Examples
Using XRJointSpace objects
You can use an XRJointSpace object and an XRReferenceSpace to get an XRJointPose by calling XRFrame.getJointPose().
js
navigator.xr
.requestSession({ optionalFeatures: ["hand-tracking"] })
.then(/** … */);
function renderFrame(session, frame) {
// …
for (const inputSource of session.inputSources) {
if (inputSource.hand) {
const indexFingerTipJoint = inputSource.hand.get("index-finger-tip"); // XRJointSpace
indexFingerTipJoint.jointName; // "index-finger-tip"
frame.getJointPose(indexFingerTipJoint, referenceSpace); // XRJointPose
}
}
}
