Abstract

Method and systems for processing at least one three-dimensional (3D) graphic object include: identifying a change of 3D graphic objects, creating a message, assigning a unique identifier; and forwarding the message and the unique identifier to a scene engine. The change is made by an authoring tool. The message is embedded with change information corresponding to the change. The scene engine functions can be performed by the same or a different computing device as the computing device performing the authoring tool.

Claims

1. A method for processing at least one three-dimensional (3D) graphic object on a first computing device, the method comprising:

identifying a change of the at least one 3D graphic object, wherein the change is made by an authoring tool, wherein the authoring tool is a program executed by the first computing device or by a second computing device;

creating a message, wherein the message is embedded with change information corresponding to the change;

assigning an unique identifier for the message; and

forwarding the message and the unique identifier to a scene engine, wherein the scene engine is a program executed by the first computing device, by the second computing device, or by a third computing device.

2. The method of claim 1, further comprising:

storing the message in a queue when the message is not ready for forwarding after creation; and

retrieving the message from the queue when the message is ready for forwarding.

3. The method of claim 2, further comprising discarding the message from the queue when the message is outdated.

4. The method of claim 2, further comprising discarding the message from the queue when the queue is full.

5. The method of claim 1, wherein the change is identified by using an application programming interface (API) of the authoring tool.

6. The method of claim 1, wherein the change is identified by computing a hash code of the at least one 3D graphic object.

7. The method of claim 1, wherein the message is forwarded through a network using a Transmission Control Protocol (“

TCP”

) protocol.

8. The method of claim 1, wherein the change information contains raw data corresponding to the change.

9. The method of claim 1, wherein the change information is created after reducing complexity of raw data corresponding to the change.

10. The method of claim 1, wherein the change is selected from the group consisting of a skinning change, a texture change, a scene change, a lighting change, a shader change, a coordination change, a vertex change, a materials change, and a mesh change.

11. The method of claim 1, wherein the unique identifier is embedded in the message.

12. The method of claim 1, wherein the unique identifier corresponds to the change information.

13. The method of claim 1, wherein the unique identifier corresponds to the message.

14. A 3D graphic object processing system comprising:

at least one processing unit;

a computer-readable storage medium having program instructions executable by the at least one processing unit;

wherein the program instructions identify a change of at least one 3D graphic object, wherein the change is made by an authoring tool, wherein the authoring tool is a program executed by the 3D graphic object processing system or by a first computing device;

wherein the program instructions create a message, wherein the message contains a unique identifier and change information corresponding to the change;

wherein the program instructions forward the message to a scene engine, wherein the scene engine is a program executed by the system, by the first computing device or by a second computing device.

15. The system of claim 14, wherein the computer-readable storage medium further comprises program instructions executable by the at least one processing unit for:

storing the message in a queue when the message is not ready for forwarding after creation; and

retrieving the message from the queue when the message is ready for forwarding.

16. The system of claim 15, wherein the computer-readable storage medium further comprises program instructions executable by the at least one processing unit for discarding the message from the queue when the message is outdated.

17. The method of claim 15, wherein the computer-readable storage medium further comprises program instructions executable by the at least one processing unit for discarding the message from the queue when the queue is full.

18. The system of claim 14, wherein the change is identified by using an API of the authoring tool.

19. The system of claim 14, wherein the change is identified by computing a hash code of the at least one 3D graphic object.

20. The system of claim 14, wherein the message is forwarded through a network using TCP protocol.

21. The system of claim 14, wherein the change information contains raw data corresponding to the change.

22. The system of claim 14, wherein the change information is created after reducing the complexity of raw data corresponding to the change.

23. The system of claim 14, wherein the change is selected from the group consisting of a skinning change, a texture change, a scene change, a lighting change, a shader change, a coordination change, a vertex change, a materials change, and a mesh change.

24. The system of claim 14, wherein the unique identifier is embedded in the message.

25. The system of claim 14, wherein the unique identifier corresponds to the change information.

26. The system of claim 14, wherein the unique identifier corresponds to the message.
