C Specification

The XrFaceExpressionInfo2FB structure is defined as:

// Provided by XR_FB_face_tracking2
typedef struct XrFaceExpressionInfo2FB {
    XrStructureType    type;
    const void*        next;
    XrTime             time;
} XrFaceExpressionInfo2FB;

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.

  • time is an XrTime at which the facial expression weights are requested.

Description

The XrFaceExpressionInfo2FB structure describes the information to obtain facial expression. The application should pass a time equal to the predicted display time for the rendered frame. The system must employ appropriate modeling to provide expressions for this time.
