C Specification

The XrSemanticLabelsSupportInfoFB structure is defined as:

// Provided by XR_FB_scene
typedef struct XrSemanticLabelsSupportInfoFB {
    XrStructureType                   type;
    const void*                       next;
    XrSemanticLabelsSupportFlagsFB    flags;
    const char*                       recognizedLabels;
} XrSemanticLabelsSupportInfoFB;

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.

  • flags is a bitmask of XrSemanticLabelsSupportFlagBitsFB that specifies additional behaviors.

  • recognizedLabels is a NULL terminated string that indicates a set of semantic labels recognized by the application. Each semantic label must be represented as a string and be separated by a comma without spaces. This field must include at least "OTHER" and must not be NULL.

Description

The XrSemanticLabelsSupportInfoFB structure may be specified in the next chain of XrSemanticLabelsFB to specify additional behaviors of the xrGetSpaceSemanticLabelsFB function. The runtime must follow the behaviors specified in flags according to the descriptions of XrSemanticLabelsSupportFlagBitsFB. The runtime must return any semantic label that is not included in recognizedLabels as "OTHER" to the application. The runtime must follow this direction only if the runtime reports the XrExtensionProperties::extensionVersion as 2 or greater, otherwise the runtime must ignore this as an unknown chained structure.

If the XrSemanticLabelsSupportInfoFB structure is not present in the next chain of XrSemanticLabelsFB, the runtime may return any semantic labels to the application.
