1. A method for detecting a dirty region within a frame encompassing three dimensional graphics and three dimensional graphics primitives, the method comprising:

  • intercepting, via an agent executing on a local computing machine, a function call issued by an application generating three dimensional graphics;

    identifying, by the agent and responsive to intercepting the function call, at least one location within a frame containing three dimensional graphics commands generated by the application, the location corresponding to a drawing region;

    determining at least a portion of the three dimensional graphics commands, associated with the at least one location within the frame, changed; and

    extracting the changed portion of the three dimensional graphics commands.
