It includes natural quadrics (cylinder, cone and sphere), revolute quadrics, tori, pipes and Dupin cyclide. Also, canal surfaces are among the surfaces which are easier to describe both analytically and operationally, (CARMO, 1976), (O'NEIL, 1983), (FAROUKI; NEFF, 1990), (LU, 1994), (GRAY, 1998), (PETERNELL; POTTMANN, 1997), (ZHU et al., 2005), (XU et al., 2006), (KORPINAR; TURHAN, 2011), (TURHAN; KORPINAR, 2011a).
