Abstract
Systems, methods, and computer readable media to implement tessellation edge shaders. Various embodiments receive tessellation patch information that includes patch information and shared edges for the patches. Based on the received patch information, edge tessellation levels for the shared edges may be determined and used to modify edge tessellation levels initially computed for the shared edges. The various embodiments can then generate vertices for a shared edge with the updated edge tessellation levels to adjoin the shared edges without forming cracks. The vertices may be used to render a surface of an object within a digital image or a sequence of digital images.
