Abstract

Methods and devices to enable rendering of graphics data on a computing device having a native rendering engine. The computing device determines the graphics format that is most desirable in light of the nature of the native rendering engine on the device. In some cases, in selecting the most desirable graphics format the device may also assess the nature of the graphics operations likely to be performed on the graphics data, if any. The request to the remote device, such as a server, includes information indicating the target format for the graphics data. The server provides the graphics data in the target format. If the graphics data is not already in the target format the server converts the data to the target format before sending to the computing device. It then stores the converted data to have it available for subsequent requests from the computing device or other computing devices.

Claims

1. A method of enabling rendering of graphics data on a computing device having a native rendering engine, the method comprising:

receiving, at a remote device, from the computing device, a request for graphics data, the graphics data being in an original graphics format different from a format of the native rendering engine, the request indicating a target graphics format corresponding to the native rendering engine on the computing device;

converting, by the remote device, the graphics data from the original graphics format to the target graphics format;

storing a copy of the graphics data in the target graphics format; and

,

sending the computing device, in reply to the request, the graphics data in the target graphics format for rendering on the computing device.

2. The method claimed in claim 1, wherein the original graphics format is 2D and the target graphics format is 3D.

3. The method claimed in claim 2, wherein the native rendering engine on the computing device comprises a 3D renderer.

4. The method claimed in claim 1, wherein the graphics data comprises map data.

5. The method claimed in claim 1, further comprising, on the computing device, determining one or more graphical operations that will be applicable to the graphics data once rendered and selecting the target graphics format based upon the one or more graphical operations and the native rendering engine.

6. The method claimed in claim 5, wherein the one or more graphical operations comprise at least one of pan, zoom, or rotate;

and wherein the native rendering engine is a 3D renderer, the target graphics format is 3D, and the original graphics format is 2D.

7. The method claimed in claim 6, wherein the graphics data comprises map data.

8. A method of enabling rendering of graphics data on a computing device having a native rendering engine, the graphics data being located at a remote device, the method comprising:

receiving a request for the graphics data;

determining a target graphics format based upon the native rendering engine on the computing device;

sending, to the remote device, a request identifying the graphics data and the target graphics format;

receiving, from the remote device, in reply to the request, the graphics data in the target graphics format; and

rendering the graphics data on a display of the computing device.

9. The method claimed in claim 8, wherein the target graphics format is 3D, and wherein the native rendering engine on the computing device comprises a 3D renderer.

10. The method claimed in claim 8, wherein determining the target graphics format includes determining one or more graphical operations that will be applicable to the graphics data once rendered and selecting the target graphics format based upon the one or more graphical operations and the native rendering engine.

11. The method claimed in claim 10, wherein the one or more graphical operations comprise at least one of pan, zoom, or rotate, the native rendering engine is a 3D renderer, and the target graphics format is 3D.

12. The method claimed in claim 8, wherein the graphics data comprises map data.

13. A first computing device to enable rendering of graphics data on a second computing device having a native rendering engine, the first computing device comprising:

a processor;

data storage containing the graphics data; and

a request handler to receive, from the second computing device, a request for the graphics data, the graphics data being in an original graphics format different from a format of the native rendering engine, the request indicating a target graphics format corresponding to the native rendering engine on the second computing device;

wherein the request handler is to convert the graphics data from the original graphics format to the target graphics format, store a copy of the graphics data in the target graphics format in the data storage, and send the second computing device, in reply to the request, the graphics data in the target graphics format for rendering on the second computing device.

14. The first computing device claimed in claim 13, wherein the original graphics format is 2D and the target graphics format is 3D.

15. The first computing device claimed in claim 14, wherein the native rendering engine on the computing device comprises a 3D renderer.

16. The first computing device claimed in claim 13, wherein the graphics data comprises map data.

17. A system comprising the first computing device claimed in claim 13, and further comprising the second computing device, wherein the second computing device includes a processor to determine one or more graphical operations that will be applicable to the graphics data once rendered and to select the target graphics format based upon the one or more graphical operations and the native rendering engine.

18. The system claimed in claim 17, wherein the one or more graphical operations comprise at least one of pan, zoom, or rotate;

and wherein the native rendering engine is a 3D renderer, the target graphics format is 3D, and the original graphics format is 2D.

21. The computing device claimed in claim 20, wherein the target graphics format is 3D, and wherein the native rendering engine on the computing device comprises a 3D renderer.

22. The computing device claimed in claim 20, wherein the graphics data retrieval process is further to determine the target graphics format by determining one or more graphical operations that will be applicable to the graphics data once rendered and selecting the target graphics format based upon the one or more graphical operations and the native rendering engine.
