This disclosure is directed to the control of graphical output of a second computing device by a first computing device. According to these techniques, a first computing device may be configured to generate at least one control object that includes at least one control script. The at least one control script is configured to be executed according to an execution environment (e.g., a graphics processing environment) of the second computing device. Once executed, the at least one control script may be configured to access a native application programming interface (API) of the second computing device to cause graphical data to be presented via an output interface (e.g., a display) communicatively coupled to the second computing device based on a context defined by the at least one control object.

Remote rendering control objects

One embodiment of the present invention sets forth a technique for specifying scene programs, where the effect of executing a particular scene program is to generate a sequence of graphics commands. The application programming interface is extended to include calls used to specify a high-level scene program. Upon receiving a high-level scene program, the graphics driver generates a machine code scene program. When an application program emits a call to execute one or more machine code scene programs, the graphics driver transmits corresponding scene programs execution commands to the graphics pre-processing unit. For each scene program execution command, the graphics pre-processing unit processes instructions, programmatically reconfigures the graphics pipeline based on the execution of the machine code scene program, and launches one or more parallel threads that execute commands within the graphics pipeline. Advantageously, using scene programs, application developers may tailor application programs to more effectively dispatch tasks to the GPU.

System and method for enabling scene program functionality

One embodiment of the present invention sets forth a method for accessing, from within a graphics processing unit (GPU), data objects stored in a memory accessible by the GPU. The method comprises the steps of creating a data object in the memory based on a command received from an application program, transmitting an address associated with the data object to the application program for providing data associated with different draw commands to the GPU, receiving a first draw command and the address associated with the data object from the application program, and transmitting the first draw command and the address associated with the data object to the GPU for processing.
