XRPose class
Secure context: This feature is available only in secure
contexts (HTTPS), in some or all supporting browsers.
is a WebXR API interface representing a position and
orientation in the 3D space, relative to the XRSpace within
which it resides. The XRSpace—which is either an
XRReferenceSpace or an XRBoundedReferenceSpace—defines the
coordinate system used for the pose and, in the case of an
XRViewerPose, its underlying views.
To obtain the for the XRSpace used as the local coordinate
system of an object, call XRFrame.getPose(), specifying that
local XRSpace and the space to which you wish to convert:
thePose = xrFrame.getPose(localSpace, baseSpace);
The pose for a viewer (or camera) is represented by the
XRViewerPose subclass of . This is obtained using
XRFrame.getViewerPose() instead of getPose(), specifying a
reference space which has been adjusted to position and orient
the node to provide the desired viewing position and angle:
viewerPose = xrFrame.getViewerPose(adjReferenceSpace);
Here, adjReferenceSpace is a reference space which has been
updated using the base frame of reference for the frame and any
adjustments needed to position the viewer based on movement or
rotation which is being supplied from a source other than the XR
device, such as keyboard or mouse inputs.
See the article Movement, orientation, and motion for further
details and an example with thorough explanations of what's going
on.
