Abstract

A method of displaying a navigation map includes determining a route of a vehicle. A two-dimensional footprint of a building disposed within a geographic area is received within the vehicle. The geographic area includes the route of the vehicle. Attribute information associated with the building is received. The attribute information is received within the vehicle. A visual representation of the building is rendered based upon the two-dimensional footprint and the attribute information.

Claims

1. A method of displaying a navigation map, comprising the steps of:

determining a route of a vehicle;

receiving within the vehicle a two-dimensional footprint of a building that is disposed within a geographic area, the geographic area including the route of the vehicle;

receiving attribute information associated with the building, the attribute information being received within the vehicle; and

rendering a visual representation of the building based upon the two-dimensional footprint and the attribute information.

2. The method of claim 1 wherein the attribute information comprises the building'"'"'s type.

3. The method of claim 2 wherein a color scheme of the rendered building is dependent upon the building'"'"'s type.

4. The method of claim 2 wherein texturing of the rendered building is dependent upon the building'"'"'s type.

5. The method of claim 1 wherein the attribute information comprises the building'"'"'s height.

6. The method of claim 1 comprising the further steps of:

determining a target performance level of a hardware platform within the vehicle; and

controlling the geometric complexity and/or appearance complexity of the rendering of the building in order to meet the target performance level.

7. The method of claim 1 comprising the further steps of:

decomposing the two-dimensional footprint into tractable parts;

and modeling each of the tractable parts separately in combination with a respective portion of the geometry information associated with each of the tractable parts, wherein the rendering of the visual representation of the building is based upon a combination of the modelings of each of the tractable parts.

8. A method of displaying a navigation map, comprising the steps of:

determining a route of a vehicle;

receiving geographical coordinates of a location of the vehicle;

determining a geographic area in which the geographical coordinates are disposed;

receiving data associated with buildings that are disposed within the geographic area, the geographic area including the route of the vehicle, the data including;

building types; and

building heights; and

rendering each of the buildings based upon;

the geographic area in which the building is disposed;

the building'"'"'s type; and

the building'"'"'s height.

9. The method of claim 8 wherein each of the buildings comprises a non-landmark building.

10. The method of claim 8 wherein the color and texture in which each building is rendered is dependent upon the building'"'"'s type.

11. The method of claim 10 wherein the color and texture in which each building is rendered is dependent upon the geographic area in which the building is disposed.

12. The method of claim 8 wherein buildings of the same type and of the same geographic area are rendered in the same colors and same texture.

13. The method of claim 8 wherein a color scheme and texturing of each of the rendered buildings is dependent upon each of the buildings'"'"' type.

14. The method of claim 8 comprising the further steps of:

determining a target performance level of a hardware platform within the vehicle; and

controlling the geometric complexity and/or appearance complexity of the rendering of each of the buildings in order to meet the target performance level.

15. A method of displaying a navigation map, comprising the steps of:

determining a route of a vehicle;

receiving within the vehicle a two-dimensional footprint of a building that is disposed within a geographic area, the geographic area including the route of the vehicle;

decomposing the two-dimensional footprint into tractable parts;

modeling each of the tractable parts separately in combination with a respective portion of the geometry information associated with each of the tractable parts; and

rendering a visual representation of the building based upon a combination of the modelings of each of the tractable parts.

16. The method of claim 15 wherein a color scheme of the rendered building is dependent upon the building'"'"'s type.

17. The method of claim 16 wherein texturing of the rendered building is dependent upon the building'"'"'s type.

18. The method of claim 15 comprising the further steps of

determining a target performance level of a hardware platform within the vehicle;

and

controlling the geometric complexity and/or appearance complexity of the rendering of the building in order to meet the target performance level.

19. The method of claim 15 wherein the visual representation of the building is rendered based upon:

the geographic area in which the building is disposed;

the building'"'"'s type; and

the building'"'"'s height.

20. The method of claim 19 wherein all the visual representations of said buildings of a same said type are rendered with a same color scheme and with same texturing.
