Abstract

An image-based digital representation of a scenery for visually presenting the scenery is stored in an image information storing structure, which comprises vertices, each representing a digital image, and edges binding together a first vertex with a second vertex. Each edge represents information of a transition between a first image in the first vertex and a second image in the second vertex, the first and the second image depicting different views of the scenery, the first image having a first area and the second image having a second area, wherein the depictions of the first area substantially correspond to the depictions of the second area. The transition information defines a manipulation of at least one of the first and the second images, said manipulation comprising a computation of at least one transition image, the transition image depicting a new view of the scenery depicted in the first and second images.

Also, a method for presentation of a navigation in a scenery, a method for presentation of images, and a device, a method, and a computer program for creating an image information storing structure is disclosed.
