C Specification

The XrSystemDeviceAnchorPersistencePropertiesANDROID structure is defined as:

// Provided by XR_ANDROID_device_anchor_persistence
typedef struct XrSystemDeviceAnchorPersistencePropertiesANDROID {
    XrStructureType    type;
    void*              next;
    XrBool32           supportsAnchorPersistence;
} XrSystemDeviceAnchorPersistencePropertiesANDROID;

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.

  • supportsAnchorPersistence is an XrBool32 indicating if the current system supports anchor persistence for spatial anchors.

Description

An application inspects whether the system is capable of persisting spatial anchors (see xrCreateAnchorSpaceANDROID) by extending the XrSystemProperties with XrSystemDeviceAnchorPersistencePropertiesANDROID structure when calling xrGetSystemProperties.

To query the supported types for the supported trackable anchors an application calls xrEnumerateSupportedPersistenceAnchorTypesANDROID.

If and only if a runtime returns XR_FALSE for supportsAnchorPersistence, the runtime must return XR_ERROR_FEATURE_UNSUPPORTED from device anchor persistence functions that operate on a spatial anchor.

Valid Usage (Implicit)
