C Specification

The XrFaceExpressionInfoFB structure describes the information to obtain facial expression.

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

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.

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

Description

Callers should request a time equal to the predicted display time for the rendered frame. The system will employ appropriate modeling to provide expressions for this time.
