Method (100) for providing a set of data files from a server computer (40) to a mobile client device (30), the set of data files comprising texture data (21-23) being associated with a portion of a three-dimensional surface (25) in an image scene (20), wherein the image scene (20) is defined by an observation point and a direction and/or angle of view, the set of data files is a subset of data files being stored on the server computer (40), and each data file comprises texture data (21-23) in one of a plurality of different detail levels (331-335), characterized in that the method (100) comprises providing geometry data in a memory of the mobile client device (30), the geometry data being associated with the three-dimensional surface in the image scene (20), selecting data files with texture data (21-23) for being provided by the server computer (40), wherein selecting data files is performed by a calculation unit of the client device (30) based on the geometry data and on visibility conditions of the three-dimensional surface (25) in the image scene (20), and requesting the provision of the selected data files from the server computer (40) to the client device (30). |
