1. A method for performing tessellation in a single pass through a graphics processor, the method comprising:

  • configuring a first set of processing units of the graphics processor to execute a tessellation control shader to process surface patches and produce a graphics primitive including multiple vertices;

    configuring a second set of the processing units within the graphics processor to execute a tessellation evaluation shader to each process one of the multiple vertices; and

    executing the tessellation control shader and the tessellation evaluation shader to tessellate the surface patches in a single pass through the first set of processing units and the second set of processing units to produce processed vertices.
