XRFrame: fillJointRadii() method
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The fillJointRadii()
method of the XRFrame
interface populates a Float32Array
with radii for a list of hand joint spaces and returns true
if successful for all spaces.
Syntax
js
fillJointRadii(jointSpaces, radii)
Parameters
jointSpaces
-
An array of
XRJointSpace
objects for which to obtain the radii. radii
-
A
Float32Array
that is populated with the radii of thejointSpaces
.
Return value
A boolean indicating if all of the spaces have a valid pose.
Exceptions
TypeError
-
Thrown if the length of
jointSpaces
is larger than the number of elements inradii
.
Examples
Obtaining radii for all joints of a hand
To efficiently get all radii for all 25 joints of each XRHand
, you can use the fillJointRadii()
method.
js
let radii1 = new Float32Array(25);
let radii2 = new Float32Array(25);
function onXRFrame(xrFrame, renderer) {
let hand1 = xrFrame.session.inputSources[0].hand;
xrFrame.fillJointRadii(hand1.values(), radii1);
let hand2 = xrFrame.session.inputSources[1].hand;
xrFrame.fillJointRadii(hand2.values(), radii2);
}
