Abstract

The invention pertains to a method (100) for displaying a representation (1) of a portion of a three-dimensional surface (11) by rendering data representing physical features of the portion of the three-dimensional surface, the data being apportioned into a multitude of tiles (20) at a plurality of different detail levels (331-333), the representation (1) comprising a multitude of image pixels (10), a buffer being assigned to each image pixel (10), the method (100) comprising identifying (110) tiles (20) that need to be rendered, and rendering (150) the identified tiles (20), wherein at least a portion of a tile (20) is displayed by a multitude of image pixels (10), characterized by assigning (130) an unambiguous distance value to each of the identified tiles (20), and storing (140) a default buffer value (18) in the buffers of the image pixels (10), wherein the rendering (150) comprises comparing (160) the buffer values (18) of image pixels (10) and the distance value of a presently rendered tile (20). The invention furthermore pertains to a mobile device (30) and a computer programme product for execution of said method.
