(i) The fusion of shapes
There are both unmixed and mixed ways of combining two units. The
unmixed type combines only the same units, like A1+A1
or A2+A2. The mixed one means the mixing of the two
units which resemble each other in shape but differ strictly in detail,
like A1+A2. In both the ways fusion is possible and
many new shapes are created by osculating (touching).
· The unmixed type with
2 units
Shapes like those in page 96 are produced. There
are many other possibilities as you can
imagine from the illustrations on the previous page.
· The mixed type with 2
units
In addition to the typical arrow (C1), different varieties of
shapes are created (Fig. 151).
In this case, it is good to make such figures as those of page
97 to plan to create many
shapes.
· The unmixed type with
4 units
As I gave examples in Figure 152, there are two types. One is a repetition
of the shapes
which I mentioned before (those in Figure 149),
and in the other type completely new
shapes appear.
· The mixed type with 4
units
There are also many shapes with this type. Even if you just combine C1
units, you will
get a variety of shapes, among which only five examples are shown (Fig.
153).
