Abstract

Methods and systems for providing three dimensional graphics to remote computing machines and appliances that include an agent executing on a local computing machine to intercept a plurality of graphics commands generated by a three dimensional application executing on a local computing machine. A first portion of the plurality of graphics commands are encoded by the agent using a first codec, while a second portion of the plurality of graphics commands are encoded by the agent using a second codec. The agent creates a frame comprising the first portion and the second portion of the plurality of graphics commands, compresses the frame, and transmits the frame to a remote computing machine.

Claims

1. A method for remoting three dimensional graphics, the method comprising:

intercepting, by an agent, a plurality of three-dimensional graphics commands generated by an application executing on a local computing machine;

encoding, by the agent, a first portion of the plurality of three-dimensional graphics commands with a first codec;

encoding, by the agent, a second portion of the plurality of three-dimensional graphics commands with a second codec;

creating, by the agent, a frame comprising the first portion and the second portion of the plurality of three-dimensional graphics commands;

compressing the frame by the agent; and

transmitting, by the agent, the frame to a remote computing machine.

4. The method of claim 1, wherein encoding the second portion of the plurality of three-dimensional graphics commands further comprises encoding a second portion of the plurality of three-dimensional graphics commands different from the first portion of the plurality of three-dimensional graphics commands.

5. The method of claim 1, wherein encoding the second portion of the plurality of three-dimensional graphics commands further comprises encoding a second portion of the plurality of three-dimensional graphics commands substantially similar to the first portion of the plurality of three-dimensional graphics commands.

6. The method of claim 1, wherein intercepting further comprises intercepting the three-dimensional graphics commands before they are transmitted to a three dimensional graphics driver.

7. The method of claim 6, further comprising redirecting the three-dimensional graphics commands to a proxy three dimensional graphics driver.

8. The method of claim 1, wherein creating a frame further comprises creating a frame comprising graphics primitives.

9. The method of claim 8, wherein the graphics primitives are DirectX graphics primitives.

10. The method of claim 8, wherein the graphics primitives are OpenGL graphics primitives.

11. The method of claim 8, wherein the graphics primitives are Direct3D graphics primitives.

34. The method of claim 1, wherein vertices or indices are encoded using Huffman encoding.

36. The method of claim 1, wherein textures or surfaces are encoded using JPEG, HD Photo, 2DRLE, PNG, or HD Photo.

12. A system for remoting three dimensional graphics, the system comprising:

a local computing machine executing an application that generates a plurality three-dimensional graphics commands;

a remote computing machine in communication with the local computing machine via a remote presentation protocol; and

an agent executing on the local computing machine to;

intercept the plurality of three-dimensional graphics commands,

encode a first portion of the plurality of three-dimensional graphics commands with a first codec,

encode a second portion of the plurality of three-dimensional graphics commands with a second codec,

create a frame comprising the first portion and the second portion of the plurality of three-dimensional graphics commands,

compress the frame, and

transmit the frame to the remote computing machine.

15. The system of claim 12, wherein the second portion of the plurality of three-dimensional graphics commands is different from the first portion of the plurality of three-dimensional graphics commands.

16. The system of claim 12, wherein the second portion of the plurality of three-dimensional graphics commands is substantially similar to the first portion of the plurality of three-dimensional graphics commands.

17. The system of claim 12, wherein the agent intercepts three-dimensional graphics commands before they are transmitted to a three dimensional graphics driver.

18. The system of claim 17, wherein the agent further redirects the three-dimensional graphics commands to a proxy three dimensional graphics driver.

19. The system of claim 12, wherein the agent creates a frame comprising graphics primitives.

20. The system of claim 19, wherein the graphics primitives are DirectX graphics primitives.

21. The system of claim 19, wherein the graphics primitives are OpenGL graphics primitives.

22. The system of claim 19, wherein the graphics primitives are Direct3D graphics primitives.

35. The system of claim 12, wherein vertices or indices are encoded using Huffman encoding.

37. The system of claim 12, wherein textures or surfaces are encoded using JPEG, HD Photo, 2DRLE, PNG, or HD Photo.
