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, the application having an application context;

determining, by the agent, to render a portion of the plurality of three-dimensional graphics commands in a rendering location;

analyzing, by the agent, the characteristics of a remote computing machine;

determining, by the agent, a first rendering location and reinitializing the application context to select the first rendering location;

rendering, by the agent, a first portion of the plurality of three-dimensional graphics commands at the first rendering location;

reanalyze, by the agent, the characteristics of the remote computing machine;

determining, by the agent, a second rendering location and reinitializing the application context to select the second rendering location;

transmitting, by the agent, a second portion of the plurality of three-dimensional graphics commands and the rendered first portion of the plurality of three-dimensional graphics commands to the second rendering location; and

rendering, by the agent, the second portion of the plurality of the three-dimensional graphics commands at the second rendering location.

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

3. The method of claim 1, wherein rendering the second portion of the plurality of three-dimensional graphics commands further comprises rendering 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.

4. 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.

5. The method of claim 4, further comprising redirecting the three-dimensional graphics commands to a proxy three dimensional graphics driver.

6. The method of claim 1, wherein certain types of three-dimensional graphics commands are rendered at the rendering location based on a policy.

7. The method of claim 1, wherein the portion of the plurality of three-dimensional graphics commands is determined by at least one of a type of graphic element, a size of graphical data, a transaction, and a type of graphics primitives.

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

a local computing machine executing an application, having an application context, 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 configured to;

intercept the plurality of three-dimensional graphics commands;

determine to render a portion of the plurality of three-dimensional graphics commands in a rendering location;

analyze the characteristics of the remote computing machine;

determine a first rendering location and reinitializing the application context to select the first rendering location;

render a first portion of the plurality of three-dimensional graphics commands at the first rendering location;

reanalyze the characteristics of the remote computing machine;

determine a second rendering location and reinitializing the application context to select the second rendering location;

transmit a second portion of the plurality of three-dimensional graphics commands and the rendered first portion of the plurality of three-dimensional graphics commands to the second rendering location; and

render the second portion of the plurality of the three-dimensional graphics commands at the second rendering location.

9. The system of claim 8, 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.

10. The system of claim 8, 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.

11. The system of claim 8, wherein the agent intercepts three-dimensional graphics commands before they are transmitted to a three dimensional graphics driver.

12. The system of claim 11, wherein the agent further redirects the three-dimensional graphics commands to a proxy three dimensional graphics driver.

13. The system of claim 8, wherein the agent executes on the remote computing machine.

14. The system of claim 8, wherein the agent executes on the local computing machine.
