C Specification

The XrFoveationEyeTrackedStateMETA structure is defined as:

// Provided by XR_META_foveation_eye_tracked
typedef struct XrFoveationEyeTrackedStateMETA {
    XrStructureType                        type;
    void*                                  next;
    XrVector2f                             foveationCenter[XR_FOVEATION_CENTER_SIZE_META];
    XrFoveationEyeTrackedStateFlagsMETA    flags;
} XrFoveationEyeTrackedStateMETA;

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.

  • foveationCenter is the center of the foveal region defined in NDC space in the range of -1 to 1 for both eyes.

  • flags is a bitmask of XrFoveationEyeTrackedStateFlagBitsMETA which indicates various characteristics for current foveation state.

Description

XrFoveationEyeTrackedStateMETA must be provided when calling xrGetFoveationEyeTrackedStateMETA. The runtime must interpret XrFoveationEyeTrackedStateMETA without any additional structs in its next chain in order to query eye tracked foveation state, e.g. the center of the foveal region.
