C Specification

The XrEventDataVisibilityMaskChangedKHR structure is defined as:

// Provided by XR_KHR_visibility_mask
typedef struct XrEventDataVisibilityMaskChangedKHR {
    XrStructureType            type;
    const void*                next;
    XrSession                  session;
    XrViewConfigurationType    viewConfigurationType;
    uint32_t                   viewIndex;
} XrEventDataVisibilityMaskChangedKHR;

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.

  • session is the XrSession for which the view mask has changed.

  • viewConfigurationType is the view configuration whose mask has changed.

  • viewIndex is the individual view within the view configuration to which the change refers.

Description

The XrEventDataVisibilityMaskChangedKHR structure is queued to indicate that a given visibility mask has changed. The application should respond to the event by calling xrGetVisibilityMaskKHR to retrieve the updated mask. This event is per-view, so if the masks for multiple views in a configuration change then multiple instances of this event will be queued for the application, one per view.
