Modification of wave
Make changes to the square limit of
wave
shown in figure 2.9 by working at each of the levels described above. In particular:
a. Add some segments to the primitive
wave
painter of exercise
2.49
(to add a smile, for example).
b. Change the pattern constructed by
corner-split
(for example, by using only one copy of the
up-split
and
right-split
images instead of two).
c. Modify the version of
square-limit
that uses
square-of-four
so as to assemble the corners in a different pattern. (For example, you might make the big Mr. Rogers look outward from each corner of the square.)
