C Specification

The XrSpatialComponentBounded2DListEXT structure is defined as:

// Provided by XR_EXT_spatial_entity
typedef struct XrSpatialComponentBounded2DListEXT {
    XrStructureType               type;
    void*                         next;
    uint32_t                      boundCount;
    XrSpatialBounded2DDataEXT*    bounds;
} XrSpatialComponentBounded2DListEXT;

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.

  • boundCount is a uint32_t describing the count of elements in the bounds array.

  • bounds is an array of XrSpatialBounded2DDataEXT.

Description

The runtime must return XR_ERROR_VALIDATION_FAILURE from xrQuerySpatialComponentDataEXT if XrSpatialComponentBounded2DListEXT is in the next chain of XrSpatialComponentDataQueryResultEXT::next but XrSpatialComponentDataQueryConditionEXT::componentTypeCount is not zero and XR_SPATIAL_COMPONENT_TYPE_BOUNDED_2D_EXT is not included in XrSpatialComponentDataQueryConditionEXT::componentTypes.

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

If xrQuerySpatialComponentDataEXT::snapshot was created from xrCreateSpatialDiscoverySnapshotCompleteEXT, then the runtime must provide XrSpatialBounded2DDataEXT::center in XrCreateSpatialDiscoverySnapshotCompletionInfoEXT::baseSpace and XrCreateSpatialDiscoverySnapshotCompletionInfoEXT::time.

If xrQuerySpatialComponentDataEXT::snapshot was created from xrCreateSpatialUpdateSnapshotEXT, then the runtime must provide XrSpatialBounded2DDataEXT::center in XrSpatialUpdateSnapshotCreateInfoEXT::baseSpace and XrSpatialUpdateSnapshotCreateInfoEXT::time.
