Getting the `radius` for a hand joint

Call XRFrame.getJointPose() with an XRJointSpace and an XRReferenceSpace to get an XRJointPose object which provides the radius property.

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"); const radius = frame.getJointPose( indexFingerTipJoint, referenceSpace, ).radius; } } }
