Members

Member Descriptions

type is the XrStructureType of this structure.
next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.
supportsFaceTracking is an XrBool32, indicating if current system is capable of receiving face tracking input.

Description

An application can inspect whether the system is capable of receiving face tracking input by extending the XrSystemProperties with XrSystemFaceTrackingPropertiesFB structure when calling xrGetSystemProperties.

If a runtime returns XR_FALSE for supportsFaceTracking, the runtime must return XR_ERROR_FEATURE_UNSUPPORTED from xrCreateFaceTrackerFB.

Valid Usage (Implicit)

The XR_FB_face_tracking extension must be enabled prior to using XrSystemFaceTrackingPropertiesFB
type must be XR_TYPE_SYSTEM_FACE_TRACKING_PROPERTIES_FB
next must be NULL or a valid pointer to the next structure in a structure chain
