Method and system for reducing the number of draw commands issued to a graphics processing unit (gpu)

A system for reducing a number of draw commands issued to a graphics processing unit (GPU), comprising:

• a scene graph generator that generates a first scene graph and a second scene graph, wherein the first scene graph includes a first set of nodes based on a first set of draw commands for rendering one or more objects in a first frame, and wherein the second scene graph includes a second set of nodes based on a second set of draw commands for rendering one or more objects in a second frame;
• and
• an optimizer that identifies a common portion of the first and second frames and replaces a plurality of nodes in the second scene graph with a single node including a single draw command representing draw commands in the plurality of nodes, wherein the common portion corresponds to the plurality of nodes in the first and second scene graphs that are the same,
• wherein the single draw command causes the GPU to retrieve a texture from a memory and display the texture in the second frame, and the texture is based on a rendering of the common portion in the first frame.

A computer-readable medium having stored thereon computer-executable instructions for performing operations, comprising:

• generating a first scene graph including a first set of nodes, the first set of nodes based on a first set of draw commands for rendering one or more objects in a first frame;
• generating a second scene graph including a second set of nodes, the second set of nodes based on a second set of draw commands for rendering one or more objects in a second frame;
• identifying a common portion of the first and second frames, the common portion corresponding to a plurality of nodes in the first and second scene graphs that are the same;
• and
• replacing the plurality of nodes in the second scene graph with a single node including a single draw command representing draw commands in the plurality of nodes,
• the single draw command causing the GPU to retrieve a texture from a memory and display the texture in the second frame, the texture based on a rendering of the common portion in the first frame.
