EFFICIENT TESSELLATION CACHE

Systems and methods may provide for conducting a region determination of whether one or more domain points associated with a tessellated patch are shared between multiple region sets of the tessellated patch. If the one or more domain points are not shared between multiple region sets of the tessellated patch, an intra-region cache may be automatically interrogated for non-shared shading data. If the one or more domain points are shared between multiple region sets of the tessellated patch, an inter-region cache may be automatically interrogated for shared shading data. In one example, one or more references to the shared shading data is generated and associated with the one or more domain points when cache hits occur in the inter-region cache.
