Techniques described in the disclosure are generally related to generating points of a domain. A tessellation unit may determine outer ring point coordinates for a point of an outer ring of the domain, and inner ring point coordinates for a point of an inner ring of the domain. The inner ring is inner to the outer ring within the domain. The tessellation unit may enqueue the inner ring point coordinates at a location of a queue, read the inner ring point coordinates from the queue, and read the outer ring point coordinates from the queue when the outer ring is not an outermost ring, where the outer ring point coordinates were previously enqueued in the queue when the outer ring was a previous inner ring. The tessellation unit may connect the inner ring coordinates and the outer ring coordinates each of which being read from the queue.
