A mobile device (104, 204) comprising communications interface (324) for transferring data, a digital camera (328) for obtaining a camera view (102) of the surroundings of the mobile device at a location, a display (330) for visualizing data such as the camera view (102), and an augmented reality (AR) entity (332) configured to transmit, via the communications interface, an indication of the location of the mobile device to an external entity, obtain, by applying data transfer from said external entity via the communications interface, a representation determined on the basis of a number of 3D models (202) of one or more virtual elements (102e, 206a) deemed as visually observable from the location of the mobile device, said representation forming at least a part of at least an approximation of spherical projection (108, 208, 210) of said 3D models, wherein the associated spherical surface is configured to surround the location of the mobile device, and produce an AR view (102d) for visualization on the display on the basis of the camera view and orientation-wise matching portion, such as 2D images and/or parts thereof, of the representation. Related server arrangement and methods are presented.
