XRJointPose: radius property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The read-only radius
property of the XRJointPose
interface indicates the radius (distance from skin) for a joint.
Value
A number indicating the radius in meters.
Examples
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.
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");
const radius = frame.getJointPose(
indexFingerTipJoint,
referenceSpace,
).radius;
