Public Attributes Documentation​

version​

uint32_t version;

Version of the structure.

transform​

MLTransform transform;

The desired transform of the new Spatial Anchor.

The anchor's transform is set when the anchor is created but may be updated later by the Spatial Anchor system based on factors such as quality of the mapped space and subsequent localizations.

expiration_timestamp_s​

uint64_t expiration_timestamp_s;

The suggested expiration timestamp for this anchor represented in seconds since the Unix epoch.

This is implemented as an expiration timestamp in the future after which the associated anchor should be considered no longer valid and may be removed by the Spatial Anchor system. If the timestamp is set to zero in this struct, the anchor will never expire.
