adding anchors
You can use XRFrame.createAnchor() to create an anchor.
frame.createAnchor(anchorPose, referenceSpace).then((anchor) => {
// Do stuff with the anchor (assign objects that will be relative to this anchor)
}, (error) => {
console.error("Could not create anchor: "" + error);
});
