Persistent Nature: A Generative Model of Unbounded 3D Worlds

us to generate arbitrary camera trajectories, such as the six numbered views shown along a cyclic camera path (center). The persistence inherent to our representation stands in contrast to prior auto-regressive methods [42] that do not preserve consistency under circular camera trajectories (right); while the two images shown on the right are at the start and end of a cyclic path, the terrain depicted is completely different. Our method is trained solely from unposed, single-view landscape photos.
