Abstract: A method of temporal instantiation for an augmented-reality digital service. The method includes: a) obtaining an indication of a chosen date within a predefined time coverage interval, b) accessing a library of 3D temporal objects, a 3D temporal object comprising a plurality of instances, an instance being a 3D object associated with a validity time interval forming a continuous portion of the time coverage interval. The method further includes, for at least one 3D temporal object in the library of which an instance is associated with a validity time interval including the chosen date: c) selecting, from the library, only the instance associated with the validity time interval that includes the chosen date, and d) delivering the selected instance with a view to rendering it for a user. An associated computer program and storage medium are also provided.
