1. A method in a computing device for providing an intuitive display of a building on a digital map, the method comprising:
- displaying a digital map of a geographic area via a user interface of the computing device from a perspective of a virtual camera;
displaying, on the digital map, a three-dimensional (3D) representation of a building located in the geographic area, including displaying an external shell of the building;
receiving, via the user interface, a request to change a position of the virtual camera to approach the 3D representation of the building;
in response to the received request, changing the position of the virtual camera to approach the 3D representation of the building; and
as the position of the virtual camera is changed to approach the 3D representation of the building, (i) when a distance between the position of the virtual camera and the 3D representation of the building meets or exceeds a threshold value, increasing transparency of the external shell of the building while the partially transparent external shell completely obscures indoor map information within the 3D representation of the building and (ii) when the distance between the position of the virtual camera and the 3D representation of the building is smaller than the threshold value;
revealing the indoor map information within the 3D representation of the building through the partially transparent external shell, andincreasing a detail of the indoor map information within the 3D representation of the building.

Abstract
A digital map of a geographic area is displayed via a user interface, and a 3D representation of a building located in the geographic area is displayed on the digital map. A virtual camera is used to view the digital map, and the location of the virtual camera is changeable in response to user input. The external shell of the 3D representation is made increasingly transparent as a virtual camera approaches the 3D representation of the building to reveal indoor information for the building.

9. A computing device comprising:
-
a user interface including a display device; one or more processors; and a memory storing thereon instructions that, when executed by the one or more processors, cause the computing device to; display a digital map of a geographic area via the user interface from a perspective of a virtual camera; display, on the digital map, a three-dimensional (3D) representation of a building located in the geographic area, wherein the 3D representation of the building includes an external shell; receive, via the user interface, a request to change a position of the virtual camera to approach the 3D representation of the building, in response to the received request, change the position of the virtual camera to approach the 3D representation of the building, and as the position of the virtual camera is changed to approach the 3D representation of the building, (i) when a distance between the position of the virtual camera and the 3D representation of the building meets or exceeds a threshold value, increase a transparency of the external shell while the partially transparent external shell completely obscures associated internal features of the building within the 3D representation of the building and (ii) when the distance between the position of the virtual camera and the 3D representation of the building is smaller than the threshold value; reveal the associated internal features within the 3D representation of the building through the partially transparent external shell, and increase a detail of the associated internal features within the 3D representation of the building. - View Dependent Claims (10, 11, 12, 13)
