The tessellation method includes determining whether a previous tag that is identical to the current tag of the current patch is stored in the cache, and transmitting a previous tessellation pattern corresponding to the previous tag stored in the cache to a domain shader when the cache hit. do. The method may include generating a current tessellation pattern corresponding to the current patch by using a tessellator and transmitting the generated current tessellation pattern to the domain shader when the cache misses, and transmitting the generated current tessellation pattern to the cache. Further comprising the step of storing.
