1. A method of controlling display of a three-dimensional map on a computing device, comprising: displaying a view of at least a portion of the map such that the display indicates three-dimensional depth for features in the at least a portion of the map; receiving information indicating selection of a feature in the at least a portion of the map in three-dimensional space; and responsive to said receiving: performing a blur operation on the at least a portion of the map to produce a blurred version of the at least a portion of the map, wherein the blur operation maintains an appearance of three-dimensional depth in the blurred version of the at least a portion of the map; rendering the blurred version of the at least a portion of the map; and rendering an unblurred version of the selected feature within the blurred version of the at least a portion of the map to indicate its selection.
