C Specification

The XrSystemFacialSimulationPropertiesBD structure is defined as:

// Provided by XR_BD_facial_simulation
typedef struct XrSystemFacialSimulationPropertiesBD {
    XrStructureType    type;
    void*              next;
    XrBool32           supportsFaceTracking;
} XrSystemFacialSimulationPropertiesBD;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain.

  • supportsFaceTracking is an XrBool32, indicating if the current system is capable of receiving face tracking input.

Description

An application can inspect whether the system is capable of providing face tracking input by extending the XrSystemProperties::next chain with an XrSystemFacialSimulationPropertiesBD structure when calling xrGetSystemProperties.

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