C Specification

The XrSpatialComponentPlaneSemanticLabelListEXT structure is defined as:

// Provided by XR_EXT_spatial_plane_tracking
typedef struct XrSpatialComponentPlaneSemanticLabelListEXT {
    XrStructureType                    type;
    void*                              next;
    uint32_t                           semanticLabelCount;
    XrSpatialPlaneSemanticLabelEXT*    semanticLabels;
} XrSpatialComponentPlaneSemanticLabelListEXT;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain.

  • semanticLabelCount is a uint32_t describing the count of elements in the semanticLabels array.

  • semanticLabels is an array of XrSpatialPlaneSemanticLabelEXT.

Description

To query the plane semantic label component of the spatial entities in an XrSpatialSnapshotEXT, include XR_SPATIAL_COMPONENT_TYPE_PLANE_SEMANTIC_LABEL_EXT in XrSpatialComponentDataQueryConditionEXT::componentTypes and add XrSpatialComponentPlaneSemanticLabelListEXT to the XrSpatialComponentDataQueryResultEXT::next chain.

The runtime must return XR_ERROR_VALIDATION_FAILURE from xrQuerySpatialComponentDataEXT if XrSpatialComponentPlaneSemanticLabelListEXT is in the next chain of XrSpatialComponentDataQueryResultEXT::next but XR_SPATIAL_COMPONENT_TYPE_PLANE_SEMANTIC_LABEL_EXT is not included in XrSpatialComponentDataQueryConditionEXT::componentTypes.

The runtime must return XR_ERROR_SIZE_INSUFFICIENT from xrQuerySpatialComponentDataEXT if semanticLabelCount is less than XrSpatialComponentDataQueryResultEXT::entityIdCountOutput.
