C Specification
The xrCreateFacialTrackerHTC function is defined as
// Provided by XR_HTC_facial_tracking
XrResult xrCreateFacialTrackerHTC(
XrSession session,
const XrFacialTrackerCreateInfoHTC* createInfo,
XrFacialTrackerHTC* facialTracker);
Parameters
Description
An application can create an XrFacialTrackerHTC handle using xrCreateFacialTrackerHTC.
If the system does not support eye tracking or lip tracking, runtime must
return XR_ERROR_FEATURE_UNSUPPORTED
from
xrCreateFacialTrackerHTC according to the corresponding case.
In this case, the runtime must return XR_FALSE
for
XrSystemFacialTrackingPropertiesHTC::supportEyeFacialTracking
or
XrSystemFacialTrackingPropertiesHTC::supportLipFacialTracking
when the function xrGetSystemProperties is called, so that the
application may avoid creating a facial tracker.
