Abstract: A system, method, and computer program product are provided for tessellation using shaders. New graphics pipeline stages implemented by shaders are introduced, including an inner ring shader, an outer edge shader, and topologic shader, which work together with a domain shader and geometry shader to provide tessellated points and primitives. A hull shader is modified to compute values used by the new shaders to perform tessellation algorithms. This approach provides parallelism and customizability to the presently static tessellation engine implementation.
