Animation showing sequential percentags of the surface according to increase in the u parameter. Color is assigned according to v parameter.
Animation showing sequential percentages of the surface according to increase in the v parameter. Color is messed up, but is supposed to be assigned according to v parameter.
Grid skeleton of the surface, executing the same rotations as in the previous movie.
